    This paper describes the work realized at the 'Centre Europeen d'Archeometrie' to highlight the utility of high-energy alpha PIXE in the particular field of archaeometry and to introduce the developments done and to be done to complete the knowledge of high-energy alpha PIXE. It starts with the comparison of the yield and the noise background between several alpha particle beams and the comparison between alpha particle and proton beams on different thick and thin references. After, this paper depicts the developments done at the 'Institut de Physique Nucleaire, Atomique et Spectroscopie' to perform such high-energy experiments, first on standards and later on cultural heritage objects. Moreover, it introduces the problematics of such beams for the quantification in PIXE by the intermediary of the knowledge of the ionization and X-ray production cross-sections and also the developments done to answer to this serious lack in the databases.

    Full Text Available This paper assesses the impact that the introduction of scientific methods for materials characterisation (conventionally grouped under the label of Archaeometry has had in the methodological configuration of Spanish archaeology over the last two decades. This is achieved through a bibliometric study of publications dealing with characterisation of archaeological ceramics from Andalucía (southern Spain. The variables handled in this study include aspects such as the number of sampled sites and items, their geographical provenance, the chronological and functional dimensions of the archaeological contexts they were taken from as well as the analytical techniques employed in their study.

    Este artículo intenta valorar el impacto que la introducción de métodos de caracterización de materiales procedentes de la física y la química (y agrupados habitualmente bajo la denominación genérica de Arqueometría ha tenido en la configuración metodológica de la investigación arqueológica de nuestro país durante las últimas dos décadas. Para ello se realiza un análisis bibliométrico de un ámbito específico de la aplicación de las técnicas arqueométricas, cual es el de la caracterización de materiales cerámicos dentro de la Arqueología andaluza. Las variables tenidas en cuenta incluyen aspectos tales como la cantidad de sitios arqueológicos muestreados y de muestras analizadas, su procedencia geográfica, los contextos cronológicos y funcionales de los que las muestras fueron tomadas y las técnicas analíticas empleadas.

    Archaeometry is an interdisciplinary research area involved in the development and use of scientific methods in order to answer questions concerned with the human history. In this way the knowledge of archaeological objects through advanced chemical and physical analyses permits a better preservation and conservation of the cultural heritage and also reveals materials and technologies used in the past. In this sense, analytical techniques play an important role in order to provide chemical information about cultural objects. Considering the non destructive characteristic of this study, analytical techniques must be adequate in order to prevent any alteration or damage and in addition to allow the conservation of their integrity. Taking into account the irreplaceable character of the archaeological and artistic materials considered in this study, analytical techniques must be adequate in order to prevent any alteration or damage and in addition to allow the conservation of their integrity. Total Reflection X-ray Fluorescence Spectrometry as a geometric variant of conventional X-ray fluorescence is a proved microanalytical technique considering the small amount of sample required for the analysis. A few micrograms are enough in order to reveal valuable information about elemental composition and in this context it is highly recommended for artwork studies. In this paper a case study is presented in which Total Reflection X-Ray Fluorescence Spectrometry has been successfully employed in the archaeometry field. Examples from Argentinean cultural heritage sites related with the determination of pigments in paintings on canvas and in rock sites as well as in underwater archaeology research are shown.

    Neutron radiation meets the demand for a versatile diagnostic probe for collecting information from the interior of large, undisturbed museum objects or archaeological findings. Neutrons penetrate through coatings and corrosion layers deep into centimetre-thick materials, a property that makes them ideal for non-destructive examination of objects for which sampling is impractical or unacceptable. A particular attraction of neutron techniques for archaeologists and conservation scientists is the prospect of locating hidden materials and structures inside objects. Time-of-flight (TOF) neutron diffraction allows for the examination of mineral and metal phase contents, crystal structures, grain orientations, and microstructures as well as micro- and macro strains. A promising application is texture analysis which may provide clues to the deformation history of the material, and hence to specific working processes. Here we report on instructive examples of TOF neutron diffraction, including phase analyses of medieval Dutch tin-lead spoons, texture analyses of bronze specimens as well as of 16th-century silver coins.

  10. Radiation applications in art and archaeometry X-ray fluorescence applications to archaeometry. Possibility of obtaining non-destructive quantitative analyses

    Energy Technology Data Exchange (ETDEWEB)

    Milazzo, Mario E-mail: mario.milazzo@unimi.it

    2004-01-01

    The possibility of obtaining quantitative XRF analysis in archaeometric applications is considered in the following cases: - Examinations of metallic objects with irregular surface: coins, for instance. - Metallic objects with a natural or artificial patina on the surface. - Glass or ceramic samples for which the problems for quantitative analysis rise from the non-detectability of matrix low Z elements. The fundamental parameter method for quantitative XRF analysis is based on a numerical procedure involving he relative values of XRF lines intensity. As a consequence it can be applied also to the experimental XRF spectra obtained for metallic objects if the correction for the irregular shape consists only in introducing a constant factor which does not affect the XRF intensity relative value. This is in fact possible in non-very-restrictive conditions for the experimental set up. The finenesses of coins with a superficial patina can be evaluated by resorting to the measurements of Rayleigh to Compton scattering intensity ratio at an incident energy higher than the one of characteristic X-ray. For glasses and ceramics the measurements of the Compