This is an abbreviated text supplementing the content of three sets of slides used in a short course that has been presented by the author at several workshops. The slides should be viewed in the order of (1) Introduction and models, (2) Delineation and estimation, and (3) Combining estimates and summary. References cited in the slides are listed at the end of this text. The purpose of the three-part form of mineral resource assessments discussed in the accompanying slides is to make unbiased quantitative assessments in a format needed in decision-support systems so that consequences of alternative courses of action can be examined. The three-part form of mineral resource assessments was developed to assist policy makers evaluate the consequences of alternative courses of action with respect to land use and mineral-resource development. The audience for three-part assessments is a governmental or industrial policy maker, a manager of exploration, a planner of regional development, or similar decision-maker. Some of the tools and models presented here will be useful for selection of exploration sites, but that is a side benefit, not the goal. To provide unbiased information, we recommend the three-part form of mineral resource assessments where general locations of undiscovered deposits are delineated from a deposit type's geologic setting, frequency distributions of tonnages and grades of well-explored deposits serve as models of grades and tonnages of undiscovered deposits, and number of undiscovered deposits are estimated probabilistically by type. The internally consistent descriptive, grade and tonnage, deposit density, and economic models used in the design of the three-part form of assessments reduce the chances of biased estimates of the undiscovered resources. What and why quantitative resource assessments: The kind of assessment recommended here is founded in decision analysis in order to provide a framework for making decisions concerning mineral

The United Nations' endeavour to standardize mineral resource classification

International Nuclear Information System (INIS)

Schanz, J.J. Jr.

1980-01-01

The United Nations' Economic and Social Council passed a resolution in July 1975 calling for the development of a mineral resources classification system to be used in reporting data to the United Nations. Following preparation of background papers and an agenda by the UN Centre for Natural Resources, Energy and Transport, a panel of experts recommended a classification system to the Council's Committee on Natural Resources. The Committee met in Turkey in June 1979 and has reported favourably to the Council on the proposed system. The classification system is designed to provide maximum capability for requesting and receiving data from the resources data systems already used internally by major mineral producing nations. In addition, the system provides for flexibility in adjusting to the particular needs of individual mineral commodities. The proposed system involves three basic categories of in-situ resources: R-1, reliable estimates of known deposits; R-2, preliminary estimates of the extensions of known deposits; and, R-3, tentative estimates of quantities to be found in undiscovered deposits. As an option for given countries and commodities, the R-1 category can be further sub-divided into: R-1-E, economic; R-1-M, marginal; and R-1-S, sub-economic. Finally, the classification scheme provides for all categories to have a parallel set of estimates of recoverable mineral quantities. (author)

Many changes have taken place in the mineral resource sector since the publication by the U.S. Geological Survey of Professional Paper 820, “United States Mineral Resources,” which is a review of the long-term United States resource position for 65 mineral commodities or commodity groups. For example, since 1973, the United States has continued to become increasingly dependent on imports to meet its demands for an increasing number of mineral commodities. The global demand for mineral commodities is at an alltime high and is expected to continue to increase, and the development of new technologies and products has led to the use of a greater number of mineral commodities in increasing quantities to the point that, today, essentially all naturally occurring elements have several significant industrial uses. Although most mineral commodities are present in sufficient amounts in the earth to provide adequate supplies for many years to come, their availability can be affected by such factors as social constraints, politics, laws, environmental regulations, land-use restrictions, economics, and infrastructure.This volume presents updated reviews of 23 mineral commodities and commodity groups viewed as critical to a broad range of existing and emerging technologies, renewable energy, and national security. The commodities or commodity groups included are antimony, barite, beryllium, cobalt, fluorine, gallium, germanium, graphite, hafnium, indium, lithium, manganese, niobium, platinum-group elements, rare-earth elements, rhenium, selenium, tantalum, tellurium, tin, titanium, vanadium, and zirconium. All these commodities have been listed as critical and (or) strategic in one or more of the recent studies based on assessed likelihood of supply interruption and the possible cost of such a disruption to the assessor. For some of the minerals, current production is limited to only one or a few countries. For many, the United States currently has no mine production or any

Preliminary Assessment of Non-Fuel Mineral Resources of Afghanistan, 2007

2007-01-01

Introduction Afghanistan has abundant mineral resources, including known deposits of copper, iron, barite, sulfur, talc, chromium, magnesium, salt, mica, marble, rubies, emeralds, lapis lazuli, asbestos, nickel, mercury, gold and silver, lead, zinc, fluorspar, bauxite, beryllium, and lithium (fig. 1). Between 2005 and 2007, the U.S. Agency for International Development (USAID) funded a cooperative study by the U.S. Geological Survey (USGS) and the Afghanistan Geological Survey (AGS) to assess the non-fuel mineral resources of Afghanistan as part of the effort to aid in the reconstruction of that country. An assessment is an estimation or evaluation, in this instance of undiscovered non-fuel mineral resources. Mineral resources are materials that are in such form that economic extraction of a commodity is currently or potentially feasible. In this assessment, teams of scientists from the USGS and the AGS compiled information about known mineral deposits and then evaluated the possible occurrence of undiscovered deposits of all types. Quantitative probabilistic estimates were made for undiscovered deposits of copper, mercury, rare-earth elements, sulfur, chromite, asbestos, potash, graphite, and sand and gravel. These estimates were made for undiscovered deposits at depths less than a kilometer. Other deposit types were considered and discussed in the assessment, but quantitative estimates of numbers of undiscovered deposits were not made. In addition, the assessment resulted in the delineation of 20 mineralized areas for further study, of which several may contain resources amenable to rapid development.

Economic filters for evaluating porphyry copper deposit resource assessments using grade-tonnage deposit models, with examples from the U.S. Geological Survey global mineral resource assessment: Chapter H in Global mineral resource assessment

An analysis of the amount and location of undiscovered mineral resources that are likely to be economically recoverable is important for assessing the long-term adequacy and availability of mineral supplies. This requires an economic evaluation of estimates of undiscovered resources generated by traditional resource assessments (Singer and Menzie, 2010). In this study, simplified engineering cost models were used to estimate the economic fraction of resources contained in undiscovered porphyry copper deposits, predicted in a global assessment of copper resources. The cost models of Camm (1991) were updated with a cost index to reflect increases in mining and milling costs since 1989. The updated cost models were used to perform an economic analysis of undiscovered resources estimated in porphyry copper deposits in six tracts located in North America. The assessment estimated undiscovered porphyry copper deposits within 1 kilometer of the land surface in three depth intervals.

Mineral resources of Peru's ancient societies

Northern Peru has an exceptionally rich archaeological heritage that includes metalwork, ceramics and textiles. The success of at least a half-dozen pre-Columbian societies dating back 3,000 years and subsequent Spanish colonization in the 1400s has rested on the effective use of northern Peru's abundant resources. In the summer of 2000, my son Matt and I learned about that connection firsthand by volunteering at the Santa Rita B archaeological site in the Chao Valley near Trujillo in northern Peru. Riding donkey-back through the Andes and talking with local people, we got our hands dirty in the rich archaeology and geology of the area. We were able to correlate mineral occurrences to their various roles in society - opening a window into the region's fascinating past. From construction to metallurgy, pre-Columbian societies flourished and advanced because of their understanding and use of the available mineral resources.

Mineral Resource Information System for Field Lab in the Osage Mineral Reservation Estate

The Osage Mineral Reservation Estate is located in Osage County, Oklahoma. Minerals on the Estate are owned by members of the Osage Tribe who are shareholders in the Estate. The Estate is administered by the Osage Agency, Branch of Minerals, operated by the U.S. Bureau of Indian Affairs (BIA). Oil, natural gas, casinghead gas, and other minerals (sand, gravel, limestone, and dolomite) are exploited by lessors. Operators may obtain from the Branch of Minerals and the Osage Mineral Estate Tribal Council leases to explore and exploit oil, gas, oil and gas, and other minerals on the Estate. Operators pay a royalty on all minerals exploited and sold from the Estate. A mineral Resource Information system was developed for this project to evaluate the remaining hydrocarbon resources located on the Estate. Databases on Microsoft Excel spreadsheets of operators, leases, and production were designed for use in conjunction with an evaluation spreadsheet for estimating the remaining hydrocarbons on the Estate.

The economy, national security, and standard of living of the United States depend heavily on adequate and reliable supplies of energy and mineral resources. Based on population and consumption trends, the Nation’s use of energy and minerals can be expected to grow, driving the demand for ever broader scientific understanding of resource formation, location, and availability. In addition, the increasing importance of environmental stewardship, human health, and sustainable growth places further emphasis on energy and mineral resources research and understanding. Collectively, these trends in resource demand and the interconnectedness among resources will lead to new challenges and, in turn, require cutting- edge science for the next generation of societal decisions. The long and continuing history of U.S. Geological Survey contributions to energy and mineral resources science provide a solid foundation of core capabilities upon which new research directions can grow. This science strategy provides a framework for the coming decade that capitalizes on the growth of core capabilities and leverages their application toward new or emerging challenges in energy and mineral resources research, as reflected in five interrelated goals.

Sustainable mineral resources management: from regional mineral resources exploration to spatial contamination risk assessment of mining

Science.gov (United States)

Jordan, Gyozo

2009-07-01

Wide-spread environmental contamination associated with historic mining in Europe has triggered social responses to improve related environmental legislation, the environmental assessment and management methods for the mining industry. Mining has some unique features such as natural background contamination associated with mineral deposits, industrial activities and contamination in the three-dimensional subsurface space, problem of long-term remediation after mine closure, problem of secondary contaminated areas around mine sites, land use conflicts and abandoned mines. These problems require special tools to address the complexity of the environmental problems of mining-related contamination. The objective of this paper is to show how regional mineral resources mapping has developed into the spatial contamination risk assessment of mining and how geological knowledge can be transferred to environmental assessment of mines. The paper provides a state-of-the-art review of the spatial mine inventory, hazard, impact and risk assessment and ranking methods developed by national and international efforts in Europe. It is concluded that geological knowledge on mineral resources exploration is essential and should be used for the environmental contamination assessment of mines. Also, sufficient methodological experience, knowledge and documented results are available, but harmonisation of these methods is still required for the efficient spatial environmental assessment of mine contamination.

Resource nationalism in Indonesia—Effects of the 2014 mineral export ban

Science.gov (United States)

Lederer, Graham W.

2016-09-27

Resource nationalism encompasses a broad range of political and economic actions taken by Governments to regulate the extraction of natural resources within their borders. Policies such as increased tariffs or export restrictions can have far-reaching economic effects on international trade. As the Governments of several developing countries consider enacting nationalistic policies, an examination of the 2014 mineral export ban in Indonesia provides an instructive example of the possible impacts of resource nationalism. Significant changes in the production and trade of unprocessed (that is, ores and concentrates) and processed (that is, refined metal) aluminum, copper, and nickel before and after the export ban form the basis of this study.The U.S. Geological Survey (USGS) National Minerals Information Center (NMIC) tracks production and trade of mineral commodities between producer and consumer countries. Materials flow studies clarify the effects of an export ban on different mineral commodities by assessing changes in production, processing capacity, and trade. Using extensive data collection and monitoring procedures, the USGS NMIC investigated the effects of resource nationalism on the flow of mineral commodities from Indonesia to the global economy.

A probabilistic mineral resource assessment of metal resources in undiscovered porphyry copper deposits of the Ural Mountains in Russia and Kazakhstan was done using a quantitative form of mineral resource assessment. Permissive tracts were delineated on the basis of mapped and inferred subsurface distributions of igneous rocks assigned to tectonic zones that include magmatic arcs where the occurrence of porphyry copper deposits within 1 km of the Earth's surface are possible. These permissive tracts outline four north-south trending volcano-plutonic belts in major structural zones of the Urals. From west to east, these include permissive lithologies for porphyry copper deposits associated with Paleozoic subduction-related island-arc complexes preserved in the Tagil and Magnitogorsk arcs, Paleozoic island-arc fragments and associated tonalite-granodiorite intrusions in the East Uralian zone, and Carboniferous continental-margin arcs developed on the Kazakh craton in the Transuralian zone. The tracts range from about 50,000 to 130,000 km2 in area. The Urals host 8 known porphyry copper deposits with total identified resources of about 6.4 million metric tons of copper, at least 20 additional porphyry copper prospect areas, and numerous copper-bearing skarns and copper occurrences.Probabilistic estimates predict a mean of 22 undiscovered porphyry copper deposits within the four permissive tracts delineated in the Urals. Combining estimates with established grade and tonnage models predicts a mean of 82 million metric tons of undiscovered copper. Application of an economic filter suggests that about half of that amount could be economically recoverable based on assumed depth distributions, availability of infrastructure, recovery rates, current metals prices, and investment environment.

Full Text Available Market transformations in Russia became foundations for formation and development of a new scientific and practical field in economics – logistics. Out of more than 30 existing definitions of logistics the authors according to their opinion have chosen the most appropriate. Logistics of mineral resources should be attributed to production (industrial logistics. It is a proven fact that processes of supply chain management in mining industry and its infrastructure in the framework of mineral resources chain have some fundamental distinctions. Importance of material resources recycling in theory and practice of mineral resources logistics has been highlighted. Special features of merchandise assortment and classifications in the mining industry have been examined in conjunction with substantial contents of material flow. Special consideration has been given to relevant issues in the field of price formation for mining produce, in the view of specific relations between its costs and logistic procurement of the industry. Moreover, questions of inventory control in the mining industry, activity of commodity exchanges, management of mining logistics system have been addressed.

Management of Canadian mineral resources: an industry viewpoint

Energy Technology Data Exchange (ETDEWEB)

Powis, A

1976-03-01

Federal and provincial governments in Canada are developing strategies for a national mineral policy, the theme being to obtain optimum benefit for Canada from present and future use of minerals. The provisions of the British North America Act, the centerpiece of Canada's constitution, place ownership of natural resources under the jurisdiction of the province in which they are found, although it retains exclusive authority for the Federal government over the export and interprovincial trade of such resources. Contradiction and challenges are now being experienced between these two levels of government, resulting in excess taxation policies in the minerals industry. Mr. Powis discussed these issues at the 32nd Annual Conference of Provincial Ministers of Mines in Saskatoon on September 15, 1975. The roles of the private sector and governments, the Economic Council of Canada trade strategy report, the mineral area planning study, and the public and political perceptions are reviewed. Options for the future are summarized. Mr. Powis concludes that the atmosphere of confrontation in Canadian mineral policy leads to irrational management of Canadian resources; further, he sees a lack of communication between industry and government as complicating the issue. The Canadian mining industry also faces the other serious problems: (1) mining problems in inhospitable areas; (2) continuing difficulty in attracting and retaining trained labor forces; (3) increasing costs of exploration and transport; (4) competing with larger and more accessible deposits in other parts of the world; and (5) the impact of inflation in all areas of the industry.

1983-01-01

Geologic, geochemical, and geophysical investigations and a survey of mines and prospects indicate that the Sugaloaf Roadless Area contains subeconomic graphite and magnesian marble resources. Parts of the area have a low potential for the occurrence of additional low-grade graphite resources, but there is no potential for additional magnesian marble resources within the roadless area. Sand, gravel, and construction stone other than carbonate rocks are found in the roadless area, but similar or better quality materials are abundant and more accessible outside the area. The roadless area has no identified energy mineral resources, but parts of the area have a low to moderate potential for low-grade uranium resources. There are no identified metallic mineral resources within the area, and there is no evidence of a potential for the occurrence of such resources. No previously unknown mineral occurrence was located during this study.

World Mineral resources and the Limits to Economic Growth

Bardi Ugo

2014-03-01

Full Text Available This presentation describes how the present economic situation can be described in terms of the system dynamics models developed in the series of studies that were titled “The Limits to Growth”. The result of this examination is that mineral depletion may be a major factor in causing the slowdown in economic growth in several countries. The effect is not the result of “running out” of any resource, but of the gradual increase in extraction costs which is forcing the economy to dedicate larger and larger resources to the production of mineral commodities.

At the request of the U.S. Bureau of Land Management, approximately 105,200 acres of the Turtle Mountains Wilderness Study Area (CDCA-307) were evaluated for mineral resources (known) and resource potential (undiscovered). In this report, the area studied is referred to as "the wilderness study area" or simply "the study area"; any reference to the Turtle Mountain Wilderness Study Area refers only to that part of the wilderness study area for which a mineral survey was requested by the U.S. Bureau of Land Management.The wilderness study area is in southeastern San Bernardino County, Calif. Gold, silver, copper, and lead have been mined within and adjacent to the study area. Copper-zinc-silver-gold mineral occurrences are found in the southern part and gold-silver mineral occurrences are found in the northern part of the study area; identified low- to moderate-grade gold-silver resources occur adjacent to the study area along the western boundary. Six areas in the south-central and northwestern parts of the study area have high resource potential, two broad areas have moderate resource potential, and part of the southwest corner has low resource potential for lode gold, silver, and associated copper, lead, zinc, molybdenum, and tungsten. Alluvium locally within one of these areas has moderate resource potential for placer gold and silver, and the entire area has low resource potential for placer gold and silver. There is low resource potential for perlite, ornamental stone (onyx marble and opal), manganese, uranium and thorium, pegmatite minerals, and oil and gas within the study area. Sand and gravel are abundant but are readily available outside the wilderness study area.

Mineral Resources: Reserves, Peak Production and the Future

Directory of Open Access Journals (Sweden)

Lawrence D. Meinert

2016-02-01

Full Text Available The adequacy of mineral resources in light of population growth and rising standards of living has been a concern since the time of Malthus (1798, but many studies erroneously forecast impending peak production or exhaustion because they confuse reserves with “all there is”. Reserves are formally defined as a subset of resources, and even current and potential resources are only a small subset of “all there is”. Peak production or exhaustion cannot be modeled accurately from reserves. Using copper as an example, identified resources are twice as large as the amount projected to be needed through 2050. Estimates of yet-to-be discovered copper resources are up to 40-times more than currently-identified resources, amounts that could last for many centuries. Thus, forecasts of imminent peak production due to resource exhaustion in the next 20–30 years are not valid. Short-term supply problems may arise, however, and supply-chain disruptions are possible at any time due to natural disasters (earthquakes, tsunamis, hurricanes or political complications. Needed to resolve these problems are education and exploration technology development, access to prospective terrain, better recycling and better accounting of externalities associated with production (pollution, loss of ecosystem services and water and energy use.

World mineral energy resources and their distribution in time and space

If the estimated total geological potential of the world mineral energy resources is reduced to a common denominator, then the total resources are estimated at 20 600 terawatt years (TWyr). Assuming that all these resources are recoverable, and applying today's technology, they would suffice for 1 700 years under no-growth conditions and approximately 130 years assuming an annual growth rate of 3%. It should, however, be borne in mind that only about 15% (or 3 100 TWry) of the world's resources can be regarded as proved or partly proved and recoverable at current price levels and with current technology. Assuming a no-growth scenario, these resources will meet future energy requirements for a period of approximately 260 years. At a 3% annual growth rate resources will last for about 70 years. From these figures it is clear that the known mineral energy resources will be depleted in the near future. The challenge to the geologist to locate additional energy potential is enormous and in order to do so, the distribution of known resources in time and space was reappraised. The present investigation confirms the time-bound character of the mineralising processes. These took place in a series of clearly defined rhythms ranging from the early Proterozoic to the Recent. Uranium and thorium constitute the only energy resources of the Proterozoic. In contrast, the Phanerozoiceon contains the totality of fossil fuels and at least 60% of the nuclear resources; strata younger than 600 Ma therefore represent the most favourable target areas for prospecting

Beryllium—A critical mineral commodity—Resources, production, and supply chain

Science.gov (United States)

Lederer, Graham W.; Foley, Nora K.; Jaskula, Brian W.; Ayuso, Robert A.

2016-11-14

Beryllium is a lightweight metallic element used in a wide variety of specialty and industrial applications. As a function of its unique chemical and physical properties, such as a high stiffness-to-weight ratio, resistance to temperature extremes, and high thermal conductivity, beryllium cannot be easily replaced by substitute materials in applications where combinations of these properties make it the material of choice. Because the number of beryllium producers is limited and the use of substitute materials in specific defense-related applications that are vital to national security is inadequate, several studies have categorized beryllium as a critical and strategic material. This categorization has led to the United States Government recommending that beryllium be stockpiled for use in the event of a national emergency. As of December 31, 2015, the National Defense Stockpile inventory of hot-pressed beryllium metal powder, structured beryllium metal powder, and vacuum-cast beryllium metal totaled 78 metric tons (t).The U.S. Geological Survey (USGS) Mineral Resources Program supports research on the occurrence, quality, quantity, and availability of mineral resources vital to the economy and national security. The USGS, through its National Minerals Information Center (NMIC), collects, analyzes, and disseminates information on more than 90 nonfuel mineral commodities from more than 180 countries. This fact sheet provides information on the production, consumption, supply chain, geology, and resource availability of beryllium in a global context.

Full Text Available Mineral resources represent an important natural resource whose exploitation, unless it is rational, can lead to their exhaustion and the collapse of sustainable development. Given the importance of mineral resources and the uncertainty concerning the estimation of extant reserves, they have been analyzed by several national and international institutions. In this article we shall present a few aspects concerning the ways to approach the reserves of mineral resources at national and international level, by considering both economic aspects and those aspects concerned with the definition, classification and aggregation of the reserves of mineral resources by various specialized institutions. At present there are attempts to homogenize practices concerning these aspects for the purpose of presenting correct and comparable information.

Survey and critique of quantitative methods for the appraisal of mineral resources. Progress report

International Nuclear Information System (INIS)

Harris, D.P.

1976-01-01

Two major categories of appraisal methods (models) for regional mineral resources are identified by virtue of the manner in which mineral endowment is treated in the appraisal: implicit and explicit models. Implicit models do not identify nor specify the mineral endowment model. Mineral resources are inferred to exist as required to fulfill economic or secular relationships. Econometric models of mineral supply and Hubbert's time-rate trend projection are varieties of implicit models. Explicit mineral resource models separate the economic and endowment models and state the endowment model explicitly. Explicit models describe mineral endowment as a function of some physical aspect of the earth's crust, such as geology, volume of rock, density of mineral occurrences, and crustal abundance of an element. Economic factors are introduced subsequent to the appraisal of endowment either as an explicit model which interacts with the deposits inferred by the endowment model, or as a simple adjustment made directly on some aggregate measure of endowment

Indonesia archipelago have the very complex geo diversity. The complexity of geo diversity gives a lot of opportunity on exploiting of earth resources for society prosperity. In other side, the complexity of geology also gives a lot of resistance and various limitation at one particular region to expand. Hence, various data of geology as well as data of result of mapping of minerals resources (mapping at macro scale and also have detail scale) require to be managed and exploited maximally. Effort the exploiting also require various infrastructure which is concerning regulatory, technological, human resources being, market-drive of an economic geo material, social environment and culture which grow around geology data, and also availability and readiness of geology and mineral resources data. This study is expected can give a few description of how the geology and minerals resources data can be as reference in regional development planning. This paper was writed by assessment of description qualitative and comparative inter-region case study in various regency area, where writer have been involved to conduct the activity of geological mapping and mineral resources data and also involved by a discussion with a few officers of local government in so many opportunity. Some of the case study region for example : in Kampar Regency (Riau), Tanjung Jabung Timur Regency (Jambi), Biak Numfor Regency (Papua), Gunung Kidul Regency (Yogyakarta), Pacitan Regency (East Java), and also Klaten Regency (Central Java).

The Morey (NV-060-191) and Fandango (NV-060-190) Wilderness Study Areas are located in the northern Hot Creek Range about 25 mi north of Warm Springs, Nev. At the request of the Bureau of Land Management, 46,300 acres of the Morey and Fandango Wilderness Study Areas were studied. In this report, the area studied is referred to as 'the wilderness study area', or simply 'the study area'. Geologic, geochemical, geophysical, and mineral surveys were conducted by the USGS and the USBM in 1984 to appraise the identified mineral resources and to assess the mineral resource potential of the study areas. These studies indicate that there are small identified resources of zinc, lead, and silver at the Lead Pipe property in the Fandango Wilderness Study Area, several areas of high potential for the occurrence of gold resources in the Fandango study area, small areas of low and moderate potential for the occurrence of silver, lead, and zinc resources in the Fandango study area, areas of moderate and high potential for the occurrence of silver, lead, and zinc resources in the Morey study area, and an area of low potential for copper, molybdenum, and tin in the Morey study area. Both study areas have low resource potential for petroleum, natural gas, uranium, and geothermal energy.

The world's use of nonfuel mineral resources continues to increase to support a growing population and increasing standards of living. The ability to meet this increasing demand is affected especially by concerns about possible environmental degradation associated with minerals production and by competing land uses. What information does the world need to support global minerals development in a sustainable way?Informed planning and decisions concerning sustainability and future mineral resource supply require a long–term perspective and an integrated approach to resource, land use, economic, and environmental management worldwide. Such perspective and approach require unbiased information on the global distribution of identified and especially undiscovered resources, the economic and political factors influencing their development, and the potential environmental consequences of their exploitation.The U.S. Geological Survey and the former Deposit Modeling Program of the International Union of Geological Sciences (IUGS) of the United Nations Educational, Scientific and Cultural Organization (UNESCO) sponsored a workshop on "Deposit Modeling, Mineral Resource Assessment, and Their Role in Sustainable Development" at the 31st International Geological Congress (IGC) in Rio de Janeiro, Brazil, on August 18–19, 2000. The purpose of the workshop was to review the state-of-the-art in mineral deposit modeling and resource assessment and to examine the role of global assessments of nonfuel mineral resources in sustainable development.The workshop addressed questions such as the following: Which of the available mineral deposit models and assessment methods are best suited for predicting the locations, deposit types, and amounts of undiscovered nonfuel mineral resources remaining in the world? What is the availability of global geologic, mineral deposit, and mineral exploration information? How can mineral resource assessments be used to address economic and

Minerals in the environment and products manufactured from mineral materials are all around us and we use and come into contact with them every day. They impact our way of life and the health of all that lives. Minerals are critical to the Nation's economy and knowing where future mineral resources will come from is important for sustaining the Nation's economy and national security. The U.S. Geological Survey (USGS) Mineral Resources Program (MRP) provides scientific information for objective resource assessments and unbiased research results on mineral resource potential, production and consumption statistics, as well as environmental consequences of mining. The MRP conducts this research to provide information needed for land planners and decisionmakers about where mineral commodities are known and suspected in the earth's crust and about the environmental consequences of extracting those commodities. As part of the MRP scientists of the Western Mineral and Environmental Resources Science Center (WMERSC or 'Center' herein) coordinate the development of national, geologic, geochemical, geophysical, and mineral-resource databases and the migration of existing databases to standard models and formats that are available to both internal and external users. The unique expertise developed by Center scientists over many decades in response to mineral-resource-related issues is now in great demand to support applications such as public health research and remediation of environmental hazards that result from mining and mining-related activities. Western Mineral and Environmental Resources Science Center Results of WMERSC research provide timely and unbiased analyses of minerals and inorganic materials to (1) improve stewardship of public lands and resources; (2) support national and international economic and security policies; (3) sustain prosperity and improve our quality of life; and (4) protect and improve public health, safety, and environmental quality.

Trends in global mineral production and expanding uses of mineral resources foretell a bright future, although with significant challenges, for exploration and development. Demand for mineral resources is likely to remain high and grow to meet increases in world population and standards of living. Significant challenges include meeting future demand with new discoveries and developing the resources in environmentally, socially, and economically sustainable ways. A historical perspective from the last 50 years on finding new mineral districts, discovering new types of ore deposits, and using new technologies in exploration suggests that the world will not run out of mineral resources. It is likely that substitution and recycling will play increasingly major roles in meeting global mineral demand. New technologies for ocean mining will help add to the resource base. Historical perspectives also suggest that mining scams will continue, and environmental, health, and safety concerns will be major factors in deciding where future mines will be located and how they will be operated.

Quantifying exhaustible resource theory: an application to mineral taxation policy

Ward, F.A.; Kerkvliet, J.

1993-01-01

The paper presents the results of a dynamic nonlinear programming model of a mineral resource market with several features of heterogeneous quality in the mineral, links with related product markets, incorporation of institutional constraints, resource allocations for each year in the planning period, and analysis of outcomes under various severance tax rates. The model computes privately efficient competitive use paths to perform cost-benefit analysis of public mineral policies. Policy variables are evaluated for their impact on both private behaviour and public benefits. The application is to New Mexico's linked coal and electric power markets. Findings reveal that scarcity rents are currently 4% of coal's price, and peak at 27% in 43 years. Increasing the present 1 dollar/ton New Mexico severance tax to 11 dollars reduces current annual coal output by 25%, prolongs the life of the state's coal industry by three years, and increases discounted severance tax revenues by 850% or 4.2 billion dollars. 38 refs., 2 figs., 4 tabs

Investigations needed to stimulate the development of Jordan's mineral resources

The level of living that any society can attain is a direct function of the use it makes of all kinds of raw materials (soil, water, metals, nonmetals, etc.), all kinds of energy (both animate and inanimate), and all kinds of human ingenuity; and is an inverse function of the size of the population that must share the collective product. The relation between raw materials, energy and ingenuity is such that use of a large amount of one may offset the need for large amounts of others. The most vital raw materials are water, soil, and construction materials, for these are needed in large quantities and are hard to import. Metals, chemicals, and inanimate energy are necessary for industrialization. The more of these minerals a nation possess, the better, but not nation can hope to be self-sufficient in all of the m and therefore must trade for some essential materials. Jordan’s natural resources have been little explored. The grantitc-metamorphic terrane in the southeastern part of the Kingdom could contain deposits of tungsten, rare earths, feldspar, mica, fluorite etc. and the sedimentary terrane over much of the rest of the county is favorable for the occurrence of oil. Even if none of these minerals is found, however, Jordan’s other mineral resource, if fully explored and developed in the light of modern technology, will support a far higher level of living than her people now enjoy. Very likely she can increase her rainfall by about 10 percent by cloud seeding, and she undeveloped supplies in both surface and ground water that are sufficient to nearly double her usable water supply. Even if she does not have oil or have it in large quantities, she can buy it cheaply from neighboring counties, and in addition has undeveloped sources of hydroelectric power, large reserves of bituminous limestone, large reserves of nuclear power as uranium in phosphate rock, and can use solar and wind power for special purposes. Her large supplies of construction, fertilizer, and

Bush, Alfred L.; Condon, Steven M.; Franczyk, Karen J.; Brown, S.Don

1983-01-01

The mineral resource potential of the Piedra Wilderness Study Area is low. No occurrences of metallic minerals, of valuable industrial rocks and minerals, or of useful concentrations of organic fuels are known in the study area. However, a noneconomic occurrence of gypsum in the Jurassic Wanakah Formation lies a few hundred feet west of the WSA boundary, is believed to extend into the WSA, and has a low resource potential. Particular attention was paid to the possible occurrence of organic fuels in the Pennsylvanian Hermosa Formation, of uranium and vanadium in the Jurassic Entrada Sandstone and Morrison Formation, and of coal in the Cretaceous Dakota Sandstone. Thin coaly beds in the Dakota have a low resource potential. Extensive sampling of stream sediments, limited sampling of rock outcrops and springs, and a number of scintillometer traverses failed to pinpoint significant anomalies that might be clues to mineral deposits.

The Swasey Mountain and the Howell Peak Wilderness Study Areas are underlain by an east-dipping sequence of carbonate rocks, shale, and quartzite of Cambrian age. The Sand Pass mineralized area, immediately northwest of the Swasey Mountain Wilderness Study Area, contains numerous occurrences of jasperoid, small igneous intrusions of Tertiary age, and geochemical anomalies; the mineralized area has been explored for gold. Although no identified resources of metals are known in or near the wilderness study areas, the distribution of geologic structures and stream-sediment geochemical anomalies indicates there is a moderate potential for undiscovered resources of lead, zinc, copper, molybdenum, silver, and gold. An area of moderate potential for undiscovered resources of these metals extends south and east into the Swasey Mountain Wilderness Study Area from the Sand Pass mineralized area. A second area of moderate potential for undiscovered resources of these metals extends from the southern part of the Swasey Mountain Wilderness Study Area across the western part of the Howell Peak Wilderness Study Area. Both study areas contain inferred subeconomic resources of quartzite, high-purity limestone, and sand and gravel. Both areas have moderate resource potential for high-purity limestone and dolomite. Fossils, especially trilobites, of interest to collectors are present in both areas. The potential for undiscovered resources is moderate for oil and gas and is low for geothermal energy within the study areas. There is no potential for undiscovered resources of coal.

Natural resource planning at all scales demands methods for assessing the impacts of resource development and use, and in particular it requires standardized methods that yield robust and unbiased results. Building from existing probabilistic methods for assessing the volumes of energy and mineral resources, we provide an algorithm for consistent, reproducible, quantitative assessment of resource development impacts. The approach combines probabilistic input data with Monte Carlo statistical methods to determine probabilistic outputs that convey the uncertainties inherent in the data. For example, one can utilize our algorithm to combine data from a natural gas resource assessment with maps of sage grouse leks and piñon-juniper woodlands in the same area to estimate possible future habitat impacts due to possible future gas development. As another example: one could combine geochemical data and maps of lynx habitat with data from a mineral deposit assessment in the same area to determine possible future mining impacts on water resources and lynx habitat. The approach can be applied to a broad range of positive and negative resource development impacts, such as water quantity or quality, economic benefits, or air quality, limited only by the availability of necessary input data and quantified relationships among geologic resources, development alternatives, and impacts. The framework enables quantitative evaluation of the trade-offs inherent in resource management decision-making, including cumulative impacts, to address societal concerns and policy aspects of resource development.

Critical Minerals and Energy–Impacts and Limitations of Moving to Unconventional Resources

Directory of Open Access Journals (Sweden)

Benjamin C. McLellan

2016-05-01

Full Text Available The nexus of minerals and energy becomes ever more important as the economic growth and development of countries in the global South accelerates and the needs of new energy technologies expand, while at the same time various important minerals are declining in grade and available reserves from conventional mining. Unconventional resources in the form of deep ocean deposits and urban ores are being widely examined, although exploitation is still limited. This paper examines some of the implications of the transition towards cleaner energy futures in parallel with the shifts through conventional ore decline and the uptake of unconventional mineral resources. Three energy scenarios, each with three levels of uptake of renewable energy, are assessed for the potential of critical minerals to restrict growth under 12 alternative mineral supply patterns. Under steady material intensities per unit of capacity, the study indicates that selenium, indium and tellurium could be barriers in the expansion of thin-film photovoltaics, while neodymium and dysprosium may delay the propagation of wind power. For fuel cells, no restrictions are observed.

The paper sets forth a theoretical framework for the strategy of the radically new stage in development of geotechnologies under conditions of rapidly aggravating environmental crisis of the contemporary technocratic civilization that utilizes the substance extracted from the lithosphere as the source of energy and materials. The authors of the paper see the opportunity to overcome the conflict between the techno- and bio-spheres in the area of mineral raw materials by means of changing the technological paradigm of integrated mineral development by implementing nature-like technologies oriented to the ideas and methods of converging resources of natural biota as the object of the environmental protection and geotechnologies as the major source of ecological hazards induced in the course of development of mineral resources of lithosphere.

Development policy of overseas resources of Korea should be carried out as a part of long-term resources security policy that can prepare for the stable supply and demand of needed resources under the proper economic size and industrial structure. This study tried to search for the ways to promote overseas development of bituminous coal and, general mineral resources, and support them more effectively per field. For this, development achievements so far, domestic and foreign pending issues, and operation status of the support system are studied, analyzed, and the improvement plans are drafted per field. Financial support for overseas resources development should be more expanded than the present in the future. For this, the current collateral system centered on real right should be improved and financial support centered on the credit of enterprise should be reinforced. Besides, in the related tax support system, related tax laws and systems should be improved in order to alleviate the tax burden of business operators so that they can carry out the overseas resources development business with more advantageous conditions through the additive introduction of current deduction system of indirect payment tax. Since payback period of overseas resources development business tends to become long-term, it should be continuously carried out based on future-oriented development investment plan and will of more than twenty (20) years rather than on temporary development support plan based on short-term market trend. 25 refs., 73 tabs.

Full Text Available The author, due to the didactic needs and seeing a small gap in the way of presenting scientific data on the area of social science, have decided to present this work hoping that it will influence on widening both the social science and geography knowledge of the recipients, having connected the development and creation of certain social phenomena with particular economic activity, that is, the extraction of mineral resources. The aim of the hereby text is to present such social phenomena like organizational culture, discourse and social capital. The notions mentioned above ought to concern not only students, but also the specialists and scientists dealing with any of those two fields, as it seems prudent to follow the path of closely connecting two major issues emerging from two distinctively separate areas of science if that may help to better understand how such mixture influence people’s behaviour and allows to draw conclusion on the effect such actions may have on community or society. Moreover, such fact was prior for the author to decide to work on the problem of protests for mining in the future. On the other hand, the article may help in organizing the process of exploitation of mineral resources in the different organizations involved in this type of activity.

International standardisation for the reporting of Mineral Resources and Ore Reserves

Farmer, Karilyn

2014-01-01

The mining industry is a vital contributor to national and global economies. It is a truly international business that depends on the trust and confidence of investors and other stakeholders for its financial and operational well-being. Unlike many other industries, it is based on depleting mineral assets, the knowledge of which is imperfect prior to the commencement of extraction. It is therefore essential that the industry communicates the risks associated with investment effectively and transparently in order to earn the level of trust necessary to underpin its activities. Enforceable mineral resource and mineral (Ore) reserves codes are critical to earning this confidence.

Mineral resource assessments integrate and synthesize available information as a basis for estimating the location, quality, and quantity of undiscovered mineral resources. This probabilistic mineral resource assessment of undiscovered sandstone copper deposits within Paleoproterozoic metasedimentary rocks of the Kodar-Udokan area in Russia is a contribution to a global assessment led by the U.S. Geological Survey (USGS). The purposes of this study are to (1) delineate permissive areas (tracts) to indicate where undiscovered sandstone-hosted copper deposits may occur within 2 km of the surface, (2) provide a database of known sandstone copper deposits and significant prospects, (3) estimate numbers of undiscovered deposits within these permissive tracts at several levels of confidence, and (4) provide probabilistic estimates of amounts of copper (Cu) and mineralized rock that could be contained in undiscovered deposits within each tract. The workshop for the assessment, held in October 2009, used a three-part form of mineral resource assessment as described by Singer (1993) and Singer and Menzie (2010).

Multivariate statistical analyses were carried out on Hydrogeochemical and Stream Sediment Reconnaissance data from the Craig quadrangle, Colorado, to support the National Uranium Resource Evaluation and to evaluate strategic or other important commercial mineral resources. A few areas for favorable uranium mineralization are suggested for parts of the Wyoming Basin, Park Range, and Gore Range. Six potential source rocks for uranium are postulated based on factor score mapping. Vanadium in stream sediments is suggested as a pathfinder for carnotite-type mineralization. A probable northwest trend of lead-zinc-copper mineralization associated with Tertiary intrusions is suggested. A few locations are mapped where copper is associated with cobalt. Concentrations of placer sands containing rare earth elements, probably of commercial value, are indicated for parts of the Sand Wash Basin

Despite the history of the Semipalatinsk test site in nuclear weapons testing, this territory is of interest for geologic exploration and utilization of mineral resources. The prospect for minerals on this territory was already known before the beginning of tests. Nowadays several companies work on the territory. Positive experience of using Kara Zhira coal deposit, refinement of local gabbros and stone-cutting plant, and preparation of gold mining at Naimanzhal deposit, allow us to hope that these mineral and raw material resources of the Semipalatinsk test site can become an important economic factor for development of the Eastern Kazakhstan region.

Sustainable development and the exploitation of mineral and energy resources: a review

Science.gov (United States)

Wellmer, F.-W.; Becker-Platen, J. D.

2002-04-01

Natural resources, e.g., metals, industrial minerals, water, and soil, are the essential basis for our economy and well-being. We have to know where these raw materials come from and how they are mined. Sustainable development requires the maintenance, rational use and enhancement of natural resources, as well as a balanced consideration of ecology, economy and social justice. Four general rules concerning the implementation of sustainable development for renewable and non-renewable resources are discussed. Examples of the consumption of selected materials from historical times to the present day are presented, as well as of regional distribution, usage (in contrast to consumption), lifetimes of resources, the supply-and-demand cycle, recycling and substitution in modern times. To fulfill the requirement of sustainable development, the efficiency with which resources are utilized has to be improved. The learning process, often driven by financial rewards, leads from one technology to a better one, thus increasing the efficiency of the use of a resource or commodity. Examples of learning curves are discussed. Industrial countries have to transfer their advanced technologies to developing countries in order to avoid undesirable development in the mining industry and use of natural resources in those regions. The use of the best available technology by the mining industry, taking into account economic considerations, and the necessity to establish environmental guidelines are essential if environmental impact of the production of non-renewable resources is to be minimized. Far more critical than the production of non-renewable resources under the aspect of sustainable development and the capacity of the pollutant sinks of the Earth is the element of natural attenuation with regard to the resources soil and water.

The seabed - an important mineral resource of Slovakia in the future

Directory of Open Access Journals (Sweden)

Peter Blišťan

Full Text Available In 1987, Slovakia bought part of the ocean bottom with the occurrence of mineral resources future - polymetallic nodules. The polymetallic nodule is a geological term for naming natural features consisting of more than 40 metals and other chemical elements. These special services originated in the ocean for two to three million years and nowadays, they are of main interest for countries whose mineral wealth is little or no available. Nodules contain about 30 % manganese, 1.2 % copper, 1.2 % nickel, 0.2 % cobalt, rare earth elements, etc. The existence of submarine nodules was found by the British ship HMS "Challenger" by oceanographic research in 1872 - 1876. Research and the subsequent mining of nodules were particularly points of interest for Western countries as well as the USSR. Rules for the use of mineral resources of the seabed beyond the limits of national jurisdiction were codified in the Convention on the Law of 1982, which came into force on 16.11.1994, and in the Slovakia on 21.7.1996. The seabed is one of the international space next to the high seas, Antarctica, outer space and celestial bodies, which are not subject to the sovereignty of any state authority.

SummaryMineral commodities are vital for economic growth, improving the quality of life, providing for national defense, and the overall functioning of modern society. Minerals are being used in larger quantities than ever before and in an increasingly diverse range of applications. With the increasing demand for a considerably more diverse suite of mineral commodities has come renewed recognition that competition and conflict over mineral resources can pose significant risks to the manufacturing industries that depend on them. In addition, production of many mineral commodities has become concentrated in relatively few countries (for example, tungsten, rare-earth elements, and antimony in China; niobium in Brazil; and platinum-group elements in South Africa and Russia), thus increasing the risk for supply disruption owing to political, social, or other factors. At the same time, an increasing awareness of and sensitivity to potential environmental and health issues caused by the mining and processing of many mineral commodities may place additional restrictions on mineral supplies. These factors have led a number of Governments, including the Government of the United States, to attempt to identify those mineral commodities that are viewed as most “critical” to the national economy and (or) security if supplies should be curtailed.This book presents resource and geologic information on the following 23 mineral commodities currently among those viewed as important to the national economy and national security of the United States: antimony (Sb), barite (barium, Ba), beryllium (Be), cobalt (Co), fluorite or fluorspar (fluorine, F), gallium (Ga), germanium (Ge), graphite (carbon, C), hafnium (Hf), indium (In), lithium (Li), manganese (Mn), niobium (Nb), platinum-group elements (PGE), rare-earth elements (REE), rhenium (Re), selenium (Se), tantalum (Ta), tellurium (Te), tin (Sn), titanium (Ti), vanadium (V), and zirconium (Zr). For a number of these commodities�

Geologic, geochemical, and geophysical studies within the Raywood "Flat Roadless Areas, together with an investigation of mines and prospects within the further planning area, resulted in (1) identification of nonmetallic mineral resources at a marble mine in the further planning area and (2) recognition of a small area in the recommended wilderness that has moderate potential for base-metal resources. Except for these two areas of identified and suspected resources, we did not observe indications of resource potential elsewhere in the Raywood Flat Roadless Areas.

Australia's uranium resources amount to 29% of the WOCA countries (world outside centrally-planned-economies areas) low-cost Reasonably Assured Resources and 28% of the WOCA countries low-cost Estimated Additional Resources. As at 1 January 1986, the Bureau of Mineral Resources estimated Australia's uranium resources as: (1) Cost range to US$80/kg U -Reasonably Assured Resources, 465 000 t U; Estimated Additional Resources, 256 000 t U; (2) Cost range US$80-130/kg U -Reasonably Assured Resources, 56 000 t U; Estimated Additional Resources, 127 000 t U. Most resources are contained in Proterozoic unconformity-related deposits in the Alligator Rivers uranium field in the Northern Territory (Jabiluka, Ranger, Koongarra, Nabarlek deposits) and the Proterozoic stratabound deposit at Olympic Dam on the Stuart Shelf in South Australia

The actual status of uranium ore resources at Eko Remaja Sector: the need of verification of resources computation and geometrical form of mineralization zone by mining test

Johan Baratha; Muljono, D.S.; Agus Sumaryanto; Handoko Supalal

1996-01-01

Uranium ore resources calculation was done after ending all of geological work step. Estimation process of ore resources was started from evaluation drilling, continued with borehole logging. From logging, the result has presented in anomaly graphs, then was processed to determine thickness and grade value of ore. Those mineralization points were correlated one another to form mineralization zones which have direction of N 270 degree to N 285 degree with 70 degree dip to North. From Grouping the mineralization distribution, 19 mineralization planes was constructed which contain 553 ton of U 3 O 8 measured. It is suggested that before expanding measured ore deposit area, mining test should be done first at certain mineralization planes to prove the method applied to calculate the reserve. Results form mining test could be very useful to reevaluate all the work-step done. (author); 4 refs; 2 tabs; 8 figs

Geology and undiscovered resource assessment of the potash-bearing Central Asia Salt Basin, Turkmenistan, Uzbekistan, Tajikistan, and Afghanistan: Chapter AA in Global mineral resource assessment

Wynn, Jeff; Orris, Greta J.; Dunlap, Pamela; Cocker, Mark D.; Bliss, James D.

2016-03-23

Undiscovered potash resources in the Central Asia Salt Basin (CASB) of Turkmenistan, Uzbekistan, Tajikistan, and Afghanistan were assessed as part of a global mineral resource assessment led by the U.S. Geological Survey. The term “potash” refers to potassium-bearing, water-soluble salts derived from evaporite basins, where seawater dried up and precipitated various salt compounds; the word for the element “potassium” is derived from potash. Potash is produced worldwide at amounts exceeding 30 million metric tons per year, mostly for use in fertilizers. The term “potash” is used by industry to refer to potassium chloride, as well as potassium in sulfate, nitrate, and oxide forms. For the purposes of this assessment, the term “potash” refers to potassium ores and minerals and potash ore grades. Resource and production values are usually expressed by industry in terms of K2O (potassium oxide) or muriate of potash (KCl, potassium chloride).

Effective resource management in a globalizing economy requires accurate assessments of fossil energy and minerals resources. The recoverable quantities must be described and categorized in a manner that is consistent with scientific and social/economic information describing the economy as well as with the information describing the projects to recover them. A number of different standards have evolved over time in response to various professional needs Under a mandate given by the United Nations Economic and Social Council, the United Nations Economic Commission for Europe (UNECE) has cooperated with Governments, regulatory agencies, industry, international organizations, and professional organizations (including Committee for Mineral Reserves International Reporting Standards (CRIRSCO), the Society of Petroleum Engineers (SPE), the American Association of Petroleum Geologists (AAPG), and the Society of Petroleum Evaluation Engineers (SPEE)), as well as with outstanding experts, to define a global classification for extractive activities (including oil, gas, heavy oil and bitumen extraction) that reflects the principal concerns of existing petroleum and mineral classifications. The United Nations Framework Classification for Fossil Energy and Mineral Reserves and Resources-2009 (UNFC-2009) aims to serve the following four principal needs: 1. The needs in international energy and mineral studies to formulate robust and long-sighted policies. 2. The needs of governments in managing their resources accordingly, allowing market prices to be transferred to the wellhead with as little loss as possible. 3. The industries' needs for information while deploying technology, management and finance to secure energy supplies and capture value efficiently within the established frameworks to serve its host countries, shareholders and stakeholders. 4. The financial community's need for information to allocate capital appropriately, providing reduced costs and improved long

1998-01-01

This project incorporates two related research projects directed toward understanding respiratory carcinogenesis in radon-exposed former uranium miners. The first project involved a continuation of the tissue resource of lung cancer cases from former underground uranium miners and comparison cases from non-miners. The second project was a pilot study for a proposed longitudinal study of respiratory carcinogenesis in former uranium miners. The objectives including facilitating the investigation of molecular changes in radon exposed lung cancer cases, developing methods for prospectively studying clinical, cytologic, cytogenetic, and molecular changes in the multi-event process of respiratory carcinogenesis, and assessing the feasibility of recruiting former uranium miners into a longitudinal study that collected multiple biological specimens. A pilot study was conducted to determine whether blood collection, induced sputum, bronchial brushing, washings, and mucosal biopsies from participants at two of the hospitals could be included efficiently. A questionnaire was developed for the extended study and all protocols for specimen collection and tissue handling were completed. Resource utilization is in progress at ITRI and the methods have been developed to study molecular and cellular changes in exfoliated cells contained in sputum as well as susceptibility factors

An Analysis of the Published Mineral Resource Estimates of the Haji-Gak Iron Deposit, Afghanistan

International Nuclear Information System (INIS)

Sutphin, David M.; Renaud, Karine M.; Drew, Lawrence J.

2011-01-01

The Haji-Gak iron deposit of eastern Bamyan Province, eastern Afghanistan, was studied extensively and resource calculations were made in the 1960s by Afghan and Russian geologists. Recalculation of the resource estimates verifies the original estimates for categories A (in-place resources known in detail), B (in-place resources known in moderate detail), and C 1 (in-place resources estimated on sparse data), totaling 110.8 Mt, or about 6% of the resources as being supportable for the methods used in the 1960s. C 2 (based on a loose exploration grid with little data) resources are based on one ore grade from one drill hole, and P 2 (prognosis) resources are based on field observations, field measurements, and an ore grade derived from averaging grades from three better sampled ore bodies. C 2 and P 2 resources are 1,659.1 Mt or about 94% of the total resources in the deposit. The vast P 2 resources have not been drilled or sampled to confirm their extent or quality. The purpose of this article is to independently evaluate the resources of the Haji-Gak iron deposit by using the available geologic and mineral resource information including geologic maps and cross sections, sampling data, and the analog-estimating techniques of the 1960s to determine the size and tenor of the deposit.

Mineral resources

This paper reports that to prevent the concentration of control over federal oil and gas resources in a few companies or individuals, Congress has limited the number of acres of oil and gas leases that one party may control in a single state. An exception to this limitation involves lease acreage within the boundaries of development contracts. These contracts permit oil and gas lease operators and pipeline companies to contract with enough lessees to economically justify large-scale drilling operations for the production and transportation of oil and gas, subject to approval by the Secretary of the Interior, who must find that such contracts are in the public interest. Since 1986 Interior has entered into or approved 10 contracts with 12 lease operators for exploration of largely unleased federal lands-ranging from about 180,000 to 3.5 million acres in four western states-and has designated them as developmental contracts. GAO believes that the 10 contracts do not satisfy the legal requirements for development contracts because they are for oil and gas exploration on largely unleased federal lands, rather than for developing existing leases. By designating the 10 contracts as development contracts, Interior has enabled nine of the 12 contract parties to accumulate lease acreage that vastly exceeds the statutory acreage limitation. All nine of the contract parties were major or large independent oil companies. As a result, other parties who wish to participate in developing federal oil and gas resources within the four states may be adversely affected because the parties to Interior's contracts have been able to compete for and obtain lease acreage beyond the statutory acreage limitation. Although Interior believes that the Secretary has the discretion under law to use development contracts in the current manner, in April 1989 it ceased issuing these contracts pending completion of GAO's review

2012-01-01

Emerging green technologies are the most significant and realistic path to reducing global dependence on polluting fossil fuels while simultaneously decreasing the reliance of many countries on oil-rich regimes to meet their energy needs. However, as nations begin to rely on green energy products, they are trading one set of resource dependencies for another. Wind and sun produce energy, but rare minerals like neodymium and tellurium are essential in applications to harness that power. To the...

This book provides an analysis of the issues surrounding international resources and inspiring accounts of industrial best practices. The book consists of two distinct parts. The first part of the book brings together the results of years of research into the geopolitical, economic and ecological dimensions of material scarcity and resource efficiency. Chapter 2 discusses the main challenges and constraints related to the use of energy resources, water and land, industrial and metallic minerals, construction minerals and biotic resources, including water use and ecosystem degradation. The chapter also addresses important linkages between these various resources. Chapter 3 describes the international trends that are shaping the geopolitics of natural resources and looks at the implications for Europe and the Netherlands. Chapter 4 presents a wide range of strategies by which governments, producers and consumers may contribute to the more sustainable use of natural resources. The second part of the book describes 21 inspiring best practices in resource efficiency in a variety of industrial sectors. Based on a series of interviews with industrial pioneers, these chapters relate their first-hand experiences in improving resource efficiency. These business cases demonstrate that innovation and entrepreneurship can result in substantial improvements in resource efficiency. Chapter 5 focuses on best practices in the built environment, where substantial amounts of energy and minerals are used. Chapter 6 presents four ambitious strategies to promote sustainable food production and consumption. Chapter 7 describes recent developments in the chemical process industry, which produces most of the ingredients, compounds and semi-products for the vast range of products used by society. Chapter 8 provides four examples of the state-of-the-art in resource efficiency in the metal and high-tech industries. This chapter presents four business cases highlighting the benefits of the

The mineral resource implications of an economy of tokamak-type fusion reactors are assessed based upon the recent conceptual reactor design study, NUWMAK, developed at the University of Wisconsin. For comparative purposes, various structural alloys of vanadium and steel are assumed to be usable in the NUWMAK design in place of the titanium alloy originally selected. In addition, the inner blanket core and magnet system of the conceptual reactor, HFCTR, developed at the Massachusetts Institute of Technology, are assumed to be interchangeable with the comparable components in NUWMAK. These variations permit a range of likely requirements to be assessed.

2012-01-01

The U.S. Geological Survey collaborated with the China Geological Survey to conduct a mineral-resource assessment of resources in porphyry copper deposits on the Tibetan Plateau in western China. This area hosts several very large porphyry deposits, exemplified by the Yulong and Qulong deposits, each containing at least 7,000,000 metric tons (t) of copper. However, large parts of the area are underexplored and are likely to contain undiscovered porphyry copper deposits.

Church, S.E.; Riehle, J.R.; Magoon, L.B.; Campbell, D.L.

1992-01-01

On the basis of new geologic mapping and exploration geochemical studies, we have provided a mineral and energy resource assessment of the Mount Katmai, Naknek, and western Afognak quadrangles, Alaska. We delineate four tracts of ground that have metallic mineral resources. The mineral deposit types considered in each tract are summarized in table 4. Estimates of the number of undiscovered mineral deposits have been made for porphyry copper and polymetallic vein deposits. We estimate that one undiscovered porphyry copper deposit is present in the Katmai study area at the ten percent probability level. Although the sampling density may be too low to give an accurate estimate of the number of undiscovered polymetallic vein deposits, we suggest that, at a minimum, there is a five percent probability for five or more undiscovered polymetallic vein deposits in the Katmai study area. In addition, several areas have potential for undiscovered porphyry molybdenum, massive sulfide, and epithermal gold and mercury deposits.

Active Learning Techniques Applied to an Interdisciplinary Mineral Resources Course.

Science.gov (United States)

Aird, H. M.

2015-12-01

An interdisciplinary active learning course was introduced at the University of Puget Sound entitled 'Mineral Resources and the Environment'. Various formative assessment and active learning techniques that have been effective in other courses were adapted and implemented to improve student learning, increase retention and broaden knowledge and understanding of course material. This was an elective course targeted towards upper-level undergraduate geology and environmental majors. The course provided an introduction to the mineral resources industry, discussing geological, environmental, societal and economic aspects, legislation and the processes involved in exploration, extraction, processing, reclamation/remediation and recycling of products. Lectures and associated weekly labs were linked in subject matter; relevant readings from the recent scientific literature were assigned and discussed in the second lecture of the week. Peer-based learning was facilitated through weekly reading assignments with peer-led discussions and through group research projects, in addition to in-class exercises such as debates. Writing and research skills were developed through student groups designing, carrying out and reporting on their own semester-long research projects around the lasting effects of the historical Ruston Smelter on the biology and water systems of Tacoma. The writing of their mini grant proposals and final project reports was carried out in stages to allow for feedback before the deadline. Speakers from industry were invited to share their specialist knowledge as guest lecturers, and students were encouraged to interact with them, with a view to employment opportunities. Formative assessment techniques included jigsaw exercises, gallery walks, placemat surveys, think pair share and take-home point summaries. Summative assessment included discussion leadership, exams, homeworks, group projects, in-class exercises, field trips, and pre-discussion reading exercises

NATURAL RESOURCES ASSESSMENT

D.F. Fenster

2000-01-01

The purpose of this report is to summarize the scientific work that was performed to evaluate and assess the occurrence and economic potential of natural resources within the geologic setting of the Yucca Mountain area. The extent of the regional areas of investigation for each commodity differs and those areas are described in more detail in the major subsections of this report. Natural resource assessments have focused on an area defined as the ''conceptual controlled area'' because of the requirements contained in the U.S. Nuclear Regulatory Commission Regulation, 10 CFR Part 60, to define long-term boundaries for potential radionuclide releases. New requirements (proposed 10 CFR Part 63 [Dyer 1999]) have obviated the need for defining such an area. However, for the purposes of this report, the area being discussed, in most cases, is the previously defined ''conceptual controlled area'', now renamed the ''natural resources site study area'' for this report (shown on Figure 1). Resource potential can be difficult to assess because it is dependent upon many factors, including economics (demand, supply, cost), the potential discovery of new uses for resources, or the potential discovery of synthetics to replace natural resource use. The evaluations summarized are based on present-day use and economic potential of the resources. The objective of this report is to summarize the existing reports and information for the Yucca Mountain area on: (1) Metallic mineral and mined energy resources (such as gold, silver, etc., including uranium); (2) Industrial rocks and minerals (such as sand, gravel, building stone, etc.); (3) Hydrocarbons (including oil, natural gas, tar sands, oil shales, and coal); and (4) Geothermal resources. Groundwater is present at the Yucca Mountain site at depths ranging from 500 to 750 m (about 1,600 to 2,500 ft) below the ground surface. Groundwater resources are not discussed in this report, but are planned to be included in the hydrology

Mineral resources accounting: A technique formonitoring the Philippine mining industry for sustainable development

Science.gov (United States)

Santos, Teodoro M.; Zaratan, May L.

Mining which extracts exhaustible mineral resources has been condemned by certain sectors as promoting social inequity and underdevelopment. This is so because once a tonne of copper, say, is mined it is forever lost to the future generation. Such perception translates into policies that are usually disadvantageous or even hostile to the industry. Despite this adverse criticism, recent developments in natural resources accounting indicate that mining can truly contribute to the sustainable economic development of a society. True worth of mining in economic development can be assessed and monitored on a continuing basis through an appropriate system of natural accounts (SNA). If the industry is found deficient, such SNA can also point out how the industry can be made to constribute to sustainable growth. The prevailing SNA is criticized as having failed to capture the adverse effects on the welfare of society of producing a nonrenewable resource such as minerals. For instance, the production of copper for a particular year registers an increase in gross national product equivalent to its monetary value. However, the concomitant depletion of the country's natural wealth due to such production is nowhere recorded in the SNA. This faulty accounting gives rise to policies that result in nonsustainable economic growth. In order to address the preceding problem, this paper presents an accounting formula applicable to any nonrenewable resource whereby revenue is decomposed into income and capital components. To achieve sustainable economic growth, it states that the capital component must be invested to generate future incomes. However, investments need not be confined to the same sector. Application of the accounting scheme to the Philippine copper and gold sectors during the 1980-1990 period leads to the following conclusions: (a) by and large, gold and copper mining operations have indeed contributed positively to national income, contrary to allegations of certain

This is the Web version of a CD-ROM publication. This report consists of summary major compilations and syntheses accomplished in the six-year project through April 2003 for the study on the Mineral Resources, Metallogenesis, and Tectonics of Northeast Asia (Eastern and Southern Siberia, Mongolia, Northeastern China, South Korea, and Japan). The major scientific goals and benefits of the project are to: (1) provide a comprehensive international data base on the mineral resources of the region that is the first, extensive knowledge available in English; (2) provide major new interpretations of the origin and crustal evolution of mineralizing systems and their host rocks, thereby enabling enhanced, broad-scale tectonic reconstructions and interpretations; and (3) promote trade and scientific and technical exchanges between the North America and Northeast Asia. Data from the project are providing sound scientific data and interpretations for commercial firms, governmental agencies, universities, and individuals that are developing new ventures and studies in the project area, and for land-use planning studies that deal with both mineral potential issues. Northeast Asia has vast potential for known and undiscovered mineral deposits; however, little information existed in English in the West until publication of products from this project. Consequently, data and interpretations from the project are providing basic knowledge for major scientific, commercial, national, and international endeavors by other interested individuals and groups.

The prospects of the integrated processing of the high-parameter geothermal resources of the East Ciscaucasia of artesian basin (ECAB) with the conversion of their heat energy into electric energy at a binary geoPP and the subsequent extraction of solved chemical compounds from thermal waters are evaluated. The most promising areas for the exploration such resources are overviewed. The integrated exploration of hightemperature hydrogeothermal brines is a new trend in geothermal power engineering, which can make it possible to significantly increase the production volume of hydrogeothermal resources and develop the geothermal field at a higher level with the realization of the energy-efficient advanced technologies. The large-scale exploration of brines can solve the regional problems of energy supply and import substitution and fulfill the need of Russia in food and technical salt and rare elements. The necessity of the primary integrated exploration of the oil-field highly mineralized brines of the South Sukhokumskii group of gas-oil wells of Northern Dagestan was shown in view of the exacerbated environmental problems. Currently, the oil-field brines with the radioactive background exceeding the allowable levels are discharged at disposal fields. The technological solutions for their deactivation and integrated exploration are proposed. The realization of the proposed technological solutions provides 300 t of lithium carbonate, 1650 t of caustic magnesite powder, 27300 t of chemically precipitated chalk, 116100 t of food salt, and up to 1.4 mln m3 of desalinated water from oil-field brines yearly. Desalinated water at the output of a geotechnological complex can be used for different economic needs, which is important for the arid North Caucasus region, where the fresh water deficiency is acute, especially in its plain part within the ECAB.

About 200 rare earth (RE) minerals are distributed in a wide variety of mineral classes, such as halides, carbonates, oxides, phosphates, silicates, etc. Due to the large ionic radii and trivalent oxidation state, RE ions in the minerals have large coordination numbers (c.n.) 6-10 by anions (O, F, OH). Light rare earth elements (LREEs) tend to occupy the larger sites of 8-10 c.n. and concentrate in carbonates and phosphates. On the other hand, heavy rare earth elements (HREEs) and Y occupy 6-8 c.n. sites and are abundant in oxides and a part of phosphates. Only a few mineral species, such as bastnaesite (Ce,La)(CO{sub 3})F, monazite (Ce,La)PO{sub 4}, xenotime YPO{sub 4}, and RE-bearing clay have been recovered for commercial production. Bayan Obo, China is the biggest RE deposit in the world. One of probable hypotheses for ore geneses is that the deposit might be formed by hydrothermal replacement of carbonate rocks of sedimentary origin. The hydrothermal fluid may be derived from an alkaline-carbonatite intrusive series. Following Bayan Obo, more than 550 carbonatite/alkaline complex rocks constitute the majority of the world RE resources. The distribution is restricted to interior and marginal regions of continents, especially Precambrian cratons and shields, or related to large-scale rift structures. Main concentrated areas of the complexes are East African rift zones, northern Scandinavia-Kola peninsula, eastern Canada and southern Brazil. Representative sedimentary deposits of REE are placer- and conglomerate-types. The major potential countries are Australia, India, Brazil, and Malaysia. Weathered residual deposits have been formed under tropical and sub-tropical climates. Bauxite and laterite nickel deposit are the representative. Ion adsorption clay without radioactive elements is known in southern China. Weathering processes concentrate REE in a particular clay mineral-layer in the weathered crusts whose source were originally REE-rich rocks like granite

The purpose of this report is to summarize the scientific work that was performed to evaluate and assess the occurrence and economic potential of natural resources within the geologic setting of the Yucca Mountain area. The extent of the regional areas of investigation for each commodity differs and those areas are described in more detail in the major subsections of this report. Natural resource assessments have focused on an area defined as the ''conceptual controlled area'' because of the requirements contained in the U.S. Nuclear Regulatory Commission Regulation, 10 CFR Part 60, to define long-term boundaries for potential radionuclide releases. New requirements (proposed 10 CFR Part 63 [Dyer 1999]) have obviated the need for defining such an area. However, for the purposes of this report, the area being discussed, in most cases, is the previously defined ''conceptual controlled area'', now renamed the ''natural resources site study area'' for this report (shown on Figure 1). Resource potential can be difficult to assess because it is dependent upon many factors, including economics (demand, supply, cost), the potential discovery of new uses for resources, or the potential discovery of synthetics to replace natural resource use. The evaluations summarized are based on present-day use and economic potential of the resources. The objective of this report is to summarize the existing reports and information for the Yucca Mountain area on: (1) Metallic mineral and mined energy resources (such as gold, silver, etc., including uranium); (2) Industrial rocks and minerals (such as sand, gravel, building stone, etc.); (3) Hydrocarbons (including oil, natural gas, tar sands, oil shales, and coal); and (4) Geothermal resources. Groundwater is present at the Yucca Mountain site at depths ranging from 500 to 750 m (about 1,600 to 2,500 ft) below the ground surface. Groundwater resources are not discussed in this

The U.S. Geological Survey conducted an assessment of resources associated with porphyry copper deposits in the western Central Asia countries of Kyrgyzstan, Uzbekistan, Kazakhstan, and Tajikistan and the southern Urals of Kazakhstan and Russia as part of a global mineral resource assessment. The purpose of the study was to (1) delineate permissive areas (tracts) for undiscovered porphyry copper deposits; (2) compile a database of known porphyry copper deposits and significant prospects; (3) where data permit, estimate numbers of undiscovered deposits within those permissive tracts; and (4) provide probabilistic estimates the amounts of copper (Cu), molybdenum (Mo), gold (Au), and silver (Ag) that could be contained in those undiscovered deposits.

The new UN international framework classification for reserves/resources and its relation to uranium resource classification

International Nuclear Information System (INIS)

Barthel, F.H.; Kelter, D.

2001-01-01

Resources traditionally are classified according to the degree of geological confidence and economic attractiveness. Various names are in use to describe nationally the different resource categories. Commonly, proven, probable or A+B are terms for the category RESERVES, meaning the recoverable portion of a resource under prevailing economic conditions. Since 1965 uranium resources are classified by the Nuclear Energy Agency of OECD and International Atomic Energy Agency using the terms Reasonably Assured Resources (RAR) and Estimated Additional Resources (EAR) in combination with cost categories. The definitions for RAR and EAR have been refined over the time and cost categories have been adapted according to market developments. For practical purposes a comparison of RAR and EAR with major national classification systems is provided in each of the NEA-IAEA publication on 'Uranium Resources Production and Demand' (Red Book). RAR of uranium are defined as quantities recoverable at given production costs with proven mining and processing technology, commonly RAR of the lowest cost category are referred to as Reserves. In 1992 the Committee on Energy - Working Party on Coal of the UN Economic Commission for Europe (UN/ECE) started to develop a new scheme for resource classification under the coordination of one of the authors (Kelter). The main purpose was to create an instrument permitting the classification of reserves and resources on an internationally consistent and uniform basis using market economic criteria. In April 1997 the UN/ECE approved the new 'United Nations International Framework Classification for Reserves/Resources-Solid Fuels and Mineral Commodities' at its 50th Anniversary Session. The new classification will enable the incorporation of national systems into an unified framework in order to make them compatible and comparable. Assistance will be given to economies in transition in reassessing their deposits according to market economy criteria and

1973-01-01

This report summarizes the geology of an area of some 6000 square kilometers in the northern part of the Central Cordillera of the Colombian Andes. The area, in north-central Department of Antioquia, was mapped between 1964 and 1968 as part of the Inventario Minero Nacional (IMN) project. Mineral resources are summarized within a larger area, designated as subzone ILK of IMN Zone If, which comprises almost 22,000 sq. kin, including the area mapped geologically by IMN and additional areas mapped by other agencies. The oldest formation is a micaceous paragneiss of early Paleozoic or possibly late Precambrian age. A thick geosynclinal sedimentary series accumulated during the Paleozoic Era and became regionally metamorphosed to greenschist (locally amphibolite) facies during the Permian or early Triassic; these schists and gneisses are designated collectively as the Valdivia Group. The Permian(?) orogenic episode included intrusion of concordant syntectonic plutons, mostly of tonalitic composition. Rocks of unequivocal Triassic or Jurassic age are not recognized. The Cretaceous is well represented by both igneous and sedimentary assemblages. Eugeosynclinal alpine ophiolites comprising submarine basalt flows and numerous intrusions of gabbro and serpentinite are prominent in the Lower Cretaceous, together with flysch composed of marine shale and lesser sandstone and conglomerate. The Upper Cretaceous is represented along the west border of the mapped area by submarine basalt flows and pyroclastic rocks, locally Interbedded with fine-grained clastic sedimentary beds, and lenses of dark laminated chert, at least part of which is radiolarian. The Late Cretaceous was marked by an orogenic event that profoundly folded and faulted all rocks and in the Central Cordillera caused low-grade metamorphism, the overprint of which is hardly observable in pre-Cretaceous rocks elsewhere. The Late Cretaceous orogeny culminated with discordant intrusion of the epizonal tonalitic

The immaturity of strategic and conceptual documents in the sphere of sustainable development of the Russian economy had a negative impact on long-term strategic forecasting of its neo-industrialization. At the present stage, the problems of overcoming the mineral and raw material dependence, the negative structural shift of the Russian economy, the acceleration of the rates of economic growth, the reduction of technological gap from the developed countries become strategically in demand. The modern structure of the Russian economy, developed within the framework of the proposed market model, does not generate a sustainable type of development. It became obvious that in conditions of the market processes' entropy, without neo-industrial changes, the reconstruction of industry on a new convergence-technological basis and without increasing the share of high technology production the instability of macroeconomic system, the risks of environmental and economic security of Russia are growing. Therefore, today we need a transition from forming one industry development strategy to the national one that will take into account both the social and economic and environmental challenges facing Russia as a mineral resources extracting country.

Resource Areas in the New Institutional Environment

2014-12-01

Full Text Available The article demonstrates that today the dynamics of development and production of mineral resources in resource specializing regions may differ significantly from the canonical scheme - i.e. there is no gradual and steady depletion of natural resources within mentioned territories. The combination of several factors may again move resource regions that used to be «hopeless» to the stage of growing production. These factors are: a modern knowledge economy, an adequate resource mode (norms, rules and procedures that «master» the process of development of natural resources and developed and available infrastructure of mineral resources extraction. As an example the author considers the USA oil-producing states (Texas, Louisiana and North Dakota which showed rapid growth in production of natural gas and oil in the last few years. The author sees the accumulation of a «critical level» of economic activity (infrastructure, the number and diversity of companies in the oil and gas sector and the availability and quality of human capital as the main cause for the development of shale hydrocarbons in these states. These considerations are very important for Russia: the development of heavy oil deposits in Tatarstan, bringing into development the deposits of the Bazhenov formation in Tyumen Oblast and the future oil extraction from bituminous minerals in Yakutia will occur under the same laws (with some Russian specificity, however

Comments on classification of uranium resources

Masters, Charles D.

National resource assessments are intended to give some insight into future possibilities for the recovery of a desired resource. The resource numbers themselves only useful when related to economically controlled factors, such as industry capability as reflected in rated of production, rates of discovery, and technology development. To that end, it is useful to divide the resource base into component parts to which appropriate econometrics can be applied. A system of resource reporting adhering to these principles has been agreed to by the two major resource agencies in Government, the U>S. Geological Survey and the U.S. Bureau of Mines (USGS Bulletin 1450-A). Conceptually, then, a plan for resource reporting has been devised, and all resource reporting by these two agencies follows the agreed-upon pattern. Though conceptual agreement has been reached, each commodity has its own peculiar data problems; hence an operational definition to fit the conceptual pattern must be evolved for each mineral. Coal is the only commodity to date for which an operational agreement has been reached (USGS Bulletin 1450-B), but the basic essentials of an operational classification within the guideline of Bulletin 1450-A have been reported for oil and gas in USGS circular 725. The basic classification system is now well established and received general endorsement by Resources for the Future in a study of mineral resource classification systems prepared for the the Electric Power Research Institute (Schanz, 1976), and with respect to coal by the International Energy Agency.

Technology advancement: a factor in increasing resource use

Wilburn, David R.; Goonan, Thomas G.; Bleiwas, Donald I.

2001-01-01

The specter of mineral resource scarcity has been repeatedly raised as a concern because ever-growing populations with seemingly insatiable appetites for minerals place claims against a finite resource endowment. This report analyzes how technology has helped to ease resource constraints, and uses case studies of aluminum, copper, potash, and sulfur minerals to identify the effects of technology on resource supply. In spite of heightened demand for and increased loss of resources to environmental policy and urbanization, mineral producers historically have been able to continually expand production and lower costs. Specific production increases for the years 1900-98 were: aluminum (3,250 percent), copper (2,465 percent), potash (3,770 percent), and sulfur (6,000 percent). For the same period, constant-dollar (1998) prices decreased: aluminum (90 percent), copper (75 percent), potash (94 percent), and sulfur (89 percent). The application of technology has made available mineral deposits that were previously overlooked or considered non-viable. Using technology, producers can meet the demand for stronger, energy-efficient, more environmentally safe products with less physical material. Technologies have been developed to increase the amount of materials recycled and remanufactured. Technology development can occur in breakthroughs, but most often advances incrementally. Technological development is driven by the profit motive.

Raw material monitoring assists companies. German Mineral Resources Agency at BGR provides information on global developments in resource markets

2016-01-01

Germany is dependent on imports for its metalliferous natural resources. Although prices have been declining significantly in recent months, numerous raw materials such as platinum, cobalt and rare earth elements continue to be exposed to price and supply risks. To ensure that German industry can respond better to this situation in their procurement activities, the German Mineral Resources Agency (DERA) at BGR has developed a raw material monitoring system on behalf of the German government. DERA experts have con figured a screening method for the early identification of possible procurement risks. This is the platform which enables German companies to gain the specific advice they require. All of the most important information on this issue is bundled within DERA 's internet portal (www.deutsche-rohstoffagentur.de). BGR also provides its expertise in other important fields with great societal relevance. BGR has been advising the national commission on ''Storage of High-level Radioactive Waste'' since 2014. Due to their comprehensive research activities in the field of radioactive waste disposal, BGR scientists are important technical experts to which the commission can turn to for geological information and advice.

Federal reservation of geothermal resources

Energy Technology Data Exchange (ETDEWEB)

Silver, R.M.

1978-01-01

Union Oil had developed or was seeking to develop wells on the land in Sonoma County, California in order to produce geothermal steam for generating electricity. The US Attorney General brought a quiet title action pursuant to 21(b) of the Geothermal Steam Act of 1970 to determine whether geothermal resources are included in the mineral reservation under the Homestead Act. The US District Court granted Union Oil's motion to dismiss for failure to state a claim upon which relief may be granted. On appeal, the Ninth Circuit reversed and remanded. In summary, the court concluded on the basis of the legislative history of the Stock-Raising Homestead Act that sources of energy are intended to remain in the government's possession, and the purposes of the Act will be best served by including geothermal resources in the reservation of mineral interests. Noting the strictly agricultural purpose of the Act, the subsurface estate reservation was broadly interpreted, even though title passed to all rights that were not expressly reserved. The court left open on remand the question of estoppel of the government from interfering with private lessees by developing subsurface resources compensation.This is a unique and intriguing decision, as it opens wide the definition of ''mineral interest,'' construing it in the timely terms of a valuable natural resource that may be in great demand for future energy needs. The decision is being appealed to the United States Supreme Court, and it will be interesting to observe whether this liberal interpretation of mineral interests will be upheld.

Geology and industrial mineral resources of the Macon-Gordon Kaolin District, Georgia

The Macon-Gordon kaolin district is about 80 miles (130 km) southeast of Atlanta, Georgia. It extends across the boundary between, and includes parts of, the Piedmont and Atlantic Coastal Plain physiographic provinces. The rocks in the Piedmont are mainly intensely folded sericite schist and granite gneiss containing irregular masses of amphibolite and feldspathic biotite gneiss and scattered igneous intrusive rocks. Most of the crystalline rocks are thought to be of Paleozoic age, but some of the intrusive rocks may be younger. The crystalline rocks are cut by a major unconformity and are overlain by sedimentary formations ranging in age from Cretaceous to Miocene. The valuable kaolin deposits occur in the Cretaceous beds, undivided, and in the Huber Formation which is of Paleocene to middle Eocene age. The resources of kaolin in the district are estimated in millions of metric tons as follows: reserves, 100; subeconomic resources, 700 to 900; undiscovered resources, probably 700 to 1,000. In addition to kaolin, the leading mineral commodity mined in the district, crushed stone and sand are now being produced, and fuller's earth and a minor amount of limestone were formerly produced. The crushed stone is quarried from igneous rocks in the Piedmont province. The sand is washed from the Cretaceous beds, undivided. The fuller's earth was mined from the Twiggs Clay Member of the Barnwell Formation, and limestone was dug from the Tivola Limestone.

The Australian mineral resources industry in 2006 - ongoing business and new challenges

Australia has the potential to remain as a stable long-term supplier of important minerals for the entire world (Table 1). The national income of Australia is direct related to the exports of minerals and it is no wonder that the annual poker-style price negotiations for iron ore and coking coal have become the most important events on the Australian economic calendar. The 2005 price increases for the two biggest export commodities, iron ore and coal, alone have contributed to a 2% rise of the national income. The total value of exported minerals will be 91.8 bn AS in 2006/2007. This boom was mainly driven by the surge of demand from China. In addition to iron ore and coal there are also gold, copper, nickel, bauxite, and many more metals which are creating headlines. Diamond and recently uranium mining have become hot topics. Besides the big players there are hundreds of small exploration and mining companies especially in the gold and base metal sector. Australia's rich resources, social stability and economic strengths have shaped a unique investment environment which continues to attract investors from around the world. The following will give you an overview on Australia's supply potential for the most important minerals. (orig.)

Alaska has considerable potential for undiscovered mineral resources. This report evaluates potential for undiscovered critical minerals in Alaska. Critical minerals are those for which the United States imports more than half of its total supply and which are largely derived from nations that cannot be considered reliable trading partners. In this report, estimated resource potential and certainty for the state of Alaska are analyzed and mapped for the following six selected mineral deposit groups that may contain one or more critical minerals: (1) rare earth elements-thorium-yttrium-niobium(-uranium-zirconium) [REE-Th-Y-Nb(-U-Zr)] deposits associated with peralkaline to carbonatitic igneous intrusive rocks; (2) placer and paleoplacer gold (Au) deposits that in some places might also produce platinum group elements (PGE), chromium (Cr), tin (Sn), tungsten (W), silver (Ag), or titanium (Ti); (3) platinum group elements(-cobalt-chromium-nickel-titanium-vanadium) [PGE(-Co-Cr-Ni-Ti-V)] deposits associated with mafic to ultramafic intrusive rocks; (4) carbonate-hosted copper(-cobalt-silver-germanium-gallium) [Cu(-Co-Ag-Ge-Ga)] deposits; (5) sandstone-hosted uranium(-vanadium-copper) [U(-V-Cu)] deposits; and (6) tin-tungsten-molybdenum(-tantalum-indium-fluorspar) [Sn-W-Mo(-Ta-In-fluorspar)] deposits associated with specialized granites.This study used a data-driven, geographic information system (GIS)-implemented method to identify areas that have mineral resource potential in Alaska. This method systematically and simultaneously analyzes geoscience data from multiple geospatially referenced datasets and uses individual subwatersheds (12-digit hydrologic units) as the spatial unit of classification. The final map output uses a red, yellow, green, and gray color scheme to portray estimated relative potential (High, Medium, Low, Unknown) for each of the six groups of mineral deposit types, and it indicates the relative certainty (High, Medium, Low) of that estimate for

Arctic resources : a mechatronics opportunity

This paper discussed the telerobotic mechatronics opportunities that exist to access mineral resources in the Arctic. The Mining Automation Project (MAP) determined that telerobotics could contribute to productivity gains while providing increased worker safety. The socio-economic benefits of advanced mechatronics for Arctic resource development are particularly attractive due to reduced infrastructure needs; operating costs; and environmental impacts. A preliminary analysis of mining transportation options by the authors revealed that there is a case for in-situ resource utilization (ISRU) for oil and gas processing to address resource development. The ISRU options build on concepts developed to support space exploration and were proposed to reduce or modify transportation loads to allow more sustainable and efficient Arctic resource development. Many benefits in terms of efficiency could be achieved by combining demonstrated mechatronics with ISRU because of the constrained transportation infrastructure in the Arctic. In the context of harsh environment operations, mechatronics may provide an opportunity for undersea resource facilities. 15 refs., 6 figs.

Both steelmaking via an electric arc furnace and manufacturing of portland cement are energy-intensive and resource-exploiting processes, with great amounts of carbon dioxide (CO 2 ) emission and alkaline solid waste generation. In fact, most CO 2 capture and storage technologies are currently too expensive to be widely applied in industries. Moreover, proper stabilization prior to utilization of electric arc furnace slag are still challenging due to its high alkalinity, heavy metal leaching potentials and volume instability. Here we deploy an integrated approach to mineralizing flue gas CO 2 using electric arc furnace slag while utilizing the reacted product as supplementary cementitious materials to establish a waste-to-resource supply chain toward a circular economy. We found that the flue gas CO 2 was rapidly mineralized into calcite precipitates using electric arc furnace slag. The carbonated slag can be successfully utilized as green construction materials in blended cement mortar. By this modulus, the global CO 2 reduction potential using iron and steel slags was estimated to be ~138 million tons per year.

Full Text Available Natural resources are a common good and the common wealth of each country. Their use, commercial applications and economic evaluation should be planned focused and targeted controlled. In a group of natural resources include: energy resources, water, food, land, mineral resources, biological resources and others. Given that the conditions of resource exploitation variable categories, it can be said that the volume of resources also variable. Abstracting growing problem of resources scarcity of vital importance to the existence in the world, this paper aims to try to shed light on the wider and comprehensive aspects of contemporary global problems in the scarcity of natural resources with a focus on the deficit of food, water and energenata. Search for answers to questions related to the scarcity of the basic needs of some of the world's population, civilizational confrontation about the energy pie, is a research and empirical contribution to the work, which is reflected in the effort to look at global challenges that mankind faces in the second decade of the 21st century.

Principles of classification of NIS reserves ampersand resources

1993-01-01

The newly independent states of the former Soviet Union (NIS) control large resources of uranium. These resources have been the subject of substantial debate within several forums of the Western uranium industry because of confusion surrounding the degree of correlation between the Soviet and various Western classification systems. As illustrated in this article, although developed independently of Western systems, the classification system used by the NIS is very definitive and provides a sound basis for resource reporting. In 1981 a new open-quotes System of Classification of Reserves and Resources of Mineral Depositsclose quotes was adopted. This classification system, which is still used today in the newly independent states of the former Soviet Union (NIS), subdivides mineral deposits into seven categories in three major groups, based on the level of exploration performed: (1) Explored Reserves (A, B, C 1 ); (2) Evaluated Reserves (C 2 ); and (3) Predicted Resources (P 1 , P 2 , P 3 )

Alberta Chamber of Resources : 1997 resources guide and directory

1997-01-01

The Alberta Chamber of Resources (ACR) is composed of 140 member companies from the oil and gas industry, forestry, pulp and paper, mining, oil sands, utilities, contractors, suppliers, consultants, banking and other service groups, as well as representatives from universities and governments. ACR's activities during 1996 were reviewed. These included supporting or sponsoring a careers forum, and various other networking and information sharing opportunities, a study of the potential for Alberta's minerals industry, and exploring opportunities for research in the forestry sector and the further development of Alberta's oil sands. Studies of the transportation and infrastructures strategies for Alberta's resources, royalty regimes, tenure and compensation issues associated with oil sands reservoirs that are 'capped' by natural gas reservoirs, taxation issues related to oil sands development, mineral rights tenure, and toll design and royalty issues affecting Alberta's natural gas sector rounded out the Chamber's activities. The annual review also profiled a number of ACR member companies, among them Koch Oil Company Ltd., Pardee Equipment Ltd., Interprovincial Pipe Line Inc., Clearwater Welding and Fabricating Ltd., and Weldwood of Canada.

geographic, economic, preemptive use, environmental, geologic and political factors. In addition, offshore sand resources should only be considered if the area is seaward of the active zone of significant nearshore sediment transport, about 10 to 12 m in depth, and in sufficiently shallow water so that sand can be extracted within U.S. dredging equipment limits, currently about 40 m in depth. If the material is to be used for beach nourishment, material must be of an appropriate sediment texture and character (grain size, sorting, shape, and color) to match the native beach and have mineralogical properties important to its use. Extraction of sand can disturb or alter the benthic habitat and seafloor ecology, so these factors and other site-specific effects will need to be evaluated for any intended use. These and other factors are not considered in this report but can be expected to reduce the total net volume of sand resources available for production. The purpose of this report is to describe and present results from a probabilistic mineral modeling technique previously applied to onshore mineral resources. This modeling and assessment procedure is being used for the first time to assess and estimate offshore aggregate resources; this study is part of the U.S. Geological Survey (USGS) Marine Aggregates Resources and Processes Project (http://woodshole.er.usgs.gov/project-pages/aggregates/).

Investigating the effectiveness of different forms of mineral resources governance in meeting the objectives of the UK petroleum fiscal regime

International Nuclear Information System (INIS)

Abdo, Hafez

2014-01-01

After 40 years of oil investments, the UK is now a mature oil province. During these 40 years or so, the UK Government has changed the type of governance it uses to manage its petroleum resources. This paper introduces the theoretical background to two models of mineral resource governance: proprietorial and non-proprietorial regimes. It investigates how adoption any of these two models by the UK Government has historically affected the achievement of the objectives of the UK petroleum fiscal regime. The analysis tracks the changes in the governance of the UK petroleum resources using changes in the average petroleum tax rate, and how this last influenced the achievement of the objectives of the UK petroleum Regime. The findings remain significant for their policy implications. The study concludes that the UK Government adopted a proprietorial type of mineral governance during the period 1975–1982, before changing to a non-proprietorial regime in the period 1983–2000. Since 2000 it has begun to move back towards a proprietorial style of governance. The excessive use of one type of these modes of governance leads to the objectives of the UK petroleum fiscal regime being not met. - Highlights: • UK petroleum fiscal regime has historically been unstable, It has shifted between two different types of minerals governance. • Proprietorial and non-proprietorial philosophies of minerals governance have been used exchangeable in the UK. • Excessive use of either type of governance restricts meeting objectives of the UK petroleum fiscal regime. • The UK needs to use a transparent type of minerals governance by using tools from the two governance philosophies

Resourcing Future Generations - Challenges for geoscience: a new IUGS initiative

Science.gov (United States)

Oberhänsli, Roland; Lambert, Ian

2014-05-01

In a world with rapidly increasing population and technological development new space based remote sensing tools allowed for new discoveries and production of water, energy- and mineral-resources, including minerals, soils and construction materials. This has impact on politics, socio-economic development and thus calls for a strong involvement of geosciences because one of humanities biggest challenges will be, to rise living standards particularly in less developed countries. Any growth will lead to an increase of demand for natural resources. But especially for readily available mineral resources supply appears to be limited. Particularly demand for so called high-tech commodities - platinum group or rare earth elements - increased. This happened often faster than new discoveries were made. All this, while areas available for exploration decreased as the need for urban and agricultural use increased. Despite strong efforts in increasing efficiency of recycling, shortage in some commodities has to be expected. A major concern is that resources are not distributed evenly on our planet. Thus supplies depend on political stability, socio-economic standards and pricing. In the light of these statements IUGS is scoping a new initiative, Resourcing Future Generations (RFG), which is predicated on the fact that mining will continue to be an essential activity to meet the needs of future generations. RFG is aimed at identifying and addressing key challenges involved in securing natural resources to meet global needs post-2030. We consider that mineral resources should be the initial focus, but energy, soils, water resources and land use should also be covered. Addressing the multi-generational needs for mineral and other natural resources requires data, research and actions under four general themes: 1. Comprehensive evaluation and quantification of 21st century supply and demand. 2. Enhanced understanding of subsurface as it relates to mineral (energy and groundwater

China, the United States, and competition for resources that enable emerging technologies

Science.gov (United States)

Gulley, Andrew L.; Nassar, Nedal T.; Xun, Sean

2018-01-01

Historically, resource conflicts have often centered on fuel minerals (particularly oil). Future resource conflicts may, however, focus more on competition for nonfuel minerals that enable emerging technologies. Whether it is rhenium in jet engines, indium in flat panel displays, or gallium in smart phones, obscure elements empower smarter, smaller, and faster technologies, and nations seek stable supplies of these and other nonfuel minerals for their industries. No nation has all of the resources it needs domestically. International trade may lead to international competition for these resources if supplies are deemed at risk or insufficient to satisfy growing demand, especially for minerals used in technologies important to economic development and national security. Here, we compare the net import reliance of China and the United States to inform mineral resource competition and foreign supply risk. Our analysis indicates that China relies on imports for over half of its consumption for 19 of 42 nonfuel minerals, compared with 24 for the United States—11 of which are common to both. It is for these 11 nonfuel minerals that competition between the United States and China may become the most contentious, especially for those with highly concentrated production that prove irreplaceable in pivotal emerging technologies.

The effect of resource quantity and resource stoichiometry on microbial carbon-use-efficiency

The carbon-use-efficiency (CUE) of microorganisms is an important parameter in determining ecosystem-level carbon (C) cycling; however, little is known about how variance in resources affects microbial CUE. To elucidate how resource quantity and resource stoichiometry affect microbial CUE, we cultured four microorganisms - two fungi (Aspergillus nidulans and Trichoderma harzianum) and two bacteria (Pectobacterium carotovorum and Verrucomicrobium spinosum) - under 12 unique C, nitrogen (N) and phosphorus (P) ratios. Whereas the CUE of A. nidulans was strongly affected by C, bacterial CUE was more strongly affected by mineral nutrients (N and P). Specifically, CUE in P. carotovorum was positively correlated with P, while CUE of V. spinosum primarily depended on N. This resulted in a positive relationship between fungal CUE and resource C : nutrient stoichiometry and a negative relationship between bacterial CUE and resource C : nutrient stoichiometry. The difference in the direction of the relationship between CUE and C : nutrient for fungi vs. bacteria was consistent with differences in biomass stoichiometry and suggested that fungi have a higher C demand than bacteria. These results suggest that the links between biomass stoichiometry, resource demand and CUE may provide a mechanism for commonly observed temporal and spatial patterns in microbial community structure and function in natural habitats.

Resource curse: An analysis of causes, experiences and possible ways forward

International Nuclear Information System (INIS)

Stevens, Paul; Dietsche, Evelyn

2008-01-01

Higher prices for oil, gas and mineral resources have again raised questions about how exporting countries can counter the challenges of resource curse. International experience managing the risks of resource curse has varied. Summarising the continuing discussion on meeting the challenges of the resource curse, this paper addresses four questions: What are the positive and negative effects of high oil, gas and mineral prices on exporters? What have been the experiences with managing natural resource revenues? Can good institutions ensure that natural resource revenues have a positive impact on development? And what is the direction for the way forward? We argue that the current emphasis on 'institutions' as a potential solution has largely ignored under what conditions institutions are formed and changed. (author)

The main report of the Task Force (NP-22249) is accompanied by four major research studies, published as Appendices to the main report, and covering the broad subjects of the taxation of non-renewable resources, a survey of our oil and gas resources, a survey of our other mineral resources, and a possible plan for the development of our oil and gas reserves in the coming decade.

Canada's resources and the national interest

Energy Technology Data Exchange (ETDEWEB)

1977-01-01

This is the main report of the task force on the broad subjects of taxation of nonrenewable resources, a survey of oil and gas reserves, a survey of other mineral resources, and the development of an oil and gas energy plan for Canada. Individual reports on the subjects above were issued as separate appendices to this main report. The preliminary draft of the report was published in early 1976. The introductory chapter surveys the critical choices and their costs for Canada, followed by chapters on Canadian resources; availability of private resource capital investments and returns; the tax position of the nonrenewable resource industry; and Federal-provincial conflicts over resource revenue and jurisdiction. It is concluded that the future is likely to yield only possibly adequate returns after massive commitments of capital and the acceptance of large risks by all concerned; further, that a climate of cooperation between government and industry is needed.

2014-10-01

Full Text Available In this study presents the environmental aspects of the use, management and disposal of mineral wool. Fiber structure makes that wool products have many unique properties enabling them to be versatile. With all the advantages of mineral wool is one very significant drawback - does not decompose. From the point of view of slowing (retardation transformation of environmental resources, the introduction of mineral wool to crops under glass, in a very much reduced use of peatlands, which for reasons of natural resources are extremely important. On the other hand, problems of rational use of mineral wool already postconsumer caused among others formation of "wild dumps" and thus transforming the landscape, and, due to their characteristics (respirable fibers, the risk to health. Manufacture of asbestiform can cause ecological consequences within almost all elements of the environment. Therefore, the overall assessment of the impact in this case, mineral wool on the environment would need to be so. "Life cycle assessment" - called the method of LCA (Life Cycle Assessmentwhich is commonly called the "cradle to grave" - that is, from extraction of raw materials, through processing, exploitation, to the storage of waste. Therefore, the responsibility for the redevelopment of the post-production of mineral wool should lie with the producer of wool. These issues are the subject of discussion in this study.

2011-01-01

Unconventional uranium resources in China mainly include black-rock series, peat, salt lake and evaporitic rocks. Among them, uraniferous black-rock series, uraniferous phosphorite and uranium-polymetallic phosphorite connected with black-rock series are important types for the sustainable support of uranium resources in China. Down-faulting and epocontinental rift in continental margin are the most important and beneficial ore-forming environment for unconventional uranium resources of black-rock series in China and produced a series of geochemistry combinations, such as, U-Cd, U-V-Mo, U-V-Re, U-V-Ni-Mo and U-V-Ni-Mo-Re-Tl. Unconventional uranium resources of black-rock series in China is related to uranium-rich marine black-rock series which are made up of hydrothermal sedimentary siliceous rocks, siliceous phospheorite and carbonaceous-siliceous-pelitic rock and settled in the continental margin down-faulting and epicontinental rift accompanied by submarine backwash and marine volcano eruption. Hydrothermal sedimentation or exhalation sedimentary is the mechanism to form unconventional uranium resources in black-rock series or large scale uranium-polymetallic mineralization in China.

A Policy study on cooperation for the development of underground resources in North Korea

Energy Technology Data Exchange (ETDEWEB)

Hwang, Jung Nam [Korea Energy Economics Institute, Euiwang (Korea)

1999-03-01

For the smooth promotion of joint development program of underground resources in North Korea, it requires a domestic legal authority applicable when a private company begins the development program of underground resources in North Korea. It is recommended that the supply of initial fund of resources development program in North Korea will utilize the supply method of existing resources development subsidizing fund instead of establishing new fund. In the case of enlarging its program by minerals, it is desirable to support it by creating the South-North resources development cooperation fund for a certain period to attract voluntary participation of the private sector. In this study, minerals able to develop among natural minerals in North Korea were classified and presented by grouping according to the higher order. Also, a plan for institutionalizing this was sought by connecting a development program by types of minerals for the smooth operation of South-North resources development cooperation program. Considering types of minerals, area, and the size and cost of development, it should be operated step by step, but for programs realizable at once, it should be started in its early stage. It is recommended to review a step by step plan for mineral resources development in North Korea continuously in connection with other economic cooperation sector such as the manufacturing industry.

The Empresas Nucleares Brasileiras S.A. (NUCLEBRAS) has implemented and improved, since their foundation in 1974, several laboratories at the Centro de Desenvolvimento da Tecnologia Nuclear (CDTN), in Belo Horizonte (MG, Brazil), in order to develop capabilities in the analytical chemistry field. Skillful personnel, using a large spectrum of equipment and procedures, is already able to determine, fast and accurately, almost any chemical element in any matrix. About 340.000 analytical determinations have been performed during the last seven years, concerning mostly chemical elements of great importance in the mineral technology programs. This considerable amount of results has been used, specially, as a backup to assess Brazilian uranium resources. (Author) [pt

Sustainable Management of Mineral Resources-another view on criticality.

Science.gov (United States)

Wellmer, F.-W.

2012-04-01

Generally investigations of criticality capture the supply risks on one hand and on the other hand the impact on the economy, the vulnerability to supply disruptions. The classification is a relative one and the analyses are always only a snapshot of a dynamic system: in the seventies of the last century chromium was generally considered the most critical metal. Today others are considered far more critical. These are especially the rare earth and the platinum group elements. Regardless in which direction technology develops these elements together with the steel alloy and electronic metal elements will most probably be the decisive elements to produce the high-tech products necessary for the well-being of Europe in the 21st century. These elements- often in small quantities- have a high economic lever effect. In a new research programme of the German Ministry of Education and Research they have been termed, therefore: economic-strategic raw materials. This paper will concentrate not so much on the critical materials as such, but on the factors critical in the background, critical to produce them: water, energy and the social acceptance of mining —the license to operate. From the point of sustainable management of mineral resources an important question with regard to critical aspects is also, how fast and to what extent mankind is able to reactivate the secondary materials in the technosphere to replace resource requirements from the geosphere under the limiting factors to minimize the environmental impact and energy needs. There will always be losses which have to be compensated from the geosphere (thermodynamical impossibility of a 100% closed loop, losses due to different redox potential, losses due to dispersal effects like wear and corrosion), however losses occurring today due to low scrap values can be minimized by better technology. Developments are well under way to replace more and more relative proportions of the major metal needs by material from the

Marcela Bianchessi da Cunha-Santino

Full Text Available Abstract: Aim The aim of this study was to quantify the emission rates of gases resulting from the anaerobic decomposition of different plant resources under conditions usually found in sediments of tropical aquatic systems and drained organic soils. Methods Incubations were prepared with green leaves, bark, twigs, plant litter, sugarcane stalks and leaves, soybean leaves, grasses, forest leaves and an aquatic macrophyte (Typha domingensis. Over 10 months, the daily volume of gas evolved from decay was measured and a kinetic model was used to describe the anaerobic mineralization. Results Using the mathematical model, it can be observed that the composition of the plant resources is heterogeneous. The temporal variation of the gas rates indicated that the mineralization of the labile fractions of detritus varied, on a carbon basis, from 16.2 (bark to 100% (samples composed of leaves, grasses and sugar cane stalks. High gas emissions were observed during the mineralization of grasses, sugar cane stalks, leaves and plant litter, while low volumes of gases were measured during the mineralization of bark, twigs, forest leaves and T. domingensis, which are the most fibrous and recalcitrant resources (carbon content: 83.8, 78.2, 64.8 and 53.4%, respectively. The mineralization of labile carbon presented half-life values, which varied from 41 (twigs to 295 days (grasses. Conclusions Considering the high amount of remaining recalcitrant fraction, the anaerobic decomposition of these plant resources showed a strong trend towards accumulating organic matter in flooded soils. Despite the higher temperatures found in the tropical environment, these environments represent a sink of particulate detritus due to its slow decomposition.

Moon Prospective Energy and Material Resources

CERN Document Server

2012-01-01

The Earth has limited material and energy resources. Further development of the humanity will require going beyond our planet for mining and use of extraterrestrial mineral resources and search of power sources. The exploitation of the natural resources of the Moon is a first natural step on this direction. Lunar materials may contribute to the betterment of conditions of people on Earth but they also may be used to establish permanent settlements on the Moon. This will allow developing new technologies, systems and flight operation techniques to continue space exploration.   In fact, a new branch of human civilization could be established permanently on Moon in the next century. But, meantime, an inventory and proper social assessment of Moon’s prospective energy and material resources is required. This book investigates the possibilities and limitations of various systems supplying manned bases on Moon with energy and other vital resources.

Shroder, J. F.

2002-05-01

Mineral and water resources in Afghanistan may be the best means by which redevelopment of the country can be used to alleviate future terrorism. Remote-sensing analysis of snow, ice, resources, and topography in Afghanistan, and development of digital elevation models with ASTER imagery and previously classified, large scale topographic maps from the Department of Defense enable better assessment and forecasting resources in the country. Adequate resource assessment and planning is viewed as critical to alleviation of one cause of the problems associated with the fertilization of terrorism in Afghanistan. Long-term diminution of meltwater resources in Afghanistan is exemplified by the disastrous and famine-inducing droughts of the present time and three decades prior, as well as by the early Landsat assessment of glacier resources sponsored by USGS and now brought up-to-date with current imagery. Extensive cold-war projects undertaken by both the USSR and USA generated plentiful essential mineral, hydrocarbon, hydrogeological, and hydrological data, including an extensive stream gauging and vital irrigation network now adversly affected or destroyed entirely by decades of war. Analysis, measurement, prediction, rehabilitation, and reconstruction of critical resource projects are regarded as most critical elements in the war on terrorism in this portion of the world. The GLIMS (Global Land Ice Measurements from Space) Project, initially sponsored by USGS, has established our group as the Regional Center for Afghanistan and Pakistan, in which the above concepts serve as guiding research precepts.

Full Text Available One of the priorities of Russia's transition to post-industrial development is the upgrade of mineral resources sector as a major system-building industry which includes exploration, extraction, refining, transportation and processing of minerals. The main directions of modernization in the subsoil resources management are improvement of methods and technologies under exploration, automation and computerization of work and equipment at the stages of production and transportation of mineral resources, improvement of equipment and technology with the use of nanotechnology in the stages of enrichment and processing of mineral raw materials. Actual direction of modernization in the ore mining industry today is creation and improvement of techniques and technologies to work in the northern climate according to the Program of subsoil resources development of the North and the Arctic shelf. Due to the exhaustion of large raw mineral deposits and geological complexity of the conditions of mining, there is a need for new types of mining and extraction equipment in the industry and development of processes to extract minerals from the non-traditional raw materials.

Space and Planetary Resources

The space and multitude of celestial bodies surrounding Earth hold a vast wealth of resources for a variety of space and terrestrial applications. The unlimited solar energy, vacuum, and low gravity in space, as well as the minerals, metals, water, atmospheric gases, and volatile elements on the Moon, asteroids, comets, and the inner and outer planets of the Solar System and their moons, constitute potential valuable resources for robotic and human space missions and for future use in our own planet. In the short term, these resources could be transformed into useful materials at the site where they are found to extend mission duration and to reduce the costly dependence from materials sent from Earth. Making propellants and human consumables from local resources can significantly reduce mission mass and cost, enabling longer stays and fueling transportation systems for use within and beyond the planetary surface. Use of finely grained soils and rocks can serve for habitat construction, radiation protection, solar cell fabrication, and food growth. The same material could also be used to develop repair and replacement capabilities using advanced manufacturing technologies. Following similar mining practices utilized for centuries on Earth, identifying, extracting, and utilizing extraterrestrial resources will enable further space exploration, while increasing commercial activities beyond our planet. In the long term, planetary resources and solar energy could also be brought to Earth if obtaining these resources locally prove to be no longer economically or environmentally acceptable. Throughout human history, resources have been the driving force for the exploration and settling of our planet. Similarly, extraterrestrial resources will make space the next destination in the quest for further exploration and expansion of our species. However, just like on Earth, not all challenges are scientific and technological. As private companies start working toward

Resource impact: curse or blessing? a literature survey

International Nuclear Information System (INIS)

Stevens, P.

2003-01-01

Common sense and economic theory suggest large revenues from natural resource projects should generate economic progress and development. Yet much evidence argues the opposite and that resource-rich countries suffer from 'resource curse'. This paper provides a survey of the academic literature on the impact of natural resources on an economy. The topic has long attracted interest in the economics literature but more recently, interest has revived. The paper first considers the large body of empirical work examining the relationship between resource abundance, poor economic performance and poverty. While this evidence supports the view of a negative impact, it is not without criticism and some assert a few countries managed instead to receive a 'blessing'. The paper assesses how the literature explains the transmission mechanisms between resource revenues and economic damage. Six areas are discussed: a long-term decline in terms of trade; revenue volatility; Dutch disease; crowding out effects; increasing the role of the state; and the sociocultural and political impacts. Finally, various options from the literature to avoid negative impacts are analysed: not developing the mineral deposits; diversifying the economy away from dependence on oil, gas and mineral exports; sterilising the incoming revenue; the use of stabilisation and oil funds; and reconsidering investment policies. The paper finishes by assessing what political reforms might be needed to carry out the necessary policies to avoid negative impacts. (author)

International standardisation for the reporting of resources and reserves

International Nuclear Information System (INIS)

Farmer, K.

2014-01-01

The mining industry is a vital contributor to national and global economies and yet it is very different from other industries. It is based on depleting finite mineral resources, the knowledge of which is imperfect prior to the commencement of mining or extraction. It is an industry with a colourful history of success and failure, entrepreneurs and opportunists, visionaries and short sightedness. These aspect or traits were both positive, it fostered innovation, and negative for the industry. Negative in that the merit of certain projects or results was difficult to assess, it created a credibility issue and consequently investment in the industry was impacted. In 1989 the first JORC code was released (Joint Ore Reserves Committee) in Australia. It was incorporated into the Australian Stock Exchange (ASX) listing rules thereby becoming binding on companies listed on the ASX it was also adopted by the Australian Institute of Mining and Metallurgy (AusIMM) and became binding on its members. Essentially JORC was the pre-cursor or model for an international standard for the reporting of exploration results, mineral resources and ore reserves. A trend towards tighter corporate governance and regulation demanded an international standard to “good practice” in mineral reserve management as well as high standards of public reporting by responsible, experienced persons. In 2006 CRIRSCO (Committee for Mineral Reserves International Reporting Standards)released an International Reporting Template (the Template), the purpose of which is to assist with the dissemination and promotion of effective, well-tried, good practice for public reporting of Exploration Results, Mineral Resources and Ore Reserves already widely adopted through national reporting codes and standards. CRIRSCO’s members are National Reporting Organisations (NROs) that are responsible for developing mineral reporting codes, standards and guidelines in Australasia (JORC), Chile (National Committee

Mineral resource of the month: vermiculite

Science.gov (United States)

Tanner, Arnold O.

2014-01-01

Vermiculite comprises a group of hydrated, laminar magnesium-aluminum-iron silicate minerals resembling mica. They are secondary minerals, typically altered biotite, iron-rich phlogopite or other micas or clay-like minerals that are themselves sometimes alteration products of amphibole, chlorite, olivine and pyroxene. Vermiculite deposits are associated with volcanic ultramafic rocks rich in magnesium silicate minerals, and flakes of the mineral range in color from black to shades of brown and yellow. The crystal structure of vermiculite contains water molecules, a property that is critical to its processing for common uses.

From Dearth to El Dorado: Andean Nature, Plate Tectonics, and the Ontologies of Ecuadorian Resource Wealth

Directory of Open Access Journals (Sweden)

David Kneas

2018-03-01

Full Text Available Since the early 1990s, the Ecuadorian government has pledged to convert the nation into a “mining country” of global standing. Contemporary claims of mineral wealth, however, stand in stark contrast to previous assessments. Indeed, through much of the 20th century, geologists described Ecuador as a country of mineral dearth. Exploring the process through which Ecuador seemingly transitioned from a nation of resource scarcity to one of mineral plenty, I demonstrate how assessments of Ecuador’s resource potential relate to ideas of Andean nature. Promoters of resource abundance have emphasized Andean uniformity and equivalence—the notion that Ecuador’s mineral wealth is inevitable by virtue of the resource richness of its Andean neighbors. Geologists who have questioned Ecuador’s mineral content, on the other hand, have emphasized Andean heterogeneity. In the recent promotion of Ecuador’s resource potential, notions of Andean uniformity have been bolstered by models of subsoil copper that emerged in the in 1970s in the context of plate-tectonic theory. In highlighting the linkage between ideas of Andean nature and appraisals of Ecuadorian resource potential since the late 19th century, I outline the dialectics between nature and natural resources that underpin processes of resource becoming.

Geological structure and mineral resources of Algeria

Eduard Dobra

2007-12-01

Full Text Available The hydrocarbon System Ourd Mya is located in the Sahara Basin. It is one of the producing basins in Algeria. The stratigraphic section consists of Paleozoic and Mesosoic, it is about 5000 m thick. In the eastern part, the basin is limited by the Hassi-Messaoud high zone which is a giant oil field produced from the Cambrian sands. The western part is limited by Hassi R`mel which is one of the biggest gas field in the world, it is produced from the triassic sands. The Mesozoic section lays on the lower Devonian and in the eastern part, on the Cambrian. The main source rock is Silurian shale with an average thickness of 50 m and a total organic matter of 6 % (14 % in some cases. Results of maturation modeling indicate that the lower Silurian source is in the oil window. The Ordovician shales are also a source rock but in a second order. Clastic reservoirs are in the Triassic sequence which is mainly fluvial deposit with complex alluvial channels, it is the main target in the basin. Clastic reservoirs within the lower Devonian section have a good hydrocarbon potential in the east of the basin through a southwest-northeast orientation. The late Triassic-Early Jurassic evaporites overlie the Triassic clastic interval and extend over the entire Oued Mya Basin. This is considered as a super-seal evaporate package, which consists predominantly of anhydrite and halite. For Paleozoic targets, a large number of potential seals exist within the stratigraphic column.This paper describe the main geological structure and mineral resources of Algeria.

Hall, R.B.; Feininger, Tomas; Barrero, L.; Dario, Rico H.; ,; Alvarez, A.

1970-01-01

The mineral resources of an area of 40,000 sq km, principally in the Department of Antioquia, but including small parts of the Departments of Caldas, C6rdoba, Risaralda, and Tolima, were investigated during the period 1964-68. The area is designated Zone II by the Colombian Inventario Minero Nacional(lMN). The geology of approximately 45 percent of this area, or 18,000 sq km, has been mapped by IMN. Zone II has been a gold producer for centuries, and still produces 75 percent of Colombia's gold. Silver is recovered as a byproduct. Ferruginous laterites have been investigated as potential sources of iron ore but are not commercially exploitable. Nickeliferous laterite on serpentinite near Ure in the extreme northwest corner of the Zone is potentially exploitable, although less promising than similar laterites at Cerro Matoso, north of the Zone boundary. Known deposits of mercury, chromium, manganese, and copper are small and have limited economic potentia1. Cement raw materials are important among nonmetallic resources, and four companies are engaged in the manufacture of portland cement. The eastern half of Zone II contains large carbonate rock reserves, but poor accessibility is a handicap to greater development at present. Dolomite near Amalfi is quarried for the glass-making and other industries. Clay saprolite is abundant and widely used in making brick and tiles in backyard kilns. Kaolin of good quality near La Union is used by the ceramic industry. Subbituminous coal beds of Tertiary are an important resource in the western part of the zone and have good potential for greater development. Aggregate materials for construction are varied and abundant. Deposits of sodic feldspar, talc, decorative stone, and silica are exploited on a small scale. Chrysotils asbestos deposits north of Campamento are being developed to supply fiber for Colombia's thriving asbestos-cement industry, which is presently dependent upon imported fiber. Wollastonite and andalusite are

1986-01-01

The extended abstracts in this volume are summaries of the papers presented orally and as posters in the second V. E. McKelvey Forum on Mineral and Energy Resources, entitled "USGS Research on Energy Resources-1986." The Forum has been established to improve communication between the USGS and the earth science community by presenting the results of current USGS research on nonrenewable resources in a timely fashion and by providing an opportunity for individuals from other organizations to meet informally with USGS scientists and managers. It is our hope that the McKelvey Forum will help to make USGS programs more responsive to the needs of the earth science community, particularly the mining and petroleum industries, and Win foster closer cooperation between organizations and individuals. The Forum was named after former Director Vincent E. McKelvey in recognition of his lifelong contributions to research, development, and administration in mineral and energy resources, as a scientist, as Chief Geologist, and as Director of the U.S. Geological Survey. The Forum will be an annual event, and its subject matter will alternate between mineral and energy resources. We expect that the format will change somewhat from year to year as various approaches are tried, but its primary purpose will remain the same: to encourage direct communication between USGS scientists and the representatives of other earth-science related organizations. Energy programs of the USGS include oil and gas, coal, geothermal, uranium-thorium, and oil shale; work in these programs spans the national domain, including surveys of the offshore Exclusive Economic Zone. The topics selected for presentation at this McKelvey Forum represent an overview of the scientific breadth of USGS research on energy resources. They include aspects of petroleum occurrence in Eastern United States rift basins, the origin of magnetic anomalies over oil fields, accreted terranes and energy-resource implications, coal

Lembah Hitam Sector is part of Schwaner Mountains and Kalan Basin upper part stratigraphy. Uranium (U) mineralization layer is associated with metasiltstone and metapelites schistose heading to N 265° E/60° S. Evaluation drilling carried out with a distance of 50 m from an existing point (FKL 14 and FKL 13) to determine the model and the amount of U resources in measured category. To achieve these objectives some activities including reviewing the previous studies, geological and U mineralization data collecting, grades quantitative estimation using log gross-count gamma ray, database and modeling creation and resource estimation of U carried out. Based on modeling on ten drilling data and completed with drilled core observation, the average grade of U mineralization in Lembah Hitam Sector obtained. The average grade is ranging from 0.0076 - 0.95 % eU_3O_8, with a thickness of mineralization ranging from 0.1 - 4.5 m. Uranium mineralization present as fracture filling (veins) or groups of veins and as matrix filling in tectonic breccia, associated with pyrite, pyrrhotite, magnetite, molybdenite, tourmaline and quartz in metasiltstone and metapelites schistose. Calculation of U resources to 26 ores body using 25 m searching radius resulted in 655.65 tons ores. By using 0.01 % cut-off grade resulted in 546.72 tons ores with an average grade 0.101 % eU_3O_8. Uranium resource categorized as low-grade measured resources. (author)

Exploration and extraction activities related to energy and mineral resources in the Borderlands—such as coal-fired power plants, offshore drilling, and mining—can create issues that have potentially major economic and environmental implications. Resource assessments and development projects, environmental studies, and other related evaluations help to understand some of these issues, such as power plant emissions and the erosion/denudation of abandoned mine lands. Information from predictive modeling, monitoring, and environmental assessments are necessary to understand the full effects of energy and mineral exploration, development, and utilization. The exploitation of these resources can negatively affect human health and the environment, its natural resources, and its ecological services (air, water, soil, recreation, wildlife, etc.). This chapter describes the major energy and mineral issues of the Borderlands and how geologic frameworks, integrated interdisciplinary (geobiologic) investigations, and other related studies can address the anticipated increases in demands on natural resources in the region.

3&4D Geomodeling Applied to Mineral Resources Exploration - A New Tool for Targeting Deposits.

2013-04-01

3 & 4D geomodeling, a computer method for reconstituting the past deformation history of geological formations, has been used in oil and gas exploration for more than a decade for reconstituting fluid migration. It begins nowadays to be applied for exploring with new eyes old mature mining fields and new prospects. We describe shortly the 3&4D geomodeling basic notions, concepts, and methodology when applied to mineral resources assessment and modeling ore deposits, pointing out the advantages, recommendations and limitations, together with new challenges they rise. Several 3D GeoModels of mining explorations selected across Europe will be presented as illustrative case studies which have been achieved during the EU FP7 ProMine research project. It includes: (i) the Cu-Au porphyry deposits in the Hellenic Belt (Greece); (ii) the VMS in the Iberian Pyrite Belt including the Neves Corvo deposit (Portugal) and (iii) the sediment-hosted polymetallic Cu-Ag (Au, PGE) Kupferschiefer ore deposit in the Foresudetic Belt (Poland). In each case full 3D models using surfaces and regular grid (Sgrid) were built from all dataset available from exploration and exploitation including geological primary maps, 2D seismic cross-sections, and boreholes. The level of knowledge may differ from one site to another however those 3D resulting models were used to pilot additional field and exploration works. In the case of the Kupferschiefer, a sequential restoration-decompaction (4D geomodeling) from the Upper Permian to Cenozoic was conducted in the Lubin- Sieroszowice district of Poland. The results help in better understanding the various superimposed mineralization events which occurred through time in this copper deposit. A hydro-fracturing index was then calculated from the estimated overpressures during a Late Cretaceous-Early Paleocene up-lifting, and seems to correlate with the copper content distribution in the ore-series. These results are in agreement with an Early Paleocene

Are natural resources bad for health?

Science.gov (United States)

El Anshasy, Amany A; Katsaiti, Marina-Selini

2015-03-01

The purpose of this paper is to empirically examine whether economic dependence on various natural resources is associated with lower investment in health, after controlling for countries' geographical and historical fixed effects, corruption, autocratic regimes, income levels, and initial health status. Employing panel data for 118 countries for the period 1990-2008, we find no compelling evidence in support of a negative effect of resources on healthcare spending and outcomes. On the contrary, higher dependence on agricultural exports is associated with higher healthcare spending, higher life expectancy, and lower diabetes rates. Similarly, healthcare spending increases with higher mineral intensity. Finally, more hydrocarbon resource rents are associated with less diabetes and obesity rates. There is however evidence that public health provision relative to the size of the economy declines with greater hydrocarbon resource-intensity; the magnitude of this effect is less severe in non-democratic countries.

1994-01-01

By applying the reliability theory in system engineering, the success tree method is used to transfer the expert's recognition on metallogenetic regularities into the form of the success tree. The aim of resources evaluation is achieved by means of calculating the metallogenetic probability or favorability of the top event of the success tree. This article introduces in detail, the source, principle of the success tree method and three kinds of calculation methods, expounds concretely how to establish the success tree of comprehensive uranium metallogenesis as well as the procedure from which the resources evaluation is performed. Because this method has not restrictions on the number of known deposits and calculated area, it is applicable to resources evaluation for different mineral species, types and scales and possesses good prospects of development

The Earth has limited material and energy resources. Further development of the humanity will require going beyond our planet for mining and use of extraterrestrial mineral resources and search of power sources. The exploitation of the natural resources of the Moon is a first natural step on this direction. Lunar materials may contribute to the betterment of conditions of people on Earth but they also may be used to establish permanent settlements on the Moon. This will allow developing new technologies, systems and flight operation techniques to continue space exploration. In fact, a new branch of human civilization could be established permanently on Moon in the next century. But, meantime, an inventory and proper social assessment of Moon's prospective energy and material resources is required. This book investigates the possibilities and limitations of various systems supplying manned bases on Moon with energy and other vital resources. The book collects together recent proposals and innovative options and solutions. It is a useful source of condensed information for specialists involved in current and impending Moon-related activities and a good starting point for young researchers. (orig.)

Through investigating and analyzing the present situation and the existing problems of resources and environment in Poyang Lake Eco-economic Zone, seven factors were chosen as the evaluation criterion layer, namely, land resources, water resources, biological resources, mineral resources, ecological-geological environment, water environment and atmospheric environment. Based on the single factor evaluation results and with the county as the evaluation unit, the comprehensive capacity of resources and environment was evaluated by using the state space method in Poyang Lake Eco-economic Zone. The results showed that it boasted abundant biological resources, quality atmosphere and water environment, and relatively stable geological environment, while restricted by land resource, water resource and mineral resource. Currently, although the comprehensive capacity of the resources and environments in Poyang Lake Eco-economic Zone was not overloaded as a whole, it has been the case in some counties/districts. State space model, with clear indication and high accuracy, could serve as another approach to evaluating comprehensive capacity of regional resources and environment.

The Budenovskoye deposit is the biggest sandstone-hosted, roll front type uranium deposit in Kazakhstan and in the world. Uranium mineralization occurs in the unconsolidated lacustrine-alluvial sediments of Late Cretaceous Mynkuduk and Inkuduk horizons. The Budenovskoye deposit was split into four areas for development with the present Karatau ISL Mine operating No. 2 area and Akbastau ISL Mine Nos. 1, 3 and 4 areas. Mines are owned by Kazatomprom and Uranium One in equal shares. CSA Global was retained by Uranium One to update in accordance with NI 43-101 the Mineral Resource estimates for the Karatau and Akbastau Mines. The modelling Reports shows a significant increase in total uranium resources tonnage at both mines when compared to the March 2012 NI 43-101 resource estimate: at Karartau measured and indicated resources increased by 586% while at Akbastau by 286%. It has also added a 55,766 tonnes U to the Karatau Inferred Mineral Resource category.The new estimates result from the application of 3-D modelling techniques to the extensive database of drilling information, new exploration activities.

Review of Biohydrometallurgical Metals Extraction from Polymetallic Mineral Resources

Directory of Open Access Journals (Sweden)

Helen R. Watling

2014-12-01

Full Text Available This review has as its underlying premise the need to become proficient in delivering a suite of element or metal products from polymetallic ores to avoid the predicted exhaustion of key metals in demand in technological societies. Many technologies, proven or still to be developed, will assist in meeting the demands of the next generation for trace and rare metals, potentially including the broader application of biohydrometallurgy for the extraction of multiple metals from low-grade and complex ores. Developed biotechnologies that could be applied are briefly reviewed and some of the difficulties to be overcome highlighted. Examples of the bioleaching of polymetallic mineral resources using different combinations of those technologies are described for polymetallic sulfide concentrates, low-grade sulfide and oxidised ores. Three areas for further research are: (i the development of sophisticated continuous vat bioreactors with additional controls; (ii in situ and in stope bioleaching and the need to solve problems associated with microbial activity in that scenario; and (iii the exploitation of sulfur-oxidising microorganisms that, under specific anaerobic leaching conditions, reduce and solubilise refractory iron(III or manganese(IV compounds containing multiple elements. Finally, with the successful applications of stirred tank bioleaching to a polymetallic tailings dump and heap bioleaching to a polymetallic black schist ore, there is no reason why those proven technologies should not be more widely applied.

Resource rent taxes and sustainable development: A Mongolian case study

International Nuclear Information System (INIS)

Thampapillai, Dodo J.; Hansen, Jan; Bolat, Aigerim

2014-01-01

Economies rich in mineral resources, need to evaluate the merits of investing rents earned from resource extraction in other income generating activities to sustain the flow of income. It is hence important to estimate and assess the potential uses of the resource rent tax (RRT). This paper illustrates how the reinvestment of the RRT and other government revenue from mining can reduce the depreciation of the mine. This illustration is made with reference to a coal deposit in the Tavan-Tolgoi region of Mongolia. The paper also illustrates impact of mining on the macroeconomic performance of Mongolia. Standard macroeconomic frameworks that ignore the depreciation of mineral assets overstate economic performance. The paper also reviews the political issues and constraints that surround the implementation of the RRT. One option canvassed here is the granting of qualified custodial rights of the RRT to the mining firm. Such qualified rights are pertinent given that the RRT is legally the income owed to the State and investments in ventures such as human capital development can yield returns as high as 10% per annum. This study illustrates that even an investment option yielding an annual 3% return can make a significant difference. - Highlights: • We estimate resource rents owed to the state from energy resource extraction. • We show that mining revenues are over-stated when the depreciation of mineral assets are ignored. • We show that the investment of resource rents offers avenues for sustaining the flow of income. • We argue that the state can grant custody of the rents to mining firms for the management of investments

The Organic Act of 1879 (43 USC 31) that established the US Geological Survey provided, among other things, for the classification of the public lands and for the examination of the geological structure, mineral resources, and products of the national domain. In order to provide uniform executive action in classifying public lands, standards for determining which lands are valuable for mineral resources, for example, leasable mineral lands, or for other products are prepared by the US Geological Survey. This report presents the classification standards for determining which Federal lands are classifiable as geothermal steam and associated geothermal resources lands under the Geothermal Steam Act of 1970 (84 Stat. 1566). The concept of a geothermal resouces province is established for classification of lands for the purpose of retention in Federal ownership of rights to geothermal resources upon disposal of Federal lands. A geothermal resources province is defined as an area in which higher than normal temperatures are likely to occur with depth and in which there is a resonable possiblity of finding reservoir rocks that will yield steam or heated fluids to wells. The determination of a known geothermal resources area is made after careful evaluation of the available geologic, geochemical, and geophysical data and any evidence derived from nearby discoveries, competitive interests, and other indicia. The initial classification required by the Geothermal Steam Act of 1970 is presented.

IntroductionThis circular provides an overview of selected activities that were conducted within the U.S. Geological Survey (USGS) Integrated Methods Development Project, an interdisciplinary project designed to develop new tools and conduct innovative research requiring integration of geologic, geophysical, geochemical, and remote-sensing expertise. The project was supported by the USGS Mineral Resources Program, and its products and acquired capabilities have broad applications to missions throughout the USGS and beyond.In addressing challenges associated with understanding the location, quantity, and quality of mineral resources, and in investigating the potential environmental consequences of resource development, a number of field and laboratory capabilities and interpretative methodologies evolved from the project that have applications to traditional resource studies as well as to studies related to ecosystem health, human health, disaster and hazard assessment, and planetary science. New or improved tools and research findings developed within the project have been applied to other projects and activities. Specifically, geophysical equipment and techniques have been applied to a variety of traditional and nontraditional mineral- and energy-resource studies, military applications, environmental investigations, and applied research activities that involve climate change, mapping techniques, and monitoring capabilities. Diverse applied geochemistry activities provide a process-level understanding of the mobility, chemical speciation, and bioavailability of elements, particularly metals and metalloids, in a variety of environmental settings. Imaging spectroscopy capabilities maintained and developed within the project have been applied to traditional resource studies as well as to studies related to ecosystem health, human health, disaster assessment, and planetary science.

Natural Resource Extraction, Armed Violence, and Environmental Degradation.

Downey, Liam; Bonds, Eric; Clark, Katherine

2010-12-01

The goal of this article is to demonstrate that environmental sociologists cannot fully explain the relationship between humans and the natural world without theorizing a link between natural resource extraction, armed violence, and environmental degradation. The authors begin by arguing that armed violence is one of several overlapping mechanisms that provide powerful actors with the means to (a) prevail over others in conflicts over natural resources and (b) ensure that natural resources critical to industrial production and state power continue to be extracted and sold in sufficient quantities to promote capital accumulation, state power, and ecological unequal exchange. The authors then identify 10 minerals that are critical to the functioning of the U.S. economy and/or military and demonstrate that the extraction of these minerals often involves the use of armed violence. They further demonstrate that armed violence is associated with the activities of the world's three largest mining companies, with African mines that receive World Bank funding, and with petroleum and rainforest timber extraction. The authors conclude that the natural resource base on which industrial societies stand is constructed in large part through the use and threatened use of armed violence. As a result, armed violence plays a critical role in fostering environmental degradation and ecological unequal exchange.

Rice Hulls as a Renewable Complex Material Resource

Directory of Open Access Journals (Sweden)

Irina Glushankova

2018-05-01

Full Text Available As a result of rice grain processing, a big amount of waste (up to 20% is produced. It is mainly rice hulls. The main components of rice hulls are cellulose, lignin and mineral ash. The mineral ash quantity in rice hulls varies from 15 up to 20%, by weight of the rice hulls. The mineral ash consists of amorphous silica (opal-type. Due to the high content of silica in rice hulls, the material burns with difficulty under natural conditions, and it is biodegradably destroyed only with difficulty, when composted. Utilization of rice hulls then becomes an ecological problem due to huge rice production and its continuous growth. At the same time, the annual quantity of silica content in rice hulls is comparable with the quantity of amorphous silica produced as a mineral resource. The issue of manufacturing cellular glass silica construction materials from rice hulls as a renewable resource is discussed in this paper. The utilization technology is based on an amorphous silicon oxide with the use of energy from the combustion of the organic component of rice hulls.

Systemic trade risk of critical resources.

Klimek, Peter; Obersteiner, Michael; Thurner, Stefan

2015-11-01

In the wake of the 2008 financial crisis, the role of strongly interconnected markets in causing systemic instability has been increasingly acknowledged. Trade networks of commodities are susceptible to cascades of supply shocks that increase systemic trade risks and pose a threat to geopolitical stability. We show that supply risk, scarcity, and price volatility of nonfuel mineral resources are intricately connected with the structure of the worldwide trade networks spanned by these resources. At the global level, we demonstrate that the scarcity of a resource is closely related to the susceptibility of the trade network with respect to cascading shocks. At the regional level, we find that, to some extent, region-specific price volatility and supply risk can be understood by centrality measures that capture systemic trade risk. The resources associated with the highest systemic trade risk indicators are often those that are produced as by-products of major metals. We identify significant strategic shortcomings in the management of systemic trade risk, in particular in the European Union.

Front Range Infrastructure Resources Project: water-resources activities

Robson, Stanley G.; Heiny, Janet S.

1998-01-01

Infrastructure, such as roads, buildings, airports, and dams, is built and maintained by use of large quantities of natural resources such as aggregate (sand and gravel), energy, and water. As urban area expand, local sources of these resource are becoming inaccessible (gravel cannot be mined from under a subdivision, for example), or the cost of recovery of the resource becomes prohibitive (oil and gas drilling in urban areas is costly), or the resources may become unfit for some use (pollution of ground water may preclude its use as a water supply). Governmental land-use decision and environmental mandates can further preclude development of natural resources. If infrastructure resources are to remain economically available. current resource information must be available for use in well-reasoned decisions bout future land use. Ground water is an infrastructure resource that is present in shallow aquifers and deeper bedrock aquifers that underlie much of the 2,450-square-mile demonstration area of the Colorado Front Range Infrastructure Resources Project. In 1996, mapping of the area's ground-water resources was undertaken as a U.S. Geological Survey project in cooperation with the Colorado Department of Natural Resources, Division of Water Resources, and the Colorado Water Conservation Board.

A Combined XRD/XRF Instrument for Lunar Resource Assessment

Robotic surface missions to the Moon should be capable of measuring mineral as well as chemical abundances in regolith samples. Although much is already known about the lunar regolith, our data are far from comprehensive. Most of the regolith samples returned to Earth for analysis had lost the upper surface, or it was intermixed with deeper regolith. This upper surface is the part of the regolith most recently exposed to the solar wind; as such it will be important to resource assessment. In addition, it may be far easier to mine and process the uppermost few centimeters of regolith over a broad area than to engage in deep excavation of a smaller area. The most direct means of analyzing the regolith surface will be by studies in situ. In addition, the analysis of the impact-origin regolith surfaces, the Fe-rich glasses of mare pyroclastic deposits, are of resource interest, but are inadequately known; none of the extensive surface-exposed pyroclastic deposits of the Moon have been systematically sampled, although we know something about such deposits from the Apollo 17 site. Because of the potential importance of pyroclastic deposits, methods to quantify glass as well as mineral abundances will be important to resource evaluation. Combined x ray diffraction (XRD) and x ray fluorescence (XRF) analysis will address many resource characterization problems on the Moon. XRF methods are valuable for obtaining full major-element abundances with high precision. Such data, collected in parallel with quantitative mineralogy, permit unambiguous determination of both mineral and chemical abundances where concentrations are high enough to be of resource grade. Collection of both XRD and XRF data from a single sample provides simultaneous chemical and mineralogic information. These data can be used to correlate quantitative chemistry and mineralogy as a set of simultaneous linear equations, the solution of which can lead to full characterization of the sample. The use of

Methods for the estimation and economic evaluation of undiscovered uranium endowment and resources

International Nuclear Information System (INIS)

1992-01-01

The present Instruction Manual was prepared as part of a programme of the International Atomic Energy Agency to supply the international uranium community with standard guides for a number of topics related to uranium resource assessment and supply. The quantitative estimation of undiscovered resources and endowments aims at supplying data on potential mineral resources; these data are needed to compare long term projections with one another and to assess the mineral supplies to be obtained from elsewhere. These objectives have relatively recently been supplemented by the concern of land managers and national policy planners to assess the potential of certain lands before the constitution of national parks and other areas reserved from mineral exploration and development. 88 refs, 28 figs, 33 tabs

This work investigates the permissibility and viability of property rights on the celestial bodies, particularly the extraterrestrial aspects of land and mineral resources ownership. In lay terms, it aims to find an answer to the question "Who owns the Moon?" After critically analyzing and dismantling with legal arguments the trivial issue of sale of extraterrestrial real estate, the book addresses the apparent silence of the law in the field of landed property in outer space, scrutinizing whether the factual situation on the extraterrestrial realms calls for legal regulations. The legal status of asteroids and the relationship between appropriation under international law and civil law appropriation are duly examined, as well as different property patterns – such as the commons regime, the Common Heritage of the Mankind, and the Frontier paradigm.

2016-01-01

Tamil Nadu, the southernmost state with second longest coast line in India has many placer heavy mineral deposits. These deposits contain economically important light heavy minerals like ilmenite, rutile, leucoxene, monazite, zircon, garnet, sillimanite, kyanite and non-economic minerals like pyroxenes, amphiboles and magnetite along with associated accessory minerals like staurolite, epidote, spinel, biotite and tourmaline. Geologically, granulitic rocks, principally Khondalites (garnet-sillimanite-graphite gneisses), charnockites and granitic gneisses bordered by sedimentary rocks are exposed along the eastern coastal plains of the Tamil Nadu. The principal highland areas, as for example, Shavaroys, Nilgiris, Palni-Kodaikanal Hills and Cardomom hills consists primarily of Charnockites. The margins of highland show a gradation into less metamorphosed rocks generally of amphibolite facies. The khondalites are found south of Kodaikanal massif. Anorthosites and layered mafic complexes occur at Sittampundi, Kadavur areas. Alkaline rocks and carbonatites are prominent at Simalpatti, Sevattur and Sivamalai. Coastal sedimentaries include, Gondwanas, Cretaceous, Tertiary and Quaternary rocks along with lateritic soils and beach sands

Resources from waste : integrated resource management phase 1 study report

International Nuclear Information System (INIS)

Corps, C.; Salter, S.; Lucey, P.; O'Riordan, J.

2008-01-01

Integrated resource management (IRM) of municipal waste streams and water systems requires a structured analysis of options that consider environmental aspects such as greenhouse gases, carbon taxes and credits. Each option's inputs and outputs are assessed to determine the net highest and best use and value. IRM focuses on resource recovery and extracting maximum value. It considers the overall net impact on the taxpayer and requires the integration of liquid and solid waste streams to maximize values for recovering energy in the form of biofuels, heat, minerals, water and reducing electricity demand. IRM is linked to water management through reuse of treated water for groundwater recharge and to offset potable water use for non-potable purposes such as irrigation, including potential commercial use, which contributes to maintaining or improving the health of watersheds. This report presented a conceptual design for the application of IRM in the province of British Columbia (BC) and analyzed its potential contribution to the provincial climate change agenda. The report discussed traditional waste management, the IRM approach, and resource recovery technology and opportunities. The business case for IRM in BC was also outlined. It was concluded that IRM has the potential to be a viable solution to water, solid and liquid waste management that should be less expensive, result in fewer environmental impacts, and provide greater flexibility than traditional approaches to waste management. 63 refs., 17 tabs., 21 figs., 10 appendices

From Field to the Web: Management and Publication of Geoscience Samples in CSIRO Mineral Resources

Devaraju, A.; Klump, J. F.; Tey, V.; Fraser, R.; Reid, N.; Brown, A.; Golodoniuc, P.

2016-12-01

Inaccessible samples are an obstacle to the reproducibility of research and may cause waste of time and resources through duplication of sample collection and management. Within the Commonwealth Scientific and Industrial Research Organisation (CSIRO) Mineral Resources there are various research communities who collect or generate physical samples as part of their field studies and analytical processes. Materials can be varied and could be rock, soil, plant materials, water, and even synthetic materials. Given the wide range of applications in CSIRO, each researcher or project may follow their own method of collecting, curating and documenting samples. In many cases samples and their documentation are often only available to the sample collector. For example, the Australian Resources Research Centre stores rock samples and research collections dating as far back as the 1970s. Collecting these samples again would be prohibitively expensive and in some cases impossible because the site has been mined out. These samples would not be easily discoverable by others without an online sample catalog. We identify some of the organizational and technical challenges to provide unambiguous and systematic access to geoscience samples, and present their solutions (e.g., workflow, persistent identifier and tools). We present the workflow starting from field sampling to sample publication on the Web, and describe how the International Geo Sample Number (IGSN) can be applied to identify samples along the process. In our test case geoscientific samples are collected as part of the Capricorn Distal Footprints project, a collaboration project between the CSIRO, the Geological Survey of Western Australia, academic institutions and industry partners. We conclude by summarizing the values of our solutions in terms of sample management and publication.

Very little information is available to IAEA on the geology and uranium potential of Syria. In 1975 a contract was awarded to Huntings Geology and Geophysics Ltd by the Ministry of Petroleum and Mineral Resources to carry out a study of the country's mineral resources with particular reference to phosphate uranium, chrome and industrial materials. The results of this survey are not known. Apart from the assumption of some possibility of uranium recovery as a by-product from phosphate production it is assumed that the Speculative Potential is likely to be less than 1000 tonnes uranium.

Uncertainty Estimate in Resources Assessment: A Geostatistical Contribution

International Nuclear Information System (INIS)

Souza, Luis Eduardo de; Costa, Joao Felipe C. L.; Koppe, Jair C.

2004-01-01

For many decades the mining industry regarded resources/reserves estimation and classification as a mere calculation requiring basic mathematical and geological knowledge. Most methods were based on geometrical procedures and spatial data distribution. Therefore, uncertainty associated with tonnages and grades either were ignored or mishandled, although various mining codes require a measure of confidence in the values reported. Traditional methods fail in reporting the level of confidence in the quantities and grades. Conversely, kriging is known to provide the best estimate and its associated variance. Among kriging methods, Ordinary Kriging (OK) probably is the most widely used one for mineral resource/reserve estimation, mainly because of its robustness and its facility in uncertainty assessment by using the kriging variance. It also is known that OK variance is unable to recognize local data variability, an important issue when heterogeneous mineral deposits with higher and poorer grade zones are being evaluated. Alternatively, stochastic simulation are used to build local or global uncertainty about a geological attribute respecting its statistical moments. This study investigates methods capable of incorporating uncertainty to the estimates of resources and reserves via OK and sequential gaussian and sequential indicator simulation The results showed that for the type of mineralization studied all methods classified the tonnages similarly. The methods are illustrated using an exploration drill hole data sets from a large Brazilian coal deposit

Long-range economic development in Central America will depend in large part on production of indigenous mineral, energy, and water resources and on mitigation of the disastrous effects of geologic and hydrologic hazards such as landslides, earthquakes, volcanic eruptions, and floods. The region has six world-class metal mines at present as well as additional evidence of widespread mineralization. Systematic investigations using modern mineral exploration techniques should reveal more mineral deposits suitable for development. Widespread evidence of lignite and geothermal resources suggests that intensive studies could identify producible energy sources in most Central American countries. Water supply and water quality vary greatly from country to country. Local problems of ground- and surface-water availability and of contamination create a need for systematic programs to provide better hydrologic data, capital improvements, and management. Disastrous earthquakes have destroyed or severely damaged many cities in Central America. Volcanic eruptions, landslides, mudflows, and floods have devastated most of the Pacific side of Central America at one time or another. A regional approach to earthquake, volcano, and flood-risk analysis and monitoring, using modern technology and concepts, would provide the facilities and means for acquiring knowledge necessary to reduce future losses. All Central American countries need to strengthen institutions and programs dealing with earth and water resources and natural hazards. Some of these needs may be satisfied through existing or pending projects and technical and economic assistance from U.S. or other sources. The need for a comprehensive study of the natural resources of Central America and the requirements for their development is evident. The U.S. Caribbean Basin Initiative offers both an excellent opportunity for a regional approach to these pervasive problems and an opportunity for international cooperation.

This research paper is about the depletion of Energy resources being a huge problem facing the world at this time. As available energy sources are coming to a shortage and measures are be taken in order to conserve the irreplaceable energy resources that leads to sustainability and fair use of energy sources for future generations. Alternative energy sources are being sought; however no other energy source is able to provide even a fraction of energy as that of fossil fuels. Use of the alternative energy resources like wind corridors (Sindh and Baluchistan), fair use of Hydro energy (past monsoon flooding can produce enough energy that may available for next century). Uranium Resources which are enough for centuries energy production in Pakistan (Dhok Pathan Formation) lying in Siwalick series from Pliocene to Pleistocene. Among all of these, my focus is about energy from mineral fuels like Uranium from Sandstone hosted deposits in Pakistan (Siwalik Series in Pakistan). A number of uranium bearing mineralized horizons are present in the upper part of the Dhok Pathan Formation. These horizons have secondary uranium mineral carnotite and other ores. Uranium mineralization is widely distributed throughout the Siwaliks The purpose of this paper was to introduce the use of alternative energy sources in Pakistan which are present in enough amounts by nature. Pakistan is blessed with wealth of natural resources. Unfortunately, Pakistan is totally depending on non renewable energy resource. There are three main types of fossil fuels: coal, oil and natural gas. After food, fossil fuel is humanity's most important source of energy. Pakistan is among the most gas dependent economies of the world. Use of fossil fuel for energy will not only increase the demand of more fossils but it has also extreme effects on climate as well as direct and indirect effects to humans. These entire remedial thinking can only be possible if you try to use alternative energy resources rather than

Based on analyzing the current situation of uranium resources and exploration effort in East China, the main existing problems, technical thought and countermeasure for the future exploration in East China are discussed in this paper. The degree of both uranium exploration and study in East China is relatively high, philosophy of scientific mineral-prospecting should be established in the new round of mineral prospecting. Under guidance of metallogenic theory of large mineralization cluster area and uranium metallogenic theory of multi-sources, previous data and research achievement should be analyzed and summarized. With the help of metallogenic model, useful methods and means should be applied to set up exploration model in order to realize news phase of model exploration, comprehensive exploration, 3D exploration and quantitative exploration. Efficiency of exploration of uranium resources should be strugglingly increased. High profitable uranium resources will be actively found with rich, shallow, near and easy features. The prospecting targets and strategy reserves of uranium resources will be increased in East China. (authors)

Uranium resources evaluation model as an exploration tool

International Nuclear Information System (INIS)

Ruzicka, V.

1976-01-01

Evaluation of uranium resources, as conducted by the Uranium Resources Evaluation Section of the Geological Survey of Canada, comprises operations analogous with those performed during the preparatory stages of uranium exploration. The uranium resources evaluation model, simulating the estimation process, can be divided into four steps. The first step includes definition of major areas and ''unit subdivisions'' for which geological data are gathered, coded, computerized and retrieved. Selection of these areas and ''unit subdivisions'' is based on a preliminary appraisal of their favourability for uranium mineralization. The second step includes analyses of the data, definition of factors controlling uranium minearlization, classification of uranium occurrences into genetic types, and final delineation of favourable areas; this step corresponds to the selection of targets for uranium exploration. The third step includes geological field work; it is equivalent to geological reconnaissance in exploration. The fourth step comprises computation of resources; the preliminary evaluation techniques in the exploration are, as a rule, analogous with the simplest methods employed in the resource evaluation. The uranium resources evaluation model can be conceptually applied for decision-making during exploration or for formulation of exploration strategy using the quantified data as weighting factors.

Full Text Available For many countries and regions (both in Russia and abroad, natural resources are the crucial factor for socio-economic development. The role and significance of natural resources in the economy of different areas substantially depend on the institutional environment, including the resource regime. Today, we have a qualitative complication of conditions for mineral resources exploitation, we start to develop new, non-traditional types of resources, which haven’t been available (or demanded earlier for the economic and technological reasons. The changes in the characteristics of natural objects, as well as the increasing of uncertainty in the resource sector, actualize the search for alternatives of the development of resource-type regions and for the elaboration of appropriate strategies. In new conditions of resource regions, it is necessary to place emphasis on the aspects of expanded specific understanding of inclusiveness. It implies the possibility of active participation of regional authorities in the management and regulation of the mineral complex, as well as their involvement in the development of the association of a wide range of communities. These communities consist of the organizations representing the interests of indigenous peoples as well as professional communities: industry associations, environmental organizations, representatives of the innovation industry. Modern approaches to the elaboration of strategic directions for the resource regions development (primarily based on the development of the mineral industry should be based on sustainable development principles, the principles of inclusiveness and the need for innovations. As a result of the convergence of these characteristics, a new socio-economic concept is formed. This concept can be defined as the harmonious development that is extremely important for the Russian regions. The proposed approach can be used for the elaboration of strategic alternatives of the

The goals of this study were to identify pupal parasitoids of the asparagus miner, Ophiomyia simplex Loew (Diptera: Agromyzidae), and examine the effect of different diets and floral resources on the lifespan of adult asparagus miners and their parasitoids. We also measured the effect of parasitism on stem damage caused by the asparagus miner. The identity and abundance of the parasitoids of the asparagus miner were determined in asparagus fields in Michigan from weekly asparagus miner pupal collections during the 2010-2013 seasons. Twelve species of hymenopterous parasitoids were reared from asparagus miner pupae, including Chorebus rondanii (Giard) (Ichneumonoidea: Braconidae), 10 species in three families of Chalcidoidea, and one species of Bethylidae (Chrysidoidea), that represent new host records for the asparagus miner. C. rondanii and Thinodytes cephalon (Walker) (Pteromalidae) were the most common parasitoids. The effects of different diets and flowers on the lifespan of the pest and parasitoid adults were also evaluated. Buckwheat resulted in the shortest life span for the asparagus miner, whereas Riddell's goldenrod significantly increased its lifespan relative to the control. Parasitoid lifespan was doubled when individuals were fed sugar-rich diets. In the field, parasitoids preferred stems that contained more pupae and damage. The two most commonly reared parasitoids should be considered as targets for future conservation biological control efforts of the asparagus miner.

CGI Interoperability Working Group activities during 2012 include deployment of services using the GeoSciML-Portrayal schema, addition of new vocabularies to support properties added in version 3.0, improvements to server software for deploying services, introduction of EarthResourceML v.2 for mineral resources, and collaboration with the IUSS on a markup language for soils information. GeoSciML and EarthResourceML have been used as the basis for the INSPIRE Geology and Mineral Resources specifications respectively. GeoSciML-Portrayal is an OGC GML simple-feature application schema for presentation of geologic map unit, contact, and shear displacement structure (fault and ductile shear zone) descriptions in web map services. Use of standard vocabularies for geologic age and lithology enables map services using shared legends to achieve visual harmonization of maps provided by different services. New vocabularies have been added to the collection of CGI vocabularies provided to support interoperable GeoSciML services, and can be accessed through http://resource.geosciml.org. Concept URIs can be dereferenced to obtain SKOS rdf or html representations using the SISSVoc vocabulary service. New releases of the FOSS GeoServer application greatly improve support for complex XML feature schemas like GeoSciML, and the ArcGIS for INSPIRE extension implements similar complex feature support for ArcGIS Server. These improved server implementations greatly facilitate deploying GeoSciML services. EarthResourceML v2 adds features for information related to mining activities. SoilML provides an interchange format for soil material, soil profile, and terrain information. Work is underway to add GeoSciML to the portfolio of Open Geospatial Consortium (OGC) specifications.

New Opportunities to Expand Information on Intense-Strained State of the Earth's Crust in the Areas of Development Mineral Resources During Monitoring Creation

2017-01-01

Full Text Available It is established that new safe and pollution-free technologies of development of Kuzbass coal deposits should be based on new knowledge of development geodynamic and technogenic processes in exploration of mineral resources. Such information is impossible without formation of new models of deformations of the earth crust blocks. Now in traditional technologies of geomechanical ensuring development of mineral resources the main characteristic is the information about the kinematics of these processes. A comprehensive approach which beginning is development of the theory for justification of scale of the explored territory and establishment of uniform integral parameters of a strained state of blocks of crust. Justification of scale of the explored territory defines effectiveness of expenses. Establishment of uniform integral parameters of a strained state of crustal blocks characterizes the new level of information exchange between sciences about Earth and geomechanics. Practical use of the specified theory consists of assessment of geodynamic danger at development of coal fields.

Economic profit could be influenced by economic rents. However natural resource rents provided different impact on the economic growth or economic profit. The main focus of the study was to evaluate the economic growth as function of natural resource rents. For such a purpose machine learning approach, artificial neural network, was used. The used natural resource rents were coal rents, forest rents, mineral rents, natural gas rents and oil rents. Based on the results it is concluded that the machine learning approach could be used as the tool for the economic growth evaluation as function of natural resource rents. Moreover the more advanced approaches should be incorporated to improve more the forecasting accuracy.

Marine mineral resources of Pacific Islands - a review of the Exclusive Economic Zones of islands of U.S. affiliation, excluding the State of Hawaii

Science.gov (United States)

Hein, James R.; McIntyre, Brandie R.; Piper, David Z.

2005-01-01

The United States Exclusive Economic Zone (EEZ) was established in 1983 and comprises all marine areas within 200 nautical miles (370 kilometers) of the nearest U.S. land. This vast area of 3.38 million square nautical miles (11.6 million square kilometers) is about 20 percent greater than the entire land area of the United States. The resource potential of the vast mineral deposits that occur within the U.S. EEZ is unknown, despite field studies that have taken place during the past 25 years. Since about 1975, information on marine mineral deposits has been obtained by numerous research cruises to the Pacific Ocean by the U.S. Geological Survey (USGS), the U.S. National Oceanic and Atmospheric Administration (NOAA), equivalent government agencies in Germany, Canada, France, Russia, Japan, China, South Korea, Australia, and New Zealand, and by academic researchers from all of these nations. Although most of the cruises by other nations explored areas outside the U.S. EEZ, information gained from those studies can aid in the evaluation of the mineral potential in the U.S. EEZ. However, the global effort remains inadequate to allow for the quantitative evaluation of mineral resources contained within the EEZ of nations or within international regions of the oceans.

On geothermal resources of India. Geotectonic aspects and recent developments

Energy Technology Data Exchange (ETDEWEB)

Gupta, M L [National Geophysical Research Inst., Hyderabad (India)

1988-11-10

Research programs launched for exploration and development of the geothermal energy in India, since the 1973-1974 oil embargo, have led to the identification of many potential areas for geothermal resources. Resources comprise high/intermediate/low temperature hydrothermal convection and hot water aquifer systems, geopressured geothermal system and conduction-dominated regimes. Location and properties of these geothermal systems are controlled by the geodynamic and tectonic characteristics of the Indian continental lithosphere Main sectors for the utilization of India's proved and identified geothermal resources are the power generation, space heating, green house cultivation, aquaculture, poultry, sheep breeding, mineral processing, mushroom raising, processing of farm and forest produce, refrigeration, tourism, health-resorts and mineral water bottling. The R and D efforts have given some encouraging results. Geothermal resources of India, although primarily are of medium to low grade, could supplement, to a great extent, direct heat energy needs and may also provide electricity to some of the remote hilly areas. Development of geothermal energy sources in India is likely to get some more attention, with the setting up of separate departments and agencies, by various Provincial Governments, for R and D backing toward the alternate sources of energy.

Natural resources and government revenue : recent trends in Saskatchewan

International Nuclear Information System (INIS)

Warnock, J.W.

2005-01-01

This document discusses recent trends in Saskatchewan regarding natural resources and government revenue. It discusses the history of politics in terms of government expenditure and investment in natural resources; the polarization between urban and rural areas; natural resources and capital accumulation and economic rent and royalties from resource extraction. The document also discusses several industries in Saskatchewan including petroleum, natural gas discovery and extraction. Uranium and coal mining activities were also documented along with other minerals such as gold, diamonds, and sodium sulphate. The article focused on the share of economic rent going to the general public compared to the amount going to private corporations. The author argued that with rising prices for natural resources, the provincial government has been transferring billions of dollars of resources rent to private investors by reducing royalties, fees and taxes. This has resulted in less revenue for the provincial government to spend on programs such as health, education and public services. The author suggested that concerted efforts must be put forward to put the issue of the public role in resource development back on the government agenda. 99 refs., 7 tabs

Every two years, Bonneville Power Administration (BPA) prepares a Resource Program which identifies the resource actions BPA will take to meet its obligation to serve the forecasted power requirements of its customers. The Resource Program's Environmental Impact Statement (RPEIS) is a programmatic environmental document which will support decisions made in several future Resource Programs. Environmental documents tiered to the EIS may be prepared on a site-specific basis. The RPEIS includes a description of the environmental effects and mitigation for the various resource types available in order to evaluate the trade-offs among them. It also assesses the environmental impacts of adding thirteen alternative combinations of resources to the existing power system. This report contains the appendices to the RPEIS

A proposed United States resource classification system

International Nuclear Information System (INIS)

Masters, C.D.

1980-01-01

Energy is a world-wide problem calling for world-wide communication to resolve the many supply and distribution problems. Essential to a communication problem are a definition and comparability of elements being communicated. The US Geological Survey, with the co-operation of the US Bureau of Mines and the US Department of Energy, has devised a classification system for all mineral resources, the principles of which, it is felt, offer the possibility of world communication. At present several other systems, extant or under development (Potential Gas Committee of the USA, United Nations Resource Committee, and the American Society of Testing and Materials) are internally consistent and provide easy communication linkage. The system in use by the uranium community in the United States of America, however, ties resource quantities to forward-cost dollar values rendering them inconsistent with other classifications and therefore not comparable. This paper develops the rationale for the new USGS resource classification and notes its benefits relative to a forward-cost classification and its relationship specifically to other current classifications.

Prokudina, Marina; Zhironkina, Olga; Kalinina, Oksana; Gasanov, Magerram; Agafonov, Felix

2017-11-01

In the Russian economy, the world leadership in the extraction of different mineral resources is combined with the potential for their processing and a significant scientific sector. Innovative development of raw materials extraction is impossible without the parallel technological modernization of the high-tech sector. In general, the complex of these processes is a neo-industrialization of the economy. Neo-industrially oriented transformation of the economy reflects complex changes in its structure, the transformation of established stable relationships between various elements of the system of social production that determine macroeconomic proportions. Neo-industrial transformations come along with the modification of economic relations associated with investments, innovations, labor and income distribution, with the process of locating productive forces and regulating the economy by the government. Neo-industrialization of economy is not only significant changes in its technological and reproductive structure (the development of high-tech industries, the integration of science and industry), but, above all, the implementation of a system structural policy of innovative development of raw material industry and the recovery of manufacturing industries on a new technological basis.

Preface: Terrestrial Fieldwork to Support in situ Resource Utilization (ISRU) and Robotic Resource Prospecting for Future Activities in Space

Science.gov (United States)

Sanders, Gerald B.

2015-05-01

Finding, extracting, and using resources at the site of robotic and human exploration activities holds the promise of enabling sustainable and affordable exploration of the Moon, Mars, and asteroids, and eventually allow humans to expand their economy and habitation beyond the surface of the Earth. Commonly referred to as in situ Resource Utilization (ISRU), mineral and volatile resources found in space can be converted into oxygen, water, metals, fuels, and manufacturing and construction materials (such as plastics and concrete) for transportation, power, life support, habitation construction, and part/logistics manufacturing applications. For every kilogram of payload landed on the surface of the Moon or Mars, 7.5-11 kg of payload (mostly propellant) needs to be launched into low Earth orbit. Therefore, besides promising long-term self-sufficiency and infrastructure growth, ISRU can provide significant reductions in launch costs and the number of launches required. Key to being able to use space resources is knowing where they are located, how much is there, and how the resources are distributed. While ISRU holds great promise, it has also never been demonstrated in an actual space mission. Therefore, operations and hardware associated with each ISRU prospecting, excavation, transportation, and processing step must be examined, tested, and finally integrated to enable the end goal of using space resources in future human space missions.

Remote sensing strategies for global resource exploration and environmental management

Science.gov (United States)

Henderson, Frederick B.

Since 1972, satellite remote sensing, when integrated with other exploration techniques, has demonstrated operational exploration and engineering cost savings and reduced exploration risks through improved geological mapping. Land and ocean remote sensing satellite systems under development for the 1990's by the United States, France, Japan, Canada, ESA, Russia, China, and others, will significantly increase our ability to explore for, develop, and manage energy and mineral resources worldwide. A major difference between these systems is the "Open Skies" and "Non-Discriminatory Access to Data" policies as have been practiced by the U.S. and France and the restrictive nationalistic data policies as have been practiced by Russia and India. Global exploration will use satellite remote sensing to better map regional structural and basin-like features that control the distribution of energy and mineral resources. Improved sensors will better map lithologic and stratigraphic units and identify alteration effects in rocks, soils, and vegetation cover indicative of undiscovered subsurface resources. These same sensors will also map and monitor resource development. The use of satellite remote sensing data will grow substantially through increasing integration with other geophysical, geochemical, and geologic data using improved geographic information systems (GIS). International exploration will focus on underdeveloped countries rather than on mature exploration areas such as the United States, Europe, and Japan. Energy and mineral companies and government agencies in these countries and others will utilize available remote sensing data to acquire economic intelligence on global resources. If the "Non-Discriminatory Access to Data" principle is observed by satellite producing countries, exploration will remain competitive "on the ground". In this manner, remote sensing technology will continue to be developed to better explore for and manage the world's needed resources

Electrostatic Beneficiation of Lunar Regolith: Applications in In-Situ Resource Utilization

Science.gov (United States)

Trigwell, Steve; Captain, James; Weis, Kyle; Quinn, Jacqueline

2011-01-01

Upon returning to the moon, or further a field such as Mars, presents enormous challenges in sustaining life for extended periods of time far beyond the few days the astronauts experienced on the moon during the Apollo missions. A stay on Mars is envisioned to last several months, and it would be cost prohibitive to take all the requirements for such a stay from earth. Therefore, future exploration missions will be required to be self-sufficient and utilize the resources available at the mission site to sustain human occupation. Such an exercise is currently the focus of intense research at NASA under the In-situ Resource Utilization (ISRU) program. As well as oxygen and water necessary for human life, resources for providing building materials for habitats, radiation protection, and landing/launch pads are required. All these materials can be provided by the regolith present on the surface as it contains sufficient minerals and metals oxides to meet the requirements. However, before processing, it would be cost effective if the regolith could be enriched in the mineral(s) of interest. This can be achieved by electrostatic beneficiation in which tribocharged mineral particles are separated out and the feedstock enriched or depleted as required. The results of electrostatic beneficiation of lunar simulants and actual Apollo regolith, in lunar high vacuum are reported in which various degrees of efficient particle separation and mineral enrichment up to a few hundred percent were achieved.

Securing Energy and Mineral Resources for China: Debating the role of markets

International Nuclear Information System (INIS)

Seaman, John

2015-10-01

This paper examines how China seeks to secure access to an ever growing level of natural resources from overseas. In its quest for resources necessary to fuel its economy, does China seek to bolster the development of international markets, or rather to procure resources in a more mercantilist fashion? China's varied behavior in a broad range of resource markets suggest that there is no guiding principle that pre-ordains a common approach today. Three cases - oil, iron ore and rare earths - show three different Chinese approaches to issues of resource procurement and allocation. In the case of oil, China has shown an increasing acceptance of market principles over the course of the last decade. In iron ore, meanwhile, China's strategy to gain a strong negotiating position within a pre-existing, closed system was ultimately upended by its inability to control its own market actors. The result was the opening-up of a more fluid market. Finally, the rare earth case provides an example of China's approach when it controls global production (albeit production within its own borders). China has been willing to contravene market principles in the rare earth trade either for diplomatic gains or to incite transfers of foreign technology to China. Nevertheless, it has also shown that it is not willing to sacrifice its participation in the broader system of international trade rules as laid out in the World Trade Organization (WTO). Ultimately, while China's growing need for imported raw materials certainly poses a number of challenges, many of the concerns about China are exaggerated, or overlook emerging trends in the way Chinese companies do business overseas. In particular, fears of Chinese 'mercantilism' are tempered by the fact that Chinese companies have in practice served to reinforce and even improve, rather than contravene international market mechanisms for trade in resources. Skepticism of international market principles in China has seemingly waned over time, and

International Uranium Resources Evaluation Project (IUREP) national favourability studies: Thailand

International Nuclear Information System (INIS)

1977-08-01

Thailand is a country with an area of 514?000 square kilometres situated in the centre of continental south-east Asia, The geology of Thailand is very varied with sedimentary formations ranging from Cambrian to Quaternary in age and including sandstones, shales, limestones of many varieties. Among the igneous rocks, granites are very important and rhyolites, tuffs diorites, basalts and ultrabasic rocks also exist. Tin is the most important mineral occurrence. Available information on the geology and mineral resources suggests that the country may contain significant resources of radioactive minerals. Favourable potential host types are; 1) uranium and thorium in monazite in beach sands and tin placer deposits; 2) uranium in sandstones, principally in Jurassic sandstones of the Khorat Plateau; 3) uranium in Tertiary lignite deposits; 4) uranium in veins in granites; 5) uranium related to fluorite deposits; 6) uranium in black shales and phosphates. Uranium mineralization in sedimentary rocks at Phu Wieng was discovered in 1970. The area has been radiometrically grid mapped and limited shallow drilling has shown continuity.of the narrow, carbonaceous, conglomeratic sandstone host bed. No uranium reserves or resources can be stated at the present time, but the favourable geology of the Khorat Plateau, the known uranium occurrence and the very small exploration coverage is possibly indicative of a good future potential. The Speculative Potential is estimated to be between 1000 and 10,000 tonnes uranium. (author)

Mineral resources and energy. Report by the 'Soil and underground' group of the Ancre Alliance

International Nuclear Information System (INIS)

2015-06-01

After comments on the growth of the world consumption of raw materials, on the relocation of productions and on the loss of interest by industrialized countries in mineral resources and their dependency, and a discussion of the relationship between energy and mineral raw materials, this study proposes an assessment and a discussion of energy needs for mining and metal industries. In the next part, needs in raw materials for the energy sector are analysed and discussed with respect to their field of application, to their intensity, to energy scenarios, and to application to research. The value chain is then analysed as well as its risks which can be political, industrial, related to infrastructures, economic, environmental, geological, technical, or social. Recycling capacities and the potential of substitution are then addressed. Themes and axis of research are identified for the assessment of needs, social acceptability, geology and exploration, mining, ore processing and metal industry, recycling, and substitution

Resource acquisition policy: Multiple account evaluation of electricity resource alternatives [and] resource acquisition strategy

International Nuclear Information System (INIS)

1994-06-01

British Columbia Hydro has been directed by the provincial government to develop evaluation procedures to rank electricity resource alternatives in terms of their social benefits and costs, and to acquire resources on the basis of need. The current state of development of social costing at BC Hydro is detailed along with its application to the multiple account evaluation of resources. In this evaluation, BC Hydro's corporate costs, customer cost, transfer payments to the province, direct costs incurred by provincial or regional governments or other Crown agences, direct environmental impact costs from air emissions and land/water use, community and social impact costs, and economic development impacts are taken into account. The BC Hydro resource acquisition strategy is also described as it was developed in response to provincial policy on electricity supply from independent power producers. This strategy includes a determination of need, a decision to acquire need-determined resources either by itself or from a private sector developer, and decisions to acquire resources in advance of need for reasons such as economic opportunity, long-term strategies, or load displacement. Background information is included on calculation of air emissions costs. An illustrative example is provided of the multiple account evaluation of several types of resource projects. 1 fig., 5 tabs

The Republic of Korea, occupies the southern end of the Korean peninsula. It has a long history of mining and mineral production, and has an active and fairly well equipped Geological Survey. The country in general is quite highly mineralized with many minerals including uranium although there has been no uranium production from it yet. Uranium occurs in granites, schists, and in black carbonaceous shales. The Korean Geological survey has estimated that one ore body contains 650 tonnes U in 1,600,000 tons of ore at an average grade of 0.047 percent U 3 O 8 . Many recent reports also indicate very large resources of uranium in very low grade ranges. The uranium potential for the Republic of Korea is considered in Category 2 (1,000 - 10,000 tonnes U) in the normal IUREP context. However, a very large resource may exist in the very low grades in black shales of the country. This resource is considered as in category 6 (500,000 to 1,000,000 tonnes U). (author)

We, for example, have used them for quantitation of proteins on "reverse-phase" protein lysate arrays. For those studies, we quality-controlled > 600 available monoclonal antibodies and also needed to develop precise information on the genes that encode their antigens. Translation among the various protein and gene identifier types proved non-trivial because of one-to-many and many-to-one relationships. To organize the antibody, protein, and gene information, we initially developed a relational database in Filemaker for our own use. When it became apparent that the information would be useful to many other researchers faced with the need to choose or characterize antibodies, we developed it further as AbMiner, a fully relational web-based database under MySQL, programmed in Java.

Full Text Available Minable rock phosphate is a finite resource. Replacing mineral phosphorus (P fertilizer with P-rich secondary resources is one way to manage P more efficiently, but the importance of physicochemical and microbial soil processes induced by secondary resources for plant P uptake are still poorly understood. Using radioactive labelling techniques, the fertilization effects of dairy manure, fish sludge, meat bone meal and wood ash were studied as P uptake by barley after 44 days and compared with those of water-soluble mineral P (MinP and an unfertilized control (NoP in a pot experiment with an agricultural soil containing little available P at two soil pH levels, approximately pH 5.3 (unlimed soil and pH 6.2 (limed soil. In a parallel incubation experiment, the effects of the secondary resources on physicochemical and microbial soil processes were studied. The results showed that the relative agronomic efficiency compared with MinP decreased in the order: manure ≥ fish sludge ≥ wood ash ≥ meat bone meal. The solubility of inorganic P in secondary resources was the main driver for P uptake by barley (Hordeum vulgare. The effects of secondary resources on physicochemical and microbial soil processes were of little overall importance. Application of organic carbon with manure resulted in microbial P immobilisation and decreased uptake by barley of P derived from the soil. On both soils, P uptake by barley was best explained by a positive linear relationship with the H2O + NaHCO3-soluble inorganic P fraction in fertilizers, or by a linear negative relationship with the HCl-soluble inorganic P fraction in fertilizers.

The investigation and evaluation of groundwater resources refers to the analysis of groundwater quantity, quality, spatial-temporal property and exploitation status. Based on the collected data and field investigation, the groundwater resources in plain and hilly area of Juxian were calculated by replenishment method, discharge method and comprehensive infiltration coefficient method, and the groundwater quality was analyzed and evaluated. The conclusions are as follows: (1) The amount of groundwater resources is 224.940 million m3/a, including 89.585 million m3/a of plain area and 142.523 million m3/a of hilly area respectively. (2) The allowable yield of groundwater is about 162.948 million m3/a, in which the amounts in the plain area and the hilly area are 74 .585million m3/a and 88.363 million m3/a, respectively. (3) The pH value of groundwater ranges from 6.5∼7.5 and the degree of mineralization of groundwater was lower than 1 g/L at most. In addition, the total hardness varies from 150 mg/L to 450 mg/L in plain area and 300 mg/L to 550 mg/L in hilly area, respectively. The investigation and evaluation of groundwater resources was of great significance in ensuring the sustainable development of groundwater resources, establishing the scheme of groundwater resources exploitation and utilization.

Tungsten-bearing rocks in the Benton Range Roadless Area occur in tactite lenses within the Paleozoic metasedimentary units that surround and are intruded by Triassic granodiorite of the Benton Range. High anomalous tungsten values were found in the southern part of the study area. Quartz-vein deposits with copper, lead, zinc, and silver may occur within the Jurassic granitic rock in the northwestern part of the area. Stream-sediment and panned-concentrate samples from the northwestern part of the roadless area, reveal anomalous values in a number of elements. Some of these elements are indicative of mineral suites that form by hydrothermal alteration and are potential metallic-ore producers. Metals having anomalous values are antimony, copper, lead, molybdenum, tin, and zinc; their presence suggests the potential for deposits of the lead-zinc-silver or copper-molybdenum type. Molybdenum and lead were identified by geochemical sampling as having low to moderate potential in the roadless area. An estimated 190,000 tons (172,000 t) of subeconomic gold and silver resources are inside the roadless area at the Gold Crown, Gold Webb, and Gold Wedge mines; another 60,000 tons (54,000 t) of subeconomic gold and silver resources are just outside the area at the Tower, Gold Webb, and Gold Wedge mines (table 1). Most of the lode gold and silver deposits are in quartz veins and shear zones. Minor amounts of copper, lead, and zinc occur in some gold deposits. About 2,240 oz (70 kg) of gold, 8,450 oz (260 kg) of silver, and 4,600 lb of lead (2,090 kg) have been produced from the roadless area. In addition, 7,257 oz (226 kg) of gold and 350 oz (11 kg) silver were produced at the Tower mine, near the area.

Energy and other resources

International Nuclear Information System (INIS)

Rosenqvist, I.Th.

It is pointed out that inorganic mineral raw materials, usually called ores, do not form a separate geological class, with a strictly defined limit in quantity. The raw materials are in fact present in continuously variable concentrations and amounts with differing geographical distribution. It is only the richest occurrences which are regarded as resources and exploited. The cone concept of available material is presented, where the amount of material available increases as the work invested is increased, but the profitable ore is represented only by the apex of the cone. In applying this idea to fossil fuels the concept must be modified to a 'pear', since the energy invested in retrieving the fuel must not exceed the energy content of the fuel. Renewable energy sources are also discussed, and it is pointed out that geothermal energy should not be regarded as renewable. It is pointed out, too, that, unless breeder reactors are introduced, the fossil fuel resources will give more energy than uranium, and probably cheaper. (JIW)Ψ

The United Nations have studied how the oil and gas resource classification developed jointly by the SPE, the World Petroleum Congress (WPC) and the American Association of Petroleum Geologists (AAPG) could be harmonized with the United Nations Framework Classification (UNFC) for Solid Fuel and Mineral Resources (1). The United Nations has continued to build on this and other works, with support from many relevant international organizations, with the objective of updating the UNFC to apply to the extractive industries. The result is the United Nations Framework Classification for Energy and Mineral Resources (2) that this paper will present. Reserves and resources are categorized with respect to three sets of criteria: ??? Economic and commercial viability ??? Field project status and feasibility ??? The level of geologic knowledge The field project status criteria are readily recognized as the ones highlighted in the SPE/WPC/AAPG classification system of 2000. The geologic criteria absorb the rich traditions that form the primary basis for the Russian classification system, and the ones used to delimit, in part, proved reserves. Economic and commercial criteria facilitate the use of the classification in general, and reflect the commercial considerations used to delimit proved reserves in particular. The classification system will help to develop a common understanding of reserves and resources for all the extractive industries and will assist: ??? International and national resources management to secure supplies; ??? Industries' management of business processes to achieve efficiency in exploration and production; and ??? An appropriate basis for documenting the value of reserves and resources in financial statements.

Lithium Resources for the 21st Century

Kesler, S.; Gruber, P.; Medina, P.; Keolian, G.; Everson, M. P.; Wallington, T.

2011-12-01

Lithium is an important industrial compound and the principal component of high energy-density batteries. Because it is the lightest solid element, these batteries are widely used in consumer electronics and are expected to be the basis for battery electric vehicles (BEVs), hybrid electric vehicles (HEVs) and plug-in hybrid electric vehicles (PHEVs) for the 21st century. In view of the large incremental demand for lithium that will result from expanded use of various types of EVs, long-term estimates of lithium demand and supply are advisable. For GDP growth rates of 2 to 3% and battery recycling rates of 90 to 100%, total demand for lithium for all markets is expected to be a maximum of 19.6 million tonnes through 2100. This includes 3.2 million tonnes for industrial compounds, 3.6 million tonnes for consumer electronics, and 12.8 million tonnes for EVs. Lithium-bearing mineral deposits that might supply this demand contain an estimated resource of approximately 39 million tonnes, although many of these deposits have not been adequately evaluated. These lithium-bearing mineral deposits are of two main types, non-marine playa-brine deposits and igneous deposits. Playa-brine deposits have the greatest immediate resource potential (estimated at 66% of global resources) and include the Salar de Atacama (Chile), the source of almost half of current world lithium production, as well as Zabuye (China/Tibet) and Hombre Muerto (Argentina). Additional important playa-brine lithium resources include Rincon (Argentina), Qaidam (China), Silver Peak (USA) and Uyuni (Bolivia), which together account for about 35% of the estimated global lithium resource. Information on the size and continuity of brine-bearing aquifers in many of these deposits is limited, and differences in chemical composition of brines from deposit to deposit require different extraction processes and yield different product mixes of lithium, boron, potassium and other elements. Numerous other brines in playas

Full Text Available Human resources are the primary factor for development of competitiveness and innovation and reaching competitive advantage and they try to improve corporate capabilities through various characteristics such as value creation, scarcity and difficulty of imitation. This paper investigates the effect of human resource flexibility and its dimensions on human resource development and its dimensions. The survey was conducted using descriptive-correlation method that intended to describe how human resource flexibility was effective on human resource development. Questionnaire was tool of data collection. The statistical population included one hundred employees of the Electric Company in Ilam province, thus census method was used. Reliability of the questionnaire was measured via Cronbach's alpha equal to 0.96. The findings revealed that flexibility and its dimensions were effective on human resource development and dimensions of it. As a result, human resource flexibility should be considered for development of human resources and employees with the highest flexibility should be selected.

Successful delivery of the United Nations sustainable development goals and implementation of the Paris Agreement requires technologies that utilize a wide range of minerals in vast quantities. Metal recycling and technological change will contribute to sustaining supply, but mining must continue and grow for the foreseeable future to ensure that such minerals remain available to industry. New links are needed between existing institutional frameworks to oversee responsible sourcing of minerals, trajectories for mineral exploration, environmental practices, and consumer awareness of the effects of consumption. Here we present, through analysis of a comprehensive set of data and demand forecasts, an interdisciplinary perspective on how best to ensure ecologically viable continuity of global mineral supply over the coming decades.

Assessment of in-place oil shale resources of the Eocene Green River Formation, a foundation for calculating recoverable resources

2011-01-01

The recently completed assessment of in-place resources of the Eocene Green River Formation in the Piceance Basin, Colorado; the Uinta Basin, Utah and Colorado; and the Greater Green River Basin Wyoming, Colorado, and Utah and their accompanying ArcGIS projects will form the foundation for estimating technically-recoverable resources in those areas. Different estimates will be made for each of the various above-ground and in-situ recovery methodologies currently being developed. Information required for these estimates include but are not limited to (1) estimates of the amount of oil shale that exceeds various grades, (2) overburden calculations, (3) a better understanding of oil shale saline facies, and (4) a better understanding of the distribution of various oil shale mineral facies. Estimates for the first two are on-going, and some have been published. The present extent of the saline facies in all three basins is fairly well understood, however, their original extent prior to ground water leaching has not been studied in detail. These leached intervals, which have enhanced porosity and permeability due to vugs and fractures and contain significant ground water resources, are being studied from available core descriptions. A database of all available xray mineralogy data for the oil shale interval is being constructed to better determine the extents of the various mineral facies. Once these studies are finished, the amount of oil shale with various mineralogical and physical properties will be determined.

Water is essential for life and ecological sustenance; its availability is essential component of national welfare and productivity.The country's socio-economic activities are largely dependent on the natural endowment of water resources. Kenya's water resources comprises of surface waters (rivers, lakes and wetlands) and ground water. Surface water forms 86% of total water resources while the rest is ground water Geological, topographical and climatic factors influence the natural availability and distribution of water with the rainfall distribution having the major influence. Water resources in Kenya are continuously under threat of depletion and quality degradation owing to rising population, industrialization, changing land use and settlement activities as well as natural changes. However, the anticipated climate change is likely to exacerbate the situation resulting in increased conflict over water use rights in particular, and, natural resource utilisation in general. The impacts of climate change on the water resources would lead to other impacts on environmental and socio-economic systems

Resource power and resource security: the politics of nonfuel minerals trade

International Nuclear Information System (INIS)

Kahn, O.E.

1985-01-01

The developed producers, Canada, Australia, and South Africa, and not the developing producers, are the power wielders and major tracers in nonfuel minerals. Specific circumstances allow producers to obtain compliant behavior from consumers. These include: exporter's market share, importer's degree of dependence, the material's being critical to importer's economy, and the trading system's condoning nonmarket goals. These (and other) criteria comprise an analytical device, the strategic trading relationship, which is used to demonstrate developed producer commodity power and developed consumer vulnerability. Consuming country governments rely on the private sector to deal with national enmeshment in strategic trading relationships. Japan excepted, OECD members fail either to address their continued access to nonfuel minerals, or their ability to survive supply disruption with minimum dislocation. Producer power is exemplified by Canada's threat and use of embargo to make her uranium customers tighten their nonproliferation policies. Structural power deters South Africa's ability to head off wholehearted economic pressure is the classic case

Some uranium occurrences have been discovered as mineralized outcrops and soils at Jumbang II sector. The aim of this investigation is to find the mineralization characteristic, geometric and distribution and resources estimation. The investigation method is systematic topographic, geologic, and radiometric mapping and identification of uranium on the geological aspect. At Jumbang II have been identified four mineralization zones within total area 8.56 hectare. The mineralization zones consist of quartzite rock associations. The quartzite is characterized by the existence of some mineralized veins. The veins contain uraninite and secondary uranium mineral autunite and gummite, and it also contains monazite, tourmaline, biotite, feldspar, quartz, zircon, and some ore minerals. The ore minerals consist of molybdenite, pyrrhotite, magnetite, pyrite, hematite, chalcopyrite, galena, sphalerite and arsenopyrite. Uranium content of quartzite is about 28 ppm to 18,500 ppm U (A zone), 1,125.9 ppm U (B zone) and 515 ppm U (C and D zone). The lateral and vertical ore distributions are locally. The mineralization is veins type and is controlled by intersection WNW-ESE, NNE-EEW structure direction, which was vertical to sub vertical fractures. Resources potential within 80-m depth is 3,106.893 tons U metal

THE BALNEARY RESOURCE, A GENERATOR OF BUILT HERITAGE. THE STRATIGRAPHIC FEATURES OF HERCULANE BATHS

2012-03-01

Full Text Available The balneary resource, a generator of built heritage. The stratigraphic features of Herculane Baths. The exploitation of natural resources, regardless of type, usually consists of two phases: firstly, the development of exploitation processes and secondly the development of exploitation structures – elements or built structures intended for the processing of the concerned natural resources. Many such structures have been declared architectural heritage monuments due to their historical, documentary, representative and aesthetical value, examples being numerous and varied. Water is the main resource that dictates the occurrence and development of human settlements and creates various typologies that derive from the accessibility, exploitation methods, and adaptation to the conditions and characteristics of the resource. With a peculiar evolution in terms of the dynamics of the binomial composed of natural resource and architectural heritage resource, mineral resources (especially balneal waters fall in a distinct category: although mainly utilitarian in function, they have also cultural, aesthetic and even religious purposes. Besides their curative properties, spa mineral waters can be used as is, in many cases directly from the source, this being the explanation why they have generated such great and continuous interest - forming today a highly stratified built heritage background. Keeping in mind the sustainable development for a medium or a long period of time, an analysis of the interrelations between the balneal natural resource and the deriving architectural heritage is necessary. The purpose of such analysis is determining the limitations of exploitation and identifying the optimal means of safeguarding both elements, the natural water resource and the anthropogenic one, for a more rational territory management.

Should Canada Worry About a Resource Curse?

Directory of Open Access Journals (Sweden)

Alan Gelb

2014-01-01

Full Text Available An abundance of natural resources might seem like something any nation would want to be blessed with. But in some countries, a bounty of energy, minerals and other resources can become as much a curse as a blessing. The difference between whether resources benefit a country’s people, or lead to adversity and even suffering, has everything to do with how a country manages its resources. It is the difference between a resource-rich, free and democratically accountable country, such as Canada, and a resourcerich, corrupt, violent and impoverished country, such as the Democratic Republic of Congo. In many resource-rich countries, the effect of ample natural wealth has been to sever the accountability link between citizens and government, slowing or even reversing democratic and social progress, while mostly enriching a few politically favoured constituencies. Canada’s plentiful resources are an indisputable blessing, and those critics of federal industrial policy who compare this country to illiberal and corrupt “petro-states” are being either ignorant or deceitful. There are numerous critical factors at work here that ensure that the Canadian public benefits, rather than suffers, from our natural endowments. We have a diversity of resources, as opposed to being reliant on a single commodity, and our natural-resource sector makes up only a small portion of our larger economy. We have well-established and diligently enforced standards for financial transparency and accountability, in both the private and public sectors. But, just as importantly, there is a national consensus in Canada that public wealth amassed from resource rents should be invested in strengthening human capital, through education, training and social services, as well as in improved infrastructure and better governance, eventually parlaying natural-resource wealth into a yet larger, further-diversified economy. But Canada — and especially resource-rich provinces, such as

The CSIRO Mineral Resources Flagship was established to tackle medium- to long-term challenges facing the Australian mineral industry across the value chain from exploration and mining through mineral processing within the framework of an economically, environmentally and socially sustainable minerals industry. This broad portfolio demands collaboration and data exchange with a broad range of participants and data providers across government, research and industry. It is an ideal environment to link geoscience informatics platforms to application across the resource extraction industry and to unlock the value of data integration between traditionally discrete parts of the minerals digital value chain. Despite the potential benefits, data integration remains an elusive goal within research and industry. Many projects use only a subset of available data types in an integrated manner, often maintaining the traditional discipline-based data 'silos'. Integrating data across the entire minerals digital value chain is an expensive proposition involving multiple disciplines and, significantly, multiple data sources both internal and external to any single organisation. Differing vocabularies and data formats, along with access regimes to appropriate analysis software and equipment all hamper the sharing and exchange of information. AuScope has addressed the challenge of data exchange across organisations nationally, and established a national geosciences information infrastructure using open standards-based web services. Federated across a wide variety of organisations, the resulting infrastructure contains a wide variety of live and updated data types. The community data standards and infrastructure platforms that underpin AuScope provide important new datasets and multi-agency links independent of software and hardware differences. AuScope has thus created an infrastructure, a platform of technologies and the opportunity for new ways of working with and integrating

The Antarctic Offshore Stratigraphy project (ANTOSTRAT; 1989–2002) was an extremely successful collaboration in international marine geological science that also lifted the perceived “veil of secrecy” from studies of potential exploitation of Antarctic marine mineral resources. The project laid the groundwork for circum-Antarctic seismic, drilling, and rock coring programs designed to decipher Antarctica’s tectonic, stratigraphic, and climate histories. In 2002, ANTOSTRAT evolved into the equally successful and currently active Antarctic Climate Evolution research program. The need for, and evolution of, ANTOSTRAT was based on two simple tenets within SCAR and the Antarctic Treaty: international science collaboration and open access to data. The ANTOSTRAT project may be a helpful analog for other regions of strong international science and geopolitical interests, such as the Arctic. This is the ANTOSTRAT story.

Potential release scenario and radiological consequence evaluation of mineral resources at WIPP

International Nuclear Information System (INIS)

Little, M.S.

1982-05-01

This report has reviewed certain of the natural resources which may be found at the site of the nuclear waste repository being considered for southeastern New Mexico, and discussed the scenarios which have been used to estimate the radiological consequences from the mining of these resources several hundred years after the radioactive waste has been emplaced. It has been concluded that the radiological consequences of the mining of potash or hydrocarbons (mostly natural gas) are probably bounded by the consequences of hydrologic breach scenarios already considered by the US Department of Energy, and by reports of EEG. These studies conclude that the resultant doses would not constitute a significant threat to public health. This report also evaluates the radiological consequences of solution mining of halite at the WIPP site. Although such mining in the Delaware Basin and particularly at the WIPP site, is not likely at the present time, significant economic, social or climatic changes a few hundred years after emplacement may make these resources more attractive. The DOE did not consider such mining at the site credible

Undiscovered resource evaluation: Towards applying a systematic approach to uranium

International Nuclear Information System (INIS)

Fairclough, M.; Katona, L.

2014-01-01

Evaluations of potential mineral resource supply range from spatial to aspatial, and everything in between across a range of scales. They also range from qualitative to quantitative with similar hybrid examples across the spectrum. These can compromise detailed deposit-specific reserve and resource calculations, target generative processes and estimates of potential endowments in a broad geographic or geological area. All are estimates until the ore has been discovered and extracted. Contemporary national or provincial scale evaluations of mineral potential are relatively advanced and some include uranium, such as those for South Australia undertaken by the State Geological Survey. These play an important role in land-use planning as well as attracting exploration investment and range from datato knowledge-driven approaches. Studies have been undertaken for the Mt Painter region, as well as for adjacent basins. The process of estimating large-scale potential mineral endowments is critical for national and international planning purposes but is a relatively recent and less common undertaking. In many cases, except at a general level, the data and knowledge for a relatively immature terrain is lacking, requiring assessment by analogy with other areas. Commencing in the 1980s, the United States Geological Survey, and subsequently the Geological Survey of Canada evaluated a range of commodities ranging from copper to hydrocarbons with a view to security of supply. They developed innovative approaches to, as far as practical, reduce the uncertainty and maximise the reproducibility of the calculations in information-poor regions. Yet the approach to uranium was relatively ad hoc and incomplete (such as the US Department of Energy NURE project). Other historic attempts, such as the IAEA-NEA International Uranium Resource Evaluation Project (IUREP) in the 1970s, were mainly qualitative. While there is still no systematic global evaluation of undiscovered uranium resources

1st International Ocean Technology Congress on EEZ Resources : Technology Assessment

CERN Document Server

Champ, Michael

1990-01-01

Today western nations consume annually only a small percentage of their resources from the sea, despite the proclamation of Exclusive Economic Zones (EEZ) by many. In contrast, most Pacific Basin Countries obtain more than a quarter of their annual needs from the ocean. Determination of greater rewards from the development of marine resources is markedly inhibited by the limited technical abilities available to locate and assess them. Knowledge of Exclusive Economic Zone resources is schematic and generalised, and a detailed understanding of the geology and processes relating to the economic use of the seafloor is both fragmentary and very basic. Technology for mapping the mineral resources of continental shelves and ocean areas, except in active offshore hydrocarbon provinces, has been largely developed in pursuit of scientific objectives and competence to rapidly appraise economic potential is limited. Similarly, the capability to characterise and evaluate the other resources of the seas is rudimentary. The...

EVALUATION OF SUBSOIL RESOURCES, LAND RESOURCES AND SOILS IN THE COURSE OF ENGINEERING AND ECOLOGICAL SURVEYS AT THE DESIGN STAGE OF CONSTRUCTION PROJECTS

Platov Nikolaj Aleksandrovich

2012-10-01

Full Text Available Effective environmental legislative acts, industrial regulations and Construction Standards and Norms do not comprise a consistent system governing rational use of natural resources. Inconsistency of regulatory acts, unavailability of a single approach or a methodological background backing the development of new and the update of effective regulatory documents causes inconsistency of engineering and ecological information. The inconsistency prevents any competent application and correlation of the information about the condition and properties of the ground and soils. The main objective of an engineering survey is the supply of trustworthy information to teams of designers. The quality of the engineering and ecological information stands behind the safety of buildings and structures. The quality of any environment-related information and data concerning any environmental protection measures is consequent to the quality of regulatory documents. In addition to their role in the built environment, resources of the lithosphere serve as the basis for the development of almost all branches of industry and other types of human activities. Effective legal and regulatory documents ignore the fact that subsoil resources serve as the material and physical basis of the living environment on Earth. Foundations of the Legislation of the USSR and the Union Republics on Subsoil Resources served as the basis for their protection. The successor legislation includes in excess of 40 regulatory documents that govern the extraction of natural resources and losses that accompany the exploitation of their deposits. The principal acts include the Unified Rules Governing Protection of Subsoil Resources in the course of Development of Deposits of Solid Mineral Resources (1985 and other acts approved by the Principal State Technical Supervision Committee; the above Unified Rules have not undergone any substantial changes since the days of the USSR.

Unlocking the Treasures of the Ocean: Current Assessment and Future Perspectives of Seafloor Resources (C.F Gauss Lecture)

Science.gov (United States)

Jegen, Marion

2016-04-01

Oceans cover 70% of the Earth's surface, and there is reason to believe that the wealth of mineral and carbon resources on the seafloor is similar to deposits on land. While off-shore energy resources such as oil and gas are nowadays regarded as conventional, energy resources in form of methane hydrates and seafloor mineral deposits are yet unconventional and at best marginally economic. However, taking into account global population growth, geopolitics and technological development (both in terms of increasing industrialization and possibility to explore and mine seafloor resources), these resources might play a more fundamental role in the future. Resource assessment and understanding of the geological formation process of resources are topics in marine geosciences with broad relevance to society. The lecture presents an overview of the geophysical exploration of the seafloor and its resource potential. Starting from the link of physical parameter anomalies associated with resources, I will explore marine technological developments on how to sense them remotely from the seafloor. Also the question will be addressed of how well we can actually quantify the amount of resources from geophysical data. The process will be illustrated based on theoretical work as well as case studies from around the world.

Mineralized environments in the Dillon, Butte, Hamilton, and Elk City 1 0 x 2 0 NTMS Quadrangles were identified and characterized from the National Uranium Resource Evaluation (NURE) Hydrogeochemical and Stream Sediment Reconnaissance and Aerial Radiometric and Magnetic Survey data, folio data, and other data sets used in this study. Methods applied to reconnaissance for uranium during the NURE program were used successfully in this project to recognize and delineate locales that have mineral-resource potential. These methods included preparation and interpretation of maps of geochemical, aerial radiometric, and aeromagentic data, as well as interpretation of univariate and multivariate statistical analyses of NURE data sets. Data interpretations were conducted by a contingency approach that puts a variety of statistical and cartographic tools at the disposal of the geologist. These tools were applied selectively to the data until the geochemical and geophysical signature of an anomalous locale was described and characterized to the geologist's satisfaction. Ten areas known to be mineralized were described as type localities and used to calibrate the geochemical and geophysical models employed in the study. Other areas exhibiting anomalous geochemical and (or) geophysical characteristics were analogized to the type localities. Thirty anomalous areas were delineated during this study; 17 of the 30 are believed to warrant further investigation. Three locales contain Tertiary intrusive bodies that were delineated on the basis of their characteristic signatures and trace-element contents. 5 figures, 10 tables

Natural resources as a factor of economic growth in Kosovo

Directory of Open Access Journals (Sweden)

Haki Shatri

2015-11-01

Full Text Available In the history of the economic growth, there are numerous examples of countries that have developed based on their available natural resources. Especially, these assets have been the propulsion of the development in the initial period. But we also find some cases where countries with limited natural resources have experienced dynamic economic development. Kosovo is the last federal unit dismembered from former Yugoslavia after a decade under Milosevic’s Serbian regime and a two years’ war. International intervention and the inclusion of the country under an international protectorate created the conditions for the development of devastated economy by war and the robbery to be recovered together with the creation of institutional and economic infrastructure (Lidhja e Ekonomistëve të Kosovës, 1996. Under these conditions, everything had to start from scratch. The only development factor that Kosovo possessed was the human factor - age structure and the abundant natural resources, especially in key sectors such as the energy and in mining and minerals, agriculture and tourism. Thus it is sustainable the conclusion that “The rapid and sustainable economic and social development of Kosovo depends substantially from the implementation of the appropriate policies and suitable economic reforms that enable more rational use of its natural and human resources”. The list of the available resources of Kosovo is long. Kosovo possesses significant amount of all mineral raw materials in both quality and quantity terms. Among the most important raw materials have been ranked the power-lignite mining that is stretched into three basins and it is estimated to be around 9 billion exploitable tons (Kelmendi, 2012. Kosovo also owns mineral resources which are found in the Trepca’s Metals basin. The geological researches show favorable conditions of exploitation and high quality of the ore. Mainly one can found the lead, zinc, silver and other

Exploitation of Natural Resources and the Public Sector in Greenland

Nielsen, Søren Bo

This paper considers the role of the public sector in future exploitation of non-renewable resources, especially minerals, in Greenland. The focus is on fiscal sustainability, principles for public sector involvement and the form of government take from mining activities. At present, the public...... budget in Greenland is nearly in balance, but at unchanged policies and standards public expenditures relative to GDP are bound to increase dramatically over the next decades due to population ageing. At the same time, the freezing of the block grant from Denmark implies a decrease in revenues relative...... to GDP. Hence, fiscal policy is quite far from being sustainable. Apart from a need for reforms, these facts also constrain the possible role of the public sector in future resource exploitation. In any case, the government should preferably adhere to strict principles when developing the mineral sector...

Recent revisions of phosphate rock reserves and resources: a critique

Science.gov (United States)

Edixhoven, J. D.; Gupta, J.; Savenije, H. H. G.

2014-12-01

Phosphate rock (PR) is a finite mineral indispensable for fertilizer production, while P (phosphorus) is a major pollutant if applied or discharged in excess, causing widespread eutrophication (Carpenter and Bennet, 2011). High-grade PR is obtained from deposits which took millions of years to form and which are gradually being depleted. Recently, global PR reserves as reported by the US Geological Survey (USGS) have increased from 16 000 Mt PR in 2010 to 65 000 Mt PR in 2011 and further to 67 000 Mt PR in 2014. The majority of this 4-fold increase is based on a 2010 report by the International Fertilizer Development Center (IFDC), which increased Moroccan reserves from 5700 Mt PR as reported by USGS, to 51 000 Mt PR, reported as upgraded ("beneficiated") concentrate. The report also increased global resources from 163 000 Mt PR reported in the literature in 1989 to 290 000 Mt PR. IFDC used a simplified resource terminology which does not use the underlying thresholds for reserves and resources used in the USGS classification. IFDC proposed that agreement should be reached on PR resource terminology which should be as simple as possible. The report has profoundly influenced the PR scarcity debate, shifting the emphasis from resource scarcity to the pollution angle of the phosphate problem. In view of the high dependence of food production on PR and the importance of data on PR reserves and resources for scientific analysis and policy making, data on PR deposits should be transparent, comparable, reliable, and credible. We analyze (i) how IFDC's simplified terminology compares to international best practice in resource classification and whether it is likely to yield data that meet these requirements, (ii) whether the difference in volume between raw PR ore and upgraded PR concentrate is sufficiently noted in the literature, and (iii) whether the IFDC report presents an accurate picture of PR reserves and resources. We conclude that, while there is a global

A review of the surface features and properties, surfactant adsorption and floatability of four key minerals of diasporic bauxite resources.

Science.gov (United States)

Zhang, Ningning; Nguyen, Anh V; Zhou, Changchun

Diasporic bauxite represents one of the major aluminum resources. Its upgrading for further processing involves a separation of diaspore (the valuable mineral) from aluminosilicates (the gangue minerals) such as kaolinite, illite, and pyrophyllite. Flotation is one of the most effective ways to realize the upgrading. Since flotation is a physicochemical process based on the difference in the surface hydrophobicity of different components, determining the adsorption characteristics of various flotation surfactants on the mineral surfaces is critical. The surfactant adsorption properties of the minerals, in turn, are controlled by the surface chemistry of the minerals, while the latter is related to the mineral crystal structures. In this paper, we first discuss the crystal structures of the four key minerals of diaspore, kaolinite, illite, and pyrophyllite as well as the broken bonds on their exposed surfaces after grinding. Next, we summarize the surface chemistry properties such as surface wettability and surface electrical properties of the four minerals, and the differences in these properties are explained from the perspective of mineral crystal structures. Then we review the adsorption mechanism and adsorption characteristics of surfactants such as collectors (cationic, anionic, and mixed surfactants), depressants (inorganic and organic), dispersants, and flocculants on these mineral surfaces. The separation of diaspore and aluminosilicates by direct flotation and reverse flotation are reviewed, and the collecting properties of different types of collectors are compared. Furthermore, the abnormal behavior of the cationic flotation of kaolinite is also explained in this section. This review provides a strong theoretical support for the optimization of the upgrading of diaspore bauxite ore by flotation and the early industrialization of the reverse flotation process.

Space Resource Utilization: Technologies and Potential Synergism with Terrestrial Mining

Science.gov (United States)

Sanders, Gerald B.

2015-01-01

Space Resources and Their Uses: The idea of using resources in space to support human exploration and settlement or for economic development and profit beyond the surface of Earth has been proposed and discussed for decades. Work on developing a method to extract oxygen from lunar regolith started even before humans set foot on the Moon for the first time. The use of space resources, commonly referred to as In Situ Resource Utilization (ISRU), involves the processes and operations to harness and utilize resources in space (both natural and discarded) to create products for subsequent use. Potential space resources include water, solar wind implanted volatiles (hydrogen, helium, carbon, nitrogen, etc.), vast quantities of metals and minerals in extraterrestrial soils, atmospheric constituents, unlimited solar energy, regions of permanent light and darkness, the vacuum and zero-gravity of space itself, trash and waste from human crew activities, and discarded hardware that has completed its primary purpose. ISRU covers a wide variety of concepts, technical disciplines, technologies, and processes. When considering all aspects of ISRU, there are 5 main areas that are relevant to human space exploration and the commercialization of space: 1. Resource Characterization and Mapping, 2. In Situ Consumables Production, 3. Civil Engineering and Construction, 4. In Situ Energy Production and Storage, and 5. In Situ Manufacturing.

Update estimated uraniumn resources are 11,800 tU at costs less than 130 U$S/kgU to produce. The demand of the operation, building and projected nuclear power plants will be of approximately 10,000 tU before the year 2000. This equilibrium shows the need of developing rapidly new resources because of an increasingly participation of the nuclear energy. The evolution of exploration and the critical needs of developing activities related to it, are briefly explaned. The exploration cost is 8.9 U$S/kgU what is considered acceptable in relation to international experience. Also, some concepts that should be included in the legislation on nuclear minerals are proposed. (Author) [es

How to spend it: Resource wealth and the distribution of resource rents

International Nuclear Information System (INIS)

Segal, Paul

2012-01-01

Natural resource revenues differ from other government revenues both in their time profile, and in their political and legal status: they are volatile and exhaustible, and belong to all citizens of the country in which they are located. This paper discusses the theory of natural resource revenues and examines expenditure practices in a range of resource-rich countries. It considers both the distributional impact and the efficiency of expenditure policies, focusing on the extent to which they succeed in providing all citizens with their share of the benefits due to natural resources. - Highlights: ► We examine the relationship between resource rents and government resource revenues. ► We discuss the intertemporal management of resource revenues in theory and in practice. ► We critically examine existing policies for distributing resource revenues to populations.

Frontier In-Situ Resource Utilization for Enabling Sustained Human Presence on Mars

Science.gov (United States)

Moses, Robert W.; Bushnell, Dennis M.

2016-01-01

The currently known resources on Mars are massive, including extensive quantities of water and carbon dioxide and therefore carbon, hydrogen and oxygen for life support, fuels and plastics and much else. The regolith is replete with all manner of minerals. In Situ Resource Utilization (ISRU) applicable frontier technologies include robotics, machine intelligence, nanotechnology, synthetic biology, 3-D printing/additive manufacturing and autonomy. These technologies combined with the vast natural resources should enable serious, pre- and post-human arrival ISRU to greatly increase reliability and safety and reduce cost for human colonization of Mars. Various system-level transportation concepts employing Mars produced fuel would enable Mars resources to evolve into a primary center of trade for the inner solar system for eventually nearly everything required for space faring and colonization. Mars resources and their exploitation via extensive ISRU are the key to a viable, safe and affordable, human presence beyond Earth. The purpose of this paper is four-fold: 1) to highlight the latest discoveries of water, minerals, and other materials on Mars that reshape our thinking about the value and capabilities of Mars ISRU; 2) to summarize the previous literature on Mars ISRU processes, equipment, and approaches; 3) to point to frontier ISRU technologies and approaches that can lead to safe and affordable human missions to Mars; and 4) to suggest an implementation strategy whereby the ISRU elements are phased into the mission campaign over time to enable a sustainable and increasing human presence on Mars.

The Analysis of Pricing Power of Preponderant Metal Mineral Resources under the Perspective of Intergenerational Equity and Social Preferences: An Analytical Framework Based on Cournot Equilibrium Model

Directory of Open Access Journals (Sweden)

Meirui Zhong

2014-01-01

Full Text Available This paper combines intergenerational equity equilibrium and social preferences equilibrium with Cournot equilibrium solving the technological problem of intergenerational equity and strategic value compensation confirmation, achieving the effective combination between sustainable development concept and value evaluation, thinking and expanding the theoretical framework for the lack of pricing power of mineral resources. The conclusion of the theoretical model and the numerical simulation shows that intergenerational equity equilibrium and social preferences equilibrium enhance international trade market power of preponderant metal mineral resources owing to the production of intergenerational equity compensation value and strategic value. However, the impact exerted on Cournot market power by social preferences is inconsistent: that is, changes of altruistic Cournot equilibrium and reciprocal inequity Cournot equilibrium are consistent, while inequity aversion Cournot equilibrium has the characteristic of loss aversion, namely, under the consideration of inequity aversion Cournot competition, Counot-Nash equilibrium transforms monotonically with sympathy and jealousy of inequity aversion.

This paper reports on the Desolation Canyon, Turtle Canyon, and Floy Canyon Wilderness Study Areas which include 242,000 acres, 33,690 acres, and 23,140 acres. Coal deposits underlie all three study areas. Coal zones in the Blackhawk and Nelsen formations have identified bituminous coal resources of 22 million short tons in the Desolation Canyon Study Area, 6.3 million short tons in the Turtle Canyon Study Area, and 45 million short tons in the Floy Canyon Study Area. In-place inferred oil shale resources are estimated to contain 60 million barrels in the northern part of the Desolation Canyon area. Minor occurrences of uranium have been found in the southeastern part of the Desolation Canyon area and in the western part of the Floy Canyon area. Mineral resource potential for the study areas is estimated to be for coal, high for all areas, for oil and gas, high for the northern tract of the Desolation Canyon area and moderate for all other tracts, for bituminous sandstone, high for the northern part of the Desolation Canyon area, and low for all other tracts, for oil shale, low in all areas, for uranium, moderate for the Floy Canyon area and the southeastern part of the Desolation Canyon area and low for the remainder of the areas, for metals other than uranium, bentonite, zeolites, and geothermal energy, low in all areas, and for coal-bed methane unknown in all three areas

Competition over personal resources favors contribution to shared resources in human groups.

Directory of Open Access Journals (Sweden)

Jessica L Barker

Full Text Available Members of social groups face a trade-off between investing selfish effort for themselves and investing cooperative effort to produce a shared group resource. Many group resources are shared equitably: they may be intrinsically non-excludable public goods, such as vigilance against predators, or so large that there is little cost to sharing, such as cooperatively hunted big game. However, group members' personal resources, such as food hunted individually, may be monopolizable. In such cases, an individual may benefit by investing effort in taking others' personal resources, and in defending one's own resources against others. We use a game theoretic "tug-of-war" model to predict that when such competition over personal resources is possible, players will contribute more towards a group resource, and also obtain higher payoffs from doing so. We test and find support for these predictions in two laboratory economic games with humans, comparing people's investment decisions in games with and without the options to compete over personal resources or invest in a group resource. Our results help explain why people cooperatively contribute to group resources, suggest how a tragedy of the commons may be avoided, and highlight unifying features in the evolution of cooperation and competition in human and non-human societies.

Magnesium is the eighthmost abundant element in Earth’s crust, and the second-most abundant metal ion in seawater. Although magnesium is found in more than 60 minerals, only brucite, dolomite, magnesite and carnallite are commercially important for their magnesium content. Magnesium and its compounds also are recovered from seawater, brines found in lakes and wells, and bitterns (salts).

The author follows the trace of man and his relationships to mineral resources through the cultural history known: From the first evidence of working and use of rock by man, over copper and iron, then gold and silver, to zinc and lead. The book points out how all sectors of human life received important stimuli from mineral resources. It encompasses a huge section of history, reaching from Mesopotamia as the cradle of culture to the historically relevant events in the central European countries, and describing primitive mining in Anatolia between 8000 and 5000 B.C. as well as the extraction of minerals and their processing in the 20th century. Thus the reader comes to know astonishing facts and details relating to the working conditions for instance of Egyptian and Greek slaves, the mines of Solomon, the first strike in antiquity, the art and social position of smiths since antiquity, and the economic situation of miners and foundry workers. The chapter on medieval mining is restricted to individual aspects of mining in Germany. Mining in modern times is only marginally deals with. The scientific results of the last 20 years are not taken into account. (MOS).

Exploitation of natural resources and conflict in Colombia

Directory of Open Access Journals (Sweden)

Luis Eduardo Sandoval

2017-11-01

Full Text Available Colombia has increasingly been specializing in the extraction of mineral and energy resources such as gold, coal, oil and ferronickel. These activities, in the context of state weakness, have engendered conflicts of different dimensions. This paper proposes an indicator of conflict related to mineral exploitation that classifies five dimensions of conflict: social, economic, cultural, political and environmental. The aggregate indicator shows that murders, displacement of Afrodescendent populations, flooding, pollution, fires, infant mortality, coca crops and sexual offenses are highly and positively correlated with the number of conflicts.

Energy Resource Planning. Optimal utilization of energy resources

International Nuclear Information System (INIS)

Miclescu, T.; Domschke, W.; Bazacliu, G.; Dumbrava, V.

1996-01-01

For a thermal power plants system, the primary energy resources cost constitutes a significant percentage of the total system operational cost. Therefore a small percentage saving in primary energy resource allocation cost for a long term, often turns out to be a significant monetary value. In recent years, with a rapidly changing fuel supply situation, including the impact of energy policies changing, this area has become extremely sensitive. Natural gas availability has been restricted in many areas, coal production and transportation cost have risen while productivity has decreased, oil imports have increased and refinery capacity failed to meet demand. The paper presents a mathematical model and a practical procedure to solve the primary energy resource allocation. The objectives is to minimise the total energy cost over the planning period subject to constraints with regards to primary energy resource, transportation and energy consumption. Various aspects of the proposed approach are discussed, and its application to a power system is illustrated.(author) 2 figs., 1 tab., 3 refs

1995-01-01

The Republic of Macedonia is situated in the central part of the Balcan Peninsula and covers a surface of 25. 713 km 2 Its territory is found in one of the most significant geothermal zones in this part of Balkans. The earths crust in this region suffers poli phase structural deformations, which as a result gives different structural features. The geothermal explorations in the Republic of Macedonia intensively started to conduct after 1970, after the first effects of the energy crisis. As a result of these explorations, more than 50 springs of mineral and thermo mineral waters with a total yield of more than 1.400 I./sec. And proved exploitation reservoirs of more than 1.000 I./sec. with temperatures higher than the medium year seasons hesitations for this part of the Earth in the boundaries of 20-75 o C with significant quantities of geothermal energy. This paper will shortly present the available geothermal resources and classification, according the type of geothermal energy, hydro geothermal, lithogeothermal and according the way of transport of the geothermal energy, convective and conductive systems. The next will present short descriptions of the resources, the degree of exploitation and the prognosis dimensions of the reservoirs. (Original)

The U.S. Geological Survey (USGS) collaborated with the China Geological Survey (CGS) to conduct a mineral resource assessment of Mesozoic porphyry copper deposits in East Asia. This area hosts several very large porphyry deposits, exemplified by the Dexing deposit in eastern China that contains more than 8,000,000 metric tons of copper. In addition, large parts of the area are undergoing active exploration and are likely to contain undiscovered porphyry copper deposits.

Low-rank coal study : national needs for resource development. Volume 2. Resource characterization

Energy Technology Data Exchange (ETDEWEB)

1980-11-01

Comprehensive data are presented on the quantity, quality, and distribution of low-rank coal (subbituminous and lignite) deposits in the United States. The major lignite-bearing areas are the Fort Union Region and the Gulf Lignite Region, with the predominant strippable reserves being in the states of North Dakota, Montana, and Texas. The largest subbituminous coal deposits are in the Powder River Region of Montana and Wyoming, The San Juan Basin of New Mexico, and in Northern Alaska. For each of the low-rank coal-bearing regions, descriptions are provided of the geology; strippable reserves; active and planned mines; classification of identified resources by depth, seam thickness, sulfur content, and ash content; overburden characteristics; aquifers; and coal properties and characteristics. Low-rank coals are distinguished from bituminous coals by unique chemical and physical properties that affect their behavior in extraction, utilization, or conversion processes. The most characteristic properties of the organic fraction of low-rank coals are the high inherent moisture and oxygen contents, and the correspondingly low heating value. Mineral matter (ash) contents and compositions of all coals are highly variable; however, low-rank coals tend to have a higher proportion of the alkali components CaO, MgO, and Na/sub 2/O. About 90% of the reserve base of US low-rank coal has less than one percent sulfur. Water resources in the major low-rank coal-bearing regions tend to have highly seasonal availabilities. Some areas appear to have ample water resources to support major new coal projects; in other areas such as Texas, water supplies may be constraining factor on development.

In 2010, for a second year, the natural resources youth training program (NRYTP) was developed in northern Manitoba thanks to Manitoba Keewatinowi Okimakanak Inc. (MKO) and the collaboration of 42 sponsors. 16 aboriginal youth representing six northern communities took part in the five-week program located at the Egg Lake camp. The objective was to provide these resources rangers with knowledge and training in the most widespread resource sectors in northern Manitoba, including mining, forestry and hydropower. Trainers and experts provided by industry partners offered training sessions, hands-on work experience and other activities to help resource rangers to acquire a better understanding of the employability in this field in the northern region and the knowledge and skills the resource-based careers require. Life and professional skills training was given by the camp staff and local professionals. On-site elders and cultural events also allowed the integration of a northern Cree cultural component. Three staff members, a cook and elders assisted daily the resource rangers. Many improvements and refinements have been made since the success of the 2009 program, including the involvement of a larger number of communities, program contributors and program graduates. The program length has doubled and the number of jobs created has increased, important cultural aspects were introduced and the overall expenses were reduced.

Ahlbrandt, T.S.; Blystad, P.; Young, E.D.; Slavov, S.; Heiberg, S.

2003-01-01

The United Nations has developed an international framework classification for solid fuels and minerals (UNFC). This is now being extended to petroleum by building on the joint classification of the Society of Petroleum Engineers (SPE), the World Petroleum Congresses (WPC) and the American Association of Petroleum Geologists (AAPG). The UNFC is a 3-dimansional classification. This: Is necessary in order to migrate accounts of resource quantities that are developed on one or two of the axes to the common basis; Provides for more precise reporting and analysis. This is particularly useful in analyses of contingent resources. The characteristics of the SPE/WPC/AAPG classification has been preserved and enhanced to facilitate improved international and national petroleum resource management, corporate business process management and financial reporting. A UN intergovernmental committee responsible for extending the UNFC to extractive energy resources (coal, petroleum and uranium) will meet in Geneva on October 30th and 31st to review experiences gained and comments received during 2003. A recommended classification will then be delivered for consideration to the United Nations through the Committee on Sustainable Energy of the Economic Commission for Europe (UN ECE).

Geothermal resource assessment of Ouray, Colorado. Resource series 15

Energy Technology Data Exchange (ETDEWEB)

Zacharakis, T.G.; Ringrose, C.D.; Pearl, R.H.

1981-01-01

In 1979, a program was initiated to delineate the geological features controlling the occurrence of geothermal resources in Colorado. In the Ouray area, this effort consisted of geological mapping, soil mercury geochemical surveys and resistivity geophysical surveys. The soil mercury obtained inconclusive results, with the Box Canyon area indicating a few anomalous values, but these values are questionable and probably are due to the hot spring activity and mineralization within the Leadville limestone rock. One isolated locality indicating anomalous values was near the Radium Springs pool and ball park, but this appears to be related to warm waters leaking from a buried pipe or from the Uncompahgre River. The electrical resistivity survey however, indicated several areas of low resistivity zones namely above the Box Canyon area, the power station area and the Wiesbaden Motel area. From these low zones it is surmised that the springs are related to a complex fault system which serves as a conduit for the deep circulation of ground waters through the system.

Mineral, Energy, and Fertilizer Resources of the North Coast of Peru: Perspective from the Santa Rita B Archaeological Site

Science.gov (United States)

Brooks, William E.; Kent, Jonathan D.; Willett, Jason C.

2004-01-01

The Santa Rita B archaeological site is in the Chao Valley, approximately 65 km southeast of Trujillo, northern Peru. Location of Santa Rita B at the emergence of several drainages from the Andean cordillera is an important factor in the almost continuous occupation of the site over the past 3,000 years. Mineral resources are abundant throughout the Andes; however, the north coast of Peru was an important center for pre-Columbian mining, metallurgy, and craftsmanship. Success of the Chavin, Moche, Chimu, and other north coast cultures is directly related to the availability and exploitation of mineral and energy resources that include: gold (?silver), as electrum, mainly from placers, and copper from local oxide and carbonate occurrences and from sulfides related to copper porphyry occurrences in the cordillera. An alloy of these three metals is referred to as tumbaga, which is the primary material for Andean metalcraft. Anthracite was used for mirrors by north coast cultures and is available near Rio Chicama, Rio Santa, and east of Santa Rita B. These outcrops are a part of the Alto Chicama, Peru's largest coalfield, which extends from Rio Chicama, in the north, for 200 km southward to Rio Santa. Charcoal from the algorrobo tree and llama dung are considered to be the common pre-Columbian energy sources for cooking and metalwork; however, availability and the higher heat content of anthracite indicate that it was used in metallurgical applications. Bitumen is available from petroleum seeps near Talara, north of the study area, and may have been used as glue or as cement. Hematite, goethite, limonite, and manganese oxides from clay-altered volcanic rock may have provided color and material for ceramics. Guano from the Islas Gua?apes, Chinchas, and Ballestas was used as fertilizer for cotton and other crops.

Within this paper we present an autonomic Computing resources management system, used by LHCb for assessing the status of their Grid resources. Virtual Organizations Grids include heterogeneous resources. For example, LHC experiments very often use resources not provided by WLCG, and Cloud Computing resources will soon provide a non-negligible fraction of their computing power. The lack of standards and procedures across experiments and sites generated the appearance of multiple information systems, monitoring tools, ticket portals, etc... which nowadays coexist and represent a very precious source of information for running HEP experiments Computing systems as well as sites. These two facts lead to many particular solutions for a general problem: managing the experiment resources. In this paper we present how LHCb, via the DIRAC interware, addressed such issues. With a renewed Central Information Schema hosting all resources metadata and a Status System (Resource Status System) delivering real time information, the system controls the resources topology, independently of the resource types. The Resource Status System applies data mining techniques against all possible information sources available and assesses the status changes, that are then propagated to the topology description. Obviously, giving full control to such an automated system is not risk-free. Therefore, in order to minimise the probability of misbehavior, a battery of tests has been developed in order to certify the correctness of its assessments. We will demonstrate the performance and efficiency of such a system in terms of cost reduction and reliability.

The biomedical research community relies on a diverse set of resources, both within their own institutions and at other research centers. In addition, an increasing number of shared electronic resources have been developed. Without effective means to locate and query these resources, it is challenging, if not impossible, for investigators to be aware of the myriad resources available, or to effectively perform resource discovery when the need arises. In this paper, we describe the development and use of the Biomedical Resource Ontology (BRO) to enable semantic annotation and discovery of biomedical resources. We also describe the Resource Discovery System (RDS) which is a federated, inter-institutional pilot project that uses the BRO to facilitate resource discovery on the Internet. Through the RDS framework and its associated Biositemaps infrastructure, the BRO facilitates semantic search and discovery of biomedical resources, breaking down barriers and streamlining scientific research that will improve human health.

Cowart, R.; Harrington, C.; Moskovitz, D.; Shirley, W.; Weston, F.; Sedano, R.

2002-10-01

Designing and implementing credit-based pilot programs for distributed resources distribution is a low-cost, low-risk opportunity to find out how these resources can help defer or avoid costly electric power system (utility grid) distribution upgrades. This report describes implementation options for deaveraged distribution credits and distributed resource development zones. Developing workable programs implementing these policies can dramatically increase the deployment of distributed resources in ways that benefit distributed resource vendors, users, and distribution utilities. This report is one in the State Electricity Regulatory Policy and Distributed Resources series developed under contract to NREL (see Annual Technical Status Report of the Regulatory Assistance Project: September 2000-September 2001, NREL/SR-560-32733).

Duality between resource reservation and proportional share resource allocation

Science.gov (United States)

Stoica, Ion; Abdel-Wahab, Hussein; Jeffay, Kevin

1997-01-01

We describe anew framework for resource allocation that unifies the well-known proportional share and resource reservation policies. Each client is characterized by two parameters: a weight that represents the rate at which the client 'pays' for the resource, and a share that represents the fraction of the resource that the client should receive. A fixed rate corresponds to a proportional share allocation, while a fixed share corresponds to a reservation. Furthermore, rates and shares are duals of each other. Once one parameters is fixed the other becomes fixed as well. If a client asks for a fixed share then the level of competition for the resource determines the rate at which it has to pay, while if the rate is fixed, level of competition determines the service time the clients should receive. To implement this framework we use a new proportional share algorithm, called earliest eligible virtual deadline first, that achieves optical accuracy in the rates at which process execute. This makes it possible to provide support for highly predictable, real-time services. As a proof of concept we have implemented a prototype of a CPU scheduler under the FreeBSD operating system. The experimental results show that our scheduler achieves the goal of providing integrated support for batch and real-time applications.

The UNFC-2009 applies to fossil energy and mineral reserves and resources located on or below the Earth's surface and is intended to serve the needs for classification at a global level for governments, for industry and for financial reporting. UNFC-2009 is a generic system in which quantities are classified on the basis of the three fundamental criteria of economic and social viability (E), field project status and feasibility (F), and geological knowledge (G), using a numerical coding system. The aim of this paper is to explore whether the UNFC-2009 can meet the needs of all internal and external stakeholders.

Systematic method for resource rating with two applications to potential wilderness areas

International Nuclear Information System (INIS)

Voelker, A.H.; Wedow, H.; Oakes, E.; Scheffler, P.K.

1979-09-01

A versatile method was developed to rate the energy- and mineral-resource potentials of areas in which land-management and resource-development decisions must be reached with a minimum expenditure of money and time. The method surveys published and personal information on resources in the region being assessed, selects the most appropriate information, synthesizes the information into map overlays and tract descriptions, rates the potential of tracts for particular resources, rates the overall importance of each tract for resource development, and documents the ratings and their significance. Basic criteria considered by the assessment team include the favorability and certainty ratings, the overall availability of each rated resource within this country, the size of a given tract, economic factors, and the number of resources in a tract. The method was applied to two separate but roughly similar geologic regions, the Idaho-Wyoming-Utah thrust belt and the central Appalachians. Undeveloped tracts of national forestland in these regions that are being considered for possible designation under the Roadless Area Review and Evaluation (RARE II) planning process were rated for their resource value. Results support earlier indications that the 63 tracts comprising the western thrust belt possess a high potential for future resource development. Nearly one-half of these tracts were rated either 3 or 4. However, the wide spread of the importance ratings between 1 and 4 suggests that some tracts or portions of tracts can be added to the National Wilderness System without compromising resource development. The 72 eastern thrust belt tracts were given lower ratings, which indicates the reduced significance of the few remaining roadless areas in this region in satisfying the nation's near-term resource needs

It is first indicated how to evaluate the mining resources as a function of the cost of production and the degree of certainty in the knowledge of the deposit. A table is given of the world resources (at the beginning 1977) and resources and reserves are compared. There is a concordance between requirements and possible production until 1990. The case of France is examined: known reserves, present and future prospection, present production (In 1978 2200 T of U metal will be produced from 3 French processing plants), production coming from Cogema. A total production of 2000 T in 1980 and 10.000 in 1985 is expected [fr

Uranium resource assessments

International Nuclear Information System (INIS)

1981-01-01

The objective of this investigation is to examine what is generally known about uranium resources, what is subject to conjecture, how well do the explorers themselves understand the occurrence of uranium, and who are the various participants in the exploration process. From this we hope to reach a better understanding of the quality of uranium resource estimates as well as the nature of the exploration process. The underlying questions will remain unanswered. But given an inability to estimate precisely our uranium resources, how much do we really need to know. To answer this latter question, the various Department of Energy needs for uranium resource estimates are examined. This allows consideration of whether or not given the absence of more complete long-term supply data and the associated problems of uranium deliverability for the electric utility industry, we are now threatened with nuclear power plants eventually standing idle due to an unanticipated lack of fuel for their reactors. Obviously this is of some consequence to the government and energy consuming public. The report is organized into four parts. Section I evaluates the uranium resource data base and the various methodologies of resource assessment. Part II describes the manner in which a private company goes about exploring for uranium and the nature of its internal need for resource information. Part III examines the structure of the industry for the purpose of determining the character of the industry with respect to resource development. Part IV arrives at conclusions about the emerging pattern of industrial behavior with respect to uranium supply and the implications this has for coping with national energy issues

The aim of this study was to explore the relationships between job demands, job resourses, personal resourses and job satisfaction and to assess the usefulness of the Job Demands-Resources (JD-R) model in the explanation of these phenomena. The research was based on a sample of 500 social workers. The "Psychosocial Factors" and "Job satisfaction" questionnaires were used to test the hypothesis. The results showed that job satisfaction increased with increasing job accessibility and personal resources (r = 0.44; r = 0.31; p job resources and job demands [F(1.474) = 4.004; F(1.474) = 4.166; p job satisfaction. Moreover, interactions between job demands and job resources [F(3,474) = 2.748; p job demands and personal resources [F(3.474) = 3.021; p job satisfaction. The post hoc tests showed that 1) in low job demands, but high job resources employees declared higher job satisfaction, than those who perceived them as medium (p = 0.0001) or low (p = 0.0157); 2) when the level of job demands was perceived as medium, employees with high personal resources declared significantly higher job satisfaction than those with low personal resources (p = 0.0001). The JD-R model can be used to investigate job satisfaction. Taking into account fundamental factors of this model, in organizational management there are possibilities of shaping job satisfaction among employees.

Alberta Chamber of Resources: 1998 in review

International Nuclear Information System (INIS)

Simpson, R.

1999-01-01

Several key initiatives taken by the Alberta Chamber of Resources during 1998 are described. Among these initiatives special mention is made of strengthening the relations between the Chamber and the University of Calgary and the University of Alberta through regular contributions to business plan reviews, scholarships, and advisory committees. Working with the Department of Energy on a range of issues involving the environment, taxation, and mineral rights tenure is an area the ACR is involved. Hosting a workshop on the economic and social values and trade-offs in the green areas of Alberta and working with the University Alberta regarding the development of an advisory committee on forest resource valuation is another area. Strategizing the Oil Sands Task Force to strengthen it in the areas of industrial coordination, by-product utilization, the creation niche markets and product quality and investigating, through the Black Oil Pipeline Steering Committee, transportation, technological and marketing issues related to the oil sands are other interests. In the Mineral Sector, the Chamber facilitated discussions towards a Non-Energy Minerals and Mines Act, which among other long-range beneficial effects, prompted the provincial government to provide an additional $ 1.5 million to the Alberta Geological Survey. In the Utilities Sector, the Chamber continued to bring together various parties to work on common challenges and opportunities. Much interest has been generated also on upgraders and research facilitated by the Chamber either with members of the Alberta Research Council, or the National Centre for Upgrading Technology or similar organizations. This kind of facilitation helps the Chamber's member companies to realize cost reductions in development and application of new technologies

2009-01-01

A nation's endowment of nonfuel mineral resources, relative to the world's endowment, is a fundamental consideration in decisions related to a nation's economic and environmental well being and security. Knowledge of the worldwide abundance, distribution, and general geologic setting of mineral commodities provides a framework within which a nation can make decisions about economic development of its own resources, and the economic and environmental consequences of those decisions, in a global perspective. The information in this report is part of a U.S. Geological Survey (USGS) endeavor to evaluate the global endowment of both identified and undiscovered nonfuel mineral resources. The results will delineate areas of the world that are geologically permissive for the occurrence of undiscovered selected nonfuel mineral resources together with estimates of the quantity and quality of the resources. The results will be published as a series of regional reports; this one provides basic data on the identified resources and geologic setting, together with a brief appraisal of the potential for undiscovered mineral resources in Africa and the Middle East. Additional information, such as production statistics, economic factors that affect the mineral industries of the region, and historical information, is available in U.S. Geological Survey publications such as the Minerals Yearbook and the annual Mineral Commodity Summaries (available at http://minerals.usgs.gov/minerals).

Evaluation of uranium resources in Antarctica

International Nuclear Information System (INIS)

Zeller, E.J.; Dreschhoff, G.A.M.

1980-01-01

The continent of Antarctica comprises roughly nine per cent of the total land surface of the earth and is the only large land area that has been left almost totally unexplored for uranium resources. In 1976 the first systematic uranium resource evaluation, entitled Antarctica International Radiometric Survey, was started as a part of the US Antarctic Research Program. This project was staffed jointly by scientists from the University of Kansas and the Bundesanstalt fuer Geowissenschaften und Rohstoffe of the Federal Republic of Germany. The survey has continued for three antarctic field seasons and an extension of operations for the next four years has been approved. Two areas in the Transantarctic Mountains and one part of Marie Byrd Land have been surveyed by airborne gamma-ray spectrometric methods. The work that has been conducted demonstrates clearly that radiometric surveys can be performed successfully under the rigorous climatic conditions in Antarctica, and that significant and reproducible data can be obtained. So far no substantial concentrations of uranium have been detected but deposits of thorium minerals have been found. (author)

The 1980-1982 Geothermal Resource Assessment Program in Washington

Energy Technology Data Exchange (ETDEWEB)

Korosec, Michael A.; Phillips, William M.; Schuster, J.Eric

1983-08-01

Since 1978, the Division of Geology and Earth Resources of the Washington Department of Natural Resources has participated in the U.S. Department of Energy's (USDOE) State-Coupled Geothermal Resource Program. Federal and state funds have been used to investigate and evaluate the potential for geothermal resources, on both a reconnaissance and area-specific level. Preliminary results and progress reports for the period up through mid-1980 have already been released as a Division Open File Report (Korosec, Schuster, and others, 1981). Preliminary results and progress summaries of work carried out from mid-1980 through the end of 1982 are presented in this report. Only one other summary report dealing with geothermal resource investigations in the state has been published. An Information Circular released by the Division (Schuster and others, 1978) compiled the geology, geochemistry, and heat flow drilling results from a project in the Indian Heaven area in the south Cascades. The previous progress report for the geothermal program (Korosec, Schuster, and others, 1981) included information on temperature gradients measured throughout the state, heat flow drilling in the southern Cascades, gravity surveys for the southern Cascades, thermal and mineral spring investigations, geologic mapping for the White Pass-Tumac Mountain area, and area specific studies for the Camas area of Clark County and Mount St. Helens. This work, along with some additional studies, led to the compilation of the Geothermal Resources of Washington map (Korosec, Kaler, and others, 1981). The map is principally a nontechnical presentation based on all available geothermal information, presented as data points, tables, and text on a map with a scale of 1:500,000.

Evidence-based human resource management: a study of nurse leaders' resource allocation.

Science.gov (United States)

Fagerström, Lisbeth

2009-05-01

The aims were to illustrate how the RAFAELA system can be used to facilitate evidence-based human resource management. The theoretical framework of the RAFAELA system is based on a holistic view of humankind and a view of leadership founded on human resource management. Nine wards from three central hospitals in Finland participated in the study. The data, stemming from 2006-2007, were taken from the critical indicators (ward-related and nursing intensity information) for national benchmarking used in the RAFAELA system. The data were analysed descriptively. The daily nursing resources per classified patient ratio is a more specific method of measurement than the nurse-to-patient ratio. For four wards, the nursing intensity per nurse surpassed the optimal level 34% to 62.2% of days. Resource allocation was clearly improved in that a better balance between patients' care needs and available nursing resources was maintained. The RAFAELA system provides a rational, systematic and objective foundation for evidence-based human resource management. Data from a systematic use of the RAFAELA system offer objective facts and motives for evidence-based decision making in human resource management, and will therefore enhance the nurse leaders' evidence and scientific based way of working.

Germany is dependent on imports for its metalliferous natural resources. Although prices have been declining significantly in recent months, numerous raw materials such as platinum, cobalt and rare earth elements continue to be exposed to price and supply risks. To ensure that German industry can respond better to this situation in their procurement activities, the German Mineral Resources Agency (DERA) at BGR has developed a raw material monitoring system on behalf of the German government. DERA experts have con figured a screening method for the early identification of possible procurement risks. This is the platform which enables German companies to gain the specific advice they require. All of the most important information on this issue is bundled within DERA 's internet portal (www.deutsche-rohstoffagentur.de). BGR also provides its expertise in other important fields with great societal relevance. BGR has been advising the national commission on ''Storage of High-level Radioactive Waste'' since 2014. Due to their comprehensive research activities in the field of radioactive waste disposal, BGR scientists are important technical experts to which the commission can turn to for geological information and advice.

Stoichiometric imbalances between terrestrial decomposer communities and their resources: mechanisms and implications of microbial adaptations to their resources

Directory of Open Access Journals (Sweden)

Maria eMooshammer

2014-02-01

Full Text Available Terrestrial microbial decomposer communities thrive on a wide range of organic matter types that rarely ever meet their elemental demands. In this review we synthesize the current state-of-the-art of microbial adaptations to resource stoichiometry, in order to gain a deeper understanding of the interactions between heterotrophic microbial communities and their chemical environment. The stoichiometric imbalance between microbial communities and their organic substrates generally decreases from wood to leaf litter and further to topsoil and subsoil organic matter. Microbial communities can respond to these imbalances in four ways: first, they adapt their biomass composition towards their resource in a non-homeostatic behaviour. Such changes are, however, only moderate, and occur mainly because of changes in microbial community structure and less so due to cellular storage of elements in excess. Second, microbial communities can mobilize resources that meet their elemental demand by producing specific extracellular enzymes, which, in turn, is restricted by the C and N requirement for enzyme production itself. Third, microbes can regulate their element use efficiencies (ratio of element invested in growth over total element uptake, such that they release elements in excess depending on their demand (e.g., respiration and N mineralization. Fourth, diazotrophic bacteria and saprotrophic fungi may trigger the input of external N and P to decomposer communities. Theoretical considerations show that adjustments in element use efficiencies may be the most important mechanism by which microbes regulate their biomass stoichiometry. This review summarizes different views on how microbes cope with imbalanced supply of C, N and P, thereby providing a framework for integrating and linking microbial adaptation to resource imbalances to ecosystem scale fluxes across scales and ecosystems.

Up to now, it is estimated that more than 50 million tons of mineral wastes have been generated mining industries and deposited on the land in Korea. Much of cultivated land and hilly areas have been occupied by this wastes, which cause pollution of the environment. Utilization of the mineral wastes is preferable to stabilization because full use would both eliminate the waste and broaden the mineral resource base. Therefore, the development of utilization techniques of mineral wastes is very important not only for improving the environment but also for resource conservation. In countries with high population and poor natural resources like Korea, the utilization of these wastes is essential to decrease the environmental problem and the secure the resources and the study on this field play a important part. Therefore, the objective of this study is to develop the utilization techniques of the mineral wastes. In first year's research, the contents and scope of this study are 1) Present condition and Field Survey on the mineral wastes with respect of their utilization, 2) Reviews of Current effects and research to utilize mineral wastes, 3) Characterization of mineral wastes and environmental test, 4) Evaluation and study on the utilization.

1981-01-01

An approach to the evaluation of mineral resources is presented which takes into account a number of interrelated economical, technological and social aspects. The basic pattern of man and environment interaction in the process of mineral resources recovery is analyzed. Various approaches to classification of mineral resources are presented. Problems related to the development of a criterion and a system of factors characteristic for particular aspects of mineral resources management are discussed in detail. A dynamic approach to the economical evaluation of mineral reserves based on the form, magnitude, and the moment of time when the compensation of damage caused by the loss of resources in question becomes necessary, is presented. The influence of typical technical restrictions on the capacity of mining enterprises and the succession of the development of a field is discussed. Dynamic aspects of the evaluation of promising mineral reserves as a limited and nonreproducible natural resource is studied in detail. Actual methods and the state of current studies in the field of the economical evaluation of mineral deposits in the USSR, the CMEA countries and in capitalistic countries are presented.

Natural resource dependence, human capital accumulation, and economic growth: A combined explanation for the resource curse and the resource blessing

International Nuclear Information System (INIS)

Shao, Shuai; Yang, Lili

2014-01-01

In existing studies, no consensus has been reached on the relationship between natural resource dependence and human capital accumulation. To narrow the divergence, this paper carries out a normative research to explain the co-existence of the phenomena of the resource curse and the resource blessing based on an organic combination of conceptual and mathematical models. It first establishes a conceptual model to analyse the potential effects of the government's policy preference and natural resource development activities on human capital accumulation and economic growth. Furthermore, it develops an endogenous growth model to normatively illuminate the effects in the conceptual model and to explore the condition for the occurrence of the resource curse. The conceptual model analysis indicates that the rate of return on education investment and government behaviours play the crucial role in promoting the formation of the economic virtuous circle at the micro-level and macro-level, respectively, while resource development activities exert dual impacts on the circle. The main mechanisms in the conceptual model can be validated in the mathematical model. The rise in the subjective discount rate, the elasticity of intertemporal substitution, and resource goods price are adverse to the economic virtuous circle, while high-quality education and the institutional environment giving priority to manufacturing can become the necessary condition and sufficient condition for forming the circle, respectively. The allocation efficiency of production factors plays a decisive role in whether the blessing occurs, whereas sufficient human capital is an essential guarantee for evading the curse. - Highlights: • We conduct normative research combining a conceptual model and a mathematical model. • We discuss the potential impact of resource dependence on human capital and growth. • We explain the co-existence of the resource blessing and resource curse phenomena. �

Resource quality or competition: why increase resource acceptance in the presence of conspecifics?

Science.gov (United States)

Davis, Jeremy M; Nufio, César R; Papaj, Daniel R

2011-07-01

Some animal species increase resource acceptance rates in the presence of conspecifics. Such responses may be adaptive if the presence of conspecifics is a reliable indicator of resource quality. Similarly, these responses could represent an adaptive reduction in choosiness under high levels of scramble competition. Although high resource quality and high levels of scramble competition should both favor increased resource acceptance, the contexts in which the increase occurs should differ. In this paper, we tested the effect of social environment on egg-laying and aggressive behavior in the walnut fly, Rhagoletis juglandis, in multiple contexts to determine whether increased resource acceptance in the presence of conspecifics was better viewed as a response to increased host quality or increased competition. We found that grouped females oviposit more readily than isolated females when provided small (low-quality) artificial hosts but not when provided large (high-quality) artificial hosts, indicating that conspecific presence reduces choosiness. Increased resource acceptance was observed even when exposure to conspecifics was temporally or spatially separate from exposure to the resource. Finally, we found that individuals showed reduced aggression after being housed in groups, as expected under high levels of scramble competition. These results indicate that the pattern of resource acceptance in the presence of conspecifics may be better viewed as a response to increased scramble competition rather than as a response to public information about resource quality.

Library resources are prevalent on the Internet. Library catalogs, electronic books, electronic periodicals, periodical indexes, reference sources, and U.S. Government documents are available by telnet, Gopher, World Wide Web, and FTP. Comparatively few copyrighted library resources are available freely on the Internet. Internet implementations of library resources can add useful features, such as full-text searching. There are discussion lists, Gophers, and World Wide Web pages to help users keep up with new resources and changes to existing ones. The future will bring more library resources, more types of library resources, and more integrated implementations of such resources to the Internet.

Mineral Resource of the Month: Antimony

Science.gov (United States)

Guberman, David E.

2015-01-01

Antimony is a lustrous silvery-white semimetal or metalloid. Archaeological and historical studies indicate that antimony and its mineral sulfides have been used by humans for at least six millennia. The alchemist Basil Valentine is sometimes credited with “discovering” the element; he described the extraction of metallic antimony from stibnite in his treatise “The Triumphal Chariot of Antimony,” published sometime between 1350 and 1600. In the early 18th century, Jöns Jakob Berzelius chose the periodic symbol for antimony (Sb) based on stibium, which is the Latin name for stibnite.

Can individual and social patterns of resource use buffer animal populations against resource decline?

Directory of Open Access Journals (Sweden)

Sam C Banks

Full Text Available Species in many ecosystems are facing declines of key resources. If we are to understand and predict the effects of resource loss on natural populations, we need to understand whether and how the way animals use resources changes under resource decline. We investigated how the abundance of arboreal marsupials varies in response to a critical resource, hollow-bearing trees. Principally, we asked what mechanisms mediate the relationship between resources and abundance? Do animals use a greater or smaller proportion of the remaining resource, and is there a change in cooperative resource use (den sharing, as the availability of hollow trees declines? Analyses of data from 160 sites surveyed from 1997 to 2007 showed that hollow tree availability was positively associated with abundance of the mountain brushtail possum, the agile antechinus and the greater glider. The abundance of Leadbeater's possum was primarily influenced by forest age. Notably, the relationship between abundance and hollow tree availability was significantly less than 1:1 for all species. This was due primarily to a significant increase by all species in the proportional use of hollow-bearing trees where the abundance of this resource was low. The resource-sharing response was weaker and inconsistent among species. Two species, the mountain brushtail possum and the agile antechinus, showed significant but contrasting relationships between the number of animals per occupied tree and hollow tree abundance. The discrepancies between the species can be explained partly by differences in several aspects of the species' biology, including body size, types of hollows used and social behaviour as it relates to hollow use. Our results show that individual and social aspects of resource use are not always static in response to resource availability and support the need to account for dynamic resource use patterns in predictive models of animal distribution and abundance.

Resource management: Hotel Zira human resource management department analysis

Petrović Jelena

2015-01-01

Full Text Available The world is changing at a fast pace in a number of different areas, economically, politically technologically and socially. All these facts have strong impact on how managers organize their work. Traditionally they focus on delivering efficiency through large bureaucracies which are hierarchical in nature, very much around process and stability. What this mitigates against perhaps it is innovation and flexibility. A demand is no longer predictable and service has to be equally flexible for demand that exists nowadays. The emergence of post bureaucratic organizations is about being leaner, flatter and being much more network-based. Within that network employees are being empowered to take responsibility for producing innovations themselves. In order to speed up the process it is critical to systematize the process of managing people in the back office. Human Resource Management strategies are being transformed by internal social networks and social human resource technologies to better collaborative, transition into social enterprises, and change the positioning of human resource departments from back office to front office activities. All of these subjects are applied and the case study of hotel Zira human resource department is explained and showed in detail with the specific questionnaire. One of the main challenges that human resource management is also facing is the talent management and the number one responsibility of leadership is how to manage talent, how to attract it, utilize and eventually retain it.

This resource options report (ROR) fulfils regulatory requirements in British Columbia's two-year resource planning process. It identifies a wide range of resources and technologies that could be used to meet BC Hydro's future electricity demand. As such, it facilitates a transparent public review of resource options which include both supply-side and demand-side options. The resource options that will be used in the 2005 integrated electricity plan (IEP) were characterized. This ROR also documents where there is a general agreement or disagreement on the resource type characterization, based on the First Nations and Stakeholder engagement. BC Hydro used current information to provide realistic ranges on volume and cost to characterize environmental and social attributes. The BC Hydro system was modelled to assess the benefit and cost of various resource options. The information resulting from this ROR and IEP will help in making decisions on how to structure competitive acquisition calls and to determine the level of transmission services needed to advance certain BC Hydro projects. The IEP forecasts the nature and quantity of domestic resources required over the next 20 years. A strategic direction on how those needs will be met has been created to guide the management of BC Hydro's energy resources. Supply-side options include near-commercial technologies such as energy storage, ocean waves, tidal, fuel cells and integrated coal gasification combined cycle technology. Supply-side options also include natural gas, coal, biomass, geothermal, wind, and hydro. 120 refs., 39 tabs., 21 figs., 6 appendices

As a result of efficient use of natural resources production and use of goods and services can be made cheaper, which increases demand. However, that might partially offset savings in energy and other natural resources. This so-called 'rebound effect' can not be ignored. It is therefore worthwhile to keep that in formulating 'resource efficiency' policy [Dutch] Door efficienter om te gaan met natuurlijke hulpbronnen kunnen de productie en het gebruik van goederen en diensten goedkoper worden, waardoor de vraag ernaar toeneemt. Dat kan de besparingen op energie en andere natuurlijke hulpbronnen deels weer teniet doen. Dit 'rebound-effect' is niet verwaarloosbaar. Het is zinvol om hier bij beleid gericht op 'resource efficiency' rekening mee te houden.

Preliminary research on quantitative methods of water resources carrying capacity based on water resources balance sheet

Wang, Yanqiu; Huang, Xiaorong; Gao, Linyun; Guo, Biying; Ma, Kai

2018-06-01

Water resources are not only basic natural resources, but also strategic economic resources and ecological control factors. Water resources carrying capacity constrains the sustainable development of regional economy and society. Studies of water resources carrying capacity can provide helpful information about how the socioeconomic system is both supported and restrained by the water resources system. Based on the research of different scholars, major problems in the study of water resources carrying capacity were summarized as follows: the definition of water resources carrying capacity is not yet unified; the methods of carrying capacity quantification based on the definition of inconsistency are poor in operability; the current quantitative research methods of water resources carrying capacity did not fully reflect the principles of sustainable development; it is difficult to quantify the relationship among the water resources, economic society and ecological environment. Therefore, it is necessary to develop a better quantitative evaluation method to determine the regional water resources carrying capacity. This paper proposes a new approach to quantifying water resources carrying capacity (that is, through the compilation of the water resources balance sheet) to get a grasp of the regional water resources depletion and water environmental degradation (as well as regional water resources stock assets and liabilities), figure out the squeeze of socioeconomic activities on the environment, and discuss the quantitative calculation methods and technical route of water resources carrying capacity which are able to embody the substance of sustainable development.

Full text: Full text: Australia's world-leading uranium endowment appears to result from the emplacement of uranium enriched felsic igneous rocks in three major periods during the geological evolution of the continent. Australia has over 27% of the world's total reasonably assured uranium resources (RAR) recoverable at < US$80/kgU (which approximates recent uranium spot prices). Olympic Dam is the largest known uranium deposit, containing approximately 19% of global RAR (and over 40% of global inferred resources) recoverable at < US$80/kg U; the uranium is present at low concentrations and the viability of its recovery is underpinned by co-production of copper and gold. Most of Australia's other identified resources are within Ranger, Jabiluka, Koongarra, Kintyre and Yeelirrie, the last four of which are not currently accessible for mining. In 2004, Australia's three operating uranium mines - Ranger, Olympic Dam, and Beverley -produced 22% of global production. Canada was the only country to produce more uranium (29%) and Kazakhstan (9%) ranked third. Considerably increased uranium production has been recently foreshadowed from Australia (through developing a large open pit at Olympic Dam), Canada (mainly through opening of the Cigar Lake mine), and Kazakhstan (developing several new in situ leach mines). These increases should go a long way towards satisfying demand from about 2010. Olympic Dam has sufficient resources to sustain such increased production over many decades. Thorium is expected to be used in some future generations of nuclear reactors. Australia also has major (but incompletely quantified) resources of this commodity, mainly in heavy mineral sands deposits and associated with alkaline igneous rocks. It is inevitable that the international community will be looking increasingly to Australia to sustain its vital role in providing fuels for future nuclear power generation, given its world-leading identified resources, considerable potential for new

Full Text Available Background: The aim of this study was to explore the relationships between job demands, job resourses, personal resourses and job satisfaction and to assess the usefulness of the Job Demands-Resources (JD-R model in the explanation of these phenomena. Materials and Methods: The research was based on a sample of 500 social workers. The "Psychosocial Factors" and "Job satisfaction" questionnaires were used to test the hypothesis. Results: The results showed that job satisfaction increased with increasing job accessibility and personal resources (r = 0.44; r = 0.31; p < 0.05. The analysis of variance (ANOVA indicated that job resources and job demands [F(1.474 = 4.004; F(1.474 = 4.166; p < 0.05] were statistically significant sources of variation in job satisfaction. Moreover, interactions between job demands and job resources [F(3,474 = 2.748; p < 0.05], as well as between job demands and personal resources [F(3.474 = 3.021; p < 0.05] had a significant impact on job satisfaction. The post hoc tests showed that 1 in low job demands, but high job resources employees declared higher job satisfaction, than those who perceived them as medium (p = 0.0001 or low (p = 0.0157; 2 when the level of job demands was perceived as medium, employees with high personal resources declared significantly higher job satisfaction than those with low personal resources (p = 0.0001. Conclusion: The JD-R model can be used to investigate job satisfaction. Taking into account fundamental factors of this model, in organizational management there are possibilities of shaping job satisfaction among employees. Med Pr 2013;64(2:217–225

(4) The supporting service industry chain of mineral resources industry which formed a bridge between miner-al resource Industry and socio-economic system. (5) The repairing of mine ecological environment industry chain which connects the mineral resource industry and eco-environment system.

Protection of mineral deposits - a way towards difficult compromises

Radwanek-Bąk, Barbara; Nieć, Marek

2014-05-01

Mineral deposits are non-renewable natural resources. Their protection and reasonable exploitation are crucial requests resulting from sustainable development principles. Those are also fundamental issues in frame of the intergeneration justice and fairness concept. Protection of mineral resources should be based on interrelated activities: maintaining the possibility of economic use of the identified mineral resources, reduced consumption of mineral resources and ensuring satisfactory results of new prospecting and development of innovative technologies for the mineral resources base. The main problem with guarantee to the use of mineral resources is the accessibility to sites with documented deposits and prospective areas of their occurrence. Often, this contradicts with the interests of residents, planners and needs of the biotic environment protection, thus is often a source of conflicts. Legislative regulations are necessary to mitigate such arguable matters. SWOT analysis carried out with respect to introducing such legal regulations serves to identify the sources of conflicts and difficulties associated with their solution. Consensus reaching is a difficult task, so all decision makers are required to show their mutual understanding and willingness to achieve the goals taking into consideration all benefits for the population (including future generations). Foundations for finding the middle ground are: making the communities aware of their demands on minerals and of indispensable conditions for satisfying these demands; providing complete and accessible information; factual, non-emotional negotiations between decision makers and the public.

The social sciences have become increasingly important in understanding natural resource management contexts and audiences, and are essential in design and delivery of effective and durable management strategies. Yet many agencies and organizations do not have the necessary resource management. We draw on the textbook definition of HD: how and why people value natural resources, what benefits people seek and derive from those resources, and how people affect and are affected by those resources and their management (Decker, Brown, and Seimer 2001). Clearly articulating how HD information can be used and integrated into natural resource management planning and decision-making is an important challenge faced by the HD field. To address this challenge, we formed a collaborative team to explore the issue of HD capacity-building for natural resource organizations and to advance the HD field. We define HD capacity as activities, efforts, and resources that enhance the ability of HD researchers and practitioners and natural managers and decision-makers to understand and address the social aspects of conservation.Specifically, we sought to examine current barriers to integration of HD into natural resource management, knowledge needed to improve HD capacity, and existing HD tools, resources, and training opportunities. We conducted a needs assessment of HD experts and practitioners, developed a framework for considering HD activities that can contribute both directly and indirectly throughout any phase of an adaptive management cycle, and held a workshop to review preliminary findings and gather additional input through breakout group discussions. This paper provides highlights from our collaborative initiative to help frame and inform future HD capacity-building efforts and natural resource organizations and also provides a list of existing human dimensions tools and resources.

LHCb: Self managing experiment resources

CERN Multimedia

Stagni, F

2013-01-01

Within this paper we present an autonomic Computing resources management system used by LHCb for assessing the status of their Grid resources. Virtual Organizations Grids include heterogeneous resources. For example, LHC experiments very often use resources not provided by WLCG and Cloud Computing resources will soon provide a non-negligible fraction of their computing power. The lack of standards and procedures across experiments and sites generated the appearance of multiple information systems, monitoring tools, ticket portals, etc... which nowadays coexist and represent a very precious source of information for running HEP experiments Computing systems as well as sites. These two facts lead to many particular solutions for a general problem: managing the experiment resources. In this paper we present how LHCb, via the DIRAC interware addressed such issues.

The main emphasis is on the asset management in educational sphere and optimizationopportunities of organizational processes. The human, logistical, technical, informational and time resources ofmanagerial activity are outlined and specified from the strategic perspective and effectiveness standpoint. The necessary criteria of a strategic resource are identified as the value, rarity, originality and indispensability. The author makes a conclusion about the priority of human resources in the value hierarchy of social organization in the era of information society. The paper demonstrates both the theoretical and practical ways and means of raising the effectiveness and efficiency of educational institutions, as well as the constant need for teacher’s training, retraining, and stimulation of self-education. The investment in human resources and motivating environment, aimed at developing the potential of academic staff and other employees of educational institutions, benefits both the managers and employees alike and leads to social partnership, harmony, and conciliation of economic and social interests within the organization.

Nonregenerative natural resources in a sustainable system of energy supply.

Science.gov (United States)

Bradshaw, Alex M; Hamacher, Thomas

2012-03-12

Following the lead of the European Union in introducing binding measures to promote the use of regenerative energy forms, it is not unreasonable to assume that the global demand for combustible raw materials for energy generation will be reduced considerably in the second half of this century. This will not only have a favourable effect on the CO(2) concentration in the atmosphere, but will also help preserve fossil fuels-important as raw materials in the chemical industry-for future generations. Nevertheless, associated with the concomitant massive shift to regenerative energy forms, there will be a strong demand for other exhaustible raw materials, in particular metals, some of which are already regarded as scarce. After reviewing the debate on mineral depletion between "cornucopians" and "pessimists", we discuss the meaning of mineral "scarcity", particularly in the geochemical sense, and mineral "exhaustion". The expected drastic increase in demand for mineral resources caused by demographic and societal pressures, that is, due to the increase in in-use stock, is emphasised. Whilst not discussing the issue of "strong" versus "weak" sustainability in detail, we conclude that regenerative energy systems-like nearly all resource-consuming systems in our society-do not necessarily satisfy generally accepted sustainability criteria. In this regard, we discuss some current examples, namely, lithium and cobalt for batteries, rare earth-based permanent magnets for wind turbines, cadmium and tellurium for solar cells and copper for electrical power distribution.

Full Text Available The NIF Registry developed and maintained by the Neuroscience Information Framework is a cooperative project aimed at cataloging research resources, e.g., software tools, databases and tissue banks, funded largely by governments and available as tools to research scientists. Although originally conceived for neuroscience, the NIF Registry has over the years broadened in the scope to include research resources of general relevance to biomedical research. The current number of research resources listed by the Registry numbers over 13K. The broadening in scope to biomedical science led us to re-christen the NIF Registry platform as SciCrunch. The NIF/SciCrunch Registry has been cataloging the resource landscape since 2006; as such, it serves as a valuable dataset for tracking the breadth, fate and utilization of these resources. Our experience shows research resources like databases are dynamic objects, that can change location and scope over time. Although each record is entered manually and human-curated, the current size of the registry requires tools that can aid in curation efforts to keep content up to date, including when and where such resources are used. To address this challenge, we have developed an open source tool suite, collectively termed RDW: Resource Disambiguator for the (Web. RDW is designed to help in the upkeep and curation of the registry as well as in enhancing the content of the registry by automated extraction of resource candidates from the literature. The RDW toolkit includes a URL extractor from papers, resource candidate screen, resource URL change tracker, resource content change tracker. Curators access these tools via a web based user interface. Several strategies are used to optimize these tools, including supervised and unsupervised learning algorithms as well as statistical text analysis. The complete tool suite is used to enhance and maintain the resource registry as well as track the usage of individual

Canada is renowned for the wealth of its natural resources: vast forests and rich deposits of minerals, including uranium, oil and gas. Canada is also blessed with a variety of sources of energy, including nuclear energy. We understand that a healthy, prosperous, and sustainable society depends on using these resources wisely. Sustainable natural resources development needs to strike tile right balance among our economic, environmental and social priorities. Thus the focus of the Nuclear Energy Agency's third Forum for Stakeholder Confidence National Workshop in Ottawa October 15-19, 2002, on social considerations for increasing and maintaining public confidence in the long-term management of radioactive waste is of particular interest to us. We hope that Canada can provide insight into these issues by discussing our recent successes with-the FSC, namely the Government of Canada agreement with communities in the Port Hope area of southern Ontario on the long-term management of historic low level radioactive waste, and the development of the Nuclear Fuel Waste Act. We look forward to sharing our experience with you and learning from your experience. I wish all FSC participants and the wide range of Canadian stakeholders an interesting visit to the Port Hope area and stimulating discussions during your Workshop in Ottawa. (author)

Exhaustible resources and economic growth: the case of uranium mining in Saskatchewan

International Nuclear Information System (INIS)

Campbell, H.F.

1984-09-01

This study examines the effect of a booming natural resource sector on regional economic growth, with particular attention to the impact of regional government policy on mineral rent taxation and the allocation of resource revenues. The author's approach is first to document the relevant theory and then to apply it to the case of the uranium industry in Saskatchewan. Governments often hold the view that a significant portion of resource rents flowing from the boom should be appropriated by the public sector. The usual arguments of efficiency and equity are explained, as is their applicability to uranium in Saskatchewan. The model is extended to include provincial tax and expenditure policies. Chapter 2 concentrates on mineral taxes and examines their various effects on the behaviour of firms with respect to exploration and extraction. The theory about the effects of mineral taxes on exploration and extraction is reviewed and is subsequently used to anticipate the effect of taxes on uranium mining. The Saskatchewan Uranium Royalty is explicitly considered in a quantitative model to analyse the effect on the rate of extraction on the Key Lake Mine. It is agreed that taxes collected by the Saskatchewan government are corrective in nature in that they lower the rate of extraction and make up for certain market failures and improve efficiency of resource use. It is not accepted, however, that the allocation of these taxes contributes to economic efficiency. Plentiful low cost uranium reserves are predicted but government policy is likely to limit rapid expansion. Weighing these factors and the world uranium market, uranium production forecasts are derived and an estimate is made of the impact of the industry on economic growth in Saskatchewan. The contribution to Gross Domestic Provincial Product in 2000 could be as high as 10% of the 1980 GDPP level and the contribution to employment as high as 9% of 1980 nonagricultural employment. The reader is cautioned that the

This work presents a geoscientific map and database for geology, mineral and energy resources of Ethiopia in a digital form at a scale of 1 : 2,000,000, compiled from several sources. The final result of the work has been recorded on CD-ROM in GIS format. Metallic resources (precious, rare, base and ferrous-ferroalloy metals) are widely related to the metamorphic meta-volcano-sedimentary belts and associated intrusives belonging to various terranes of the Arabian-Nubian Shield, accreted during the East and West Gondwana collision (Neoproterozoic, 900-500 Ma). Industrial minerals and rock resources occur in more diversified geological environments, including the Proterozoic basement rocks, the Late Paleozoic to Mesozoic sediments and recent (Cenozoic) volcanics and associated sediments. Energy resources (oil, coal, geothermal resources) are restricted to Phanerozoic basin sediments and Cenozoic volcanism and rifting areas.

Zhang, Bo; Peng, Beihua; Liu, Mingchu

2012-01-01

This paper presents an overview of the resources use and environmental impact of the Chinese industry during 1997-2006. For the purpose of this analysis the thermodynamic concept of exergy has been employed both to quantify and aggregate the resources input and the environmental emissions arising from the sector. The resources input and environmental emissions show an increasing trend in this period. Compared with 47568.7 PJ in 1997, resources input in 2006 increased by 75.4% and reached 83437.9 PJ, of which 82.5% came from nonrenewable resources, mainly from coal and other energy minerals. Furthermore, the total exergy of environmental emissions was estimated to be 3499.3 PJ in 2006, 1.7 times of that in 1997, of which 93.4% was from GHG emissions and only 6.6% from "three wastes" emissions. A rapid increment of the nonrenewable resources input and GHG emissions over 2002-2006 can be found, owing to the excessive expansion of resource- and energy-intensive subsectors. Exergy intensities in terms of resource input intensity and environmental emission intensity time-series are also calculated, and the trends are influenced by the macroeconomic situation evidently, particularly by the investment-derived economic development in recent years. Corresponding policy implications to guide a more sustainable industry system are addressed.

State Electricity Regulatory Policy and Distributed Resources: Accommodating Distributed Resources in Wholesale Markets

Energy Technology Data Exchange (ETDEWEB)

Weston, F.; Harrington, C.; Moskovitz, D.; Shirley, W.; Cowart, R.; Sedano, R.

2002-10-01

Distributed resources can provide cost-effective reliability and energy services - in many cases, obviating the need for more expensive investments in wires and central station electricity generating facilities. Given the unique features of distributed resources, the challenge facing policymakers today is how to restructure wholesale markets for electricity and related services so as to reveal the full value that distributed resources can provide to the electric power system (utility grid). This report looks at the functions that distributed resources can perform and examines the barriers to them.

A Resource Perspective on the Work-Home Interface: The Work-Home Resources Model

Science.gov (United States)

ten Brummelhuis, Lieke L.; Bakker, Arnold B.

2012-01-01

The objective of this article is to provide a theoretical framework explaining positive and negative work-home processes integrally. Using insights from conservation of resources theory, we explain how personal resources (e.g., time, energy, and mood) link demanding and resourceful aspects of one domain to outcomes in the other domain. The…

Resource specialization, customer orientation, and firm performance: an empirical investigation of valuable resources

DEFF Research Database (Denmark)

Sørensen, Hans Eibe

2011-01-01

This study contributes to the strategic marketing research by empirically investigating the role of customer orientation in explaining how firms leverage their specialized but vulnerable resources. The aim is thus to explore a subset of the means by which resources become valuable to the firm...... – the first criterion for a strategic resource. Hypotheses are developed and tested using CEO questionnaire responses from a sample of manufacturing firms and census accounting data. The results show that there is a strong link between industry-specific resources and return on assets for firms with high...... levels of customer orientation. We also report that firm-specific resources are unrelated to firm performance and that a customer orientation – investigated in isolation, may be detrimental to firm performance. Research and managerial implications are discussed....

Resource revenues report

International Nuclear Information System (INIS)

2004-01-01

Preliminary forecasts of resource revenues that may be forthcoming with the lifting of the moratorium on the west coast of British Columbia were presented. The forecasts are based on the development scenarios of one natural gas project in the Hecate Strait, and one oil project in the Queen Charlotte Sound. Both projects were assessed in an effort to demonstrate some of the potential resource revenues and public benefits that may be possible from offshore development in the province. Resource revenues provide the return-on-investments to the resource developer and public benefits in the form of taxes, royalties, lease payments and related fees to all levels of governments. Much of the revenues generated from the British Columbia offshore oil and gas development will accrue as income taxes. A public energy trust offers a way to transform non-renewable resource revenues into a renewable source of wealth for citizens of the province. The report presents estimates of project investment, pipeline capacity limitation, operating costs for offshore platforms, and earnings. It was estimated that about $2.0 billion in public benefits would be generated from combined project revenues of $6.9 billion. Information was obtained from offshore leaseholders as well as pipeline and engineering companies. refs., tabs., figs

Entrepreneurship as re-sourcing

DEFF Research Database (Denmark)

Korsgaard, Steffen; Anderson, Alistair; Gaddefors, Johan

Objectives The purpose of this paper is to re-examine the concept of entrepreneurship in light of the current financial and environmental crisis and its socio-spatial impact. Building on Hudson’s analysis of production in late-capitalist societies, we identify problems inherent in the dominant...... of grounding in material reality, lacking emphasis on environmental externalities and an impoverished conceptualization of spatial relations. Comparing this analysis with the dominant opportunistic image of the entrepreneur, leads us to formulate a critique of this image. In formulating an alternative we build...... The paper presents a “new image” of entrepreneurship as re-sourcing. The concept of re-sourcing emphasizes the dual meaning of the word resource as both a stock of supply and strategy or action adopted in adverse circumstances. Re-sourcing thus signifies a shift in focus from opportunities to resources...

Resource price turbulence and macroeconomic adjustment for a resource exporter. A conceptual framework for policy analysis

International Nuclear Information System (INIS)

Cox, Grant M.; Harvie, Charles

2010-01-01

Increased global demand for energy and other resources, particularly from the rapidly developing economies of China and India and the opening up of global resource markets to global investors and speculative activity, has resulted in considerable recent turbulence in resource prices. The recent magnitude of change in resource prices, both positive and negative, and their macroeconomic implications is of considerable contemporary importance to both resource importing and exporting economies. For a resource exporting economy, such as that of Australia, the recent resource price boom has resulted in: increased government taxation revenue, increased employment and wages in the resource and resource related sectors, increased spending in the domestic economy that contributed to buoyant economic growth, increased resource exports to the booming economies of China and India and contributed to a stronger domestic currency with beneficial effects upon inflation. On the other hand these developments have had adverse effects on the non-resource sector by: subjecting it to more intense competition for limited resources, contributing to a loss of international competitiveness and reduced exports arising from a stronger exchange rate, reducing employment in the relatively more labour intensive non-resource sector, and contributing to an eventual slow down in the overall economy. These positive and negative effects, and the overall impact of a resource price boom, require a fundamentally closer analysis of the structure of the economy under scrutiny. In this context the policy response by government is likely to be pivotal in determining the overall macroeconomic outcomes from a resource price boom. The aim of this paper is to develop a generic analytical framework to appraise economic outcomes in the wake of a resource price boom for a resource producing and exporting economy. To this end a dynamic long run macroeconomic model is developed, emphasising the important role and
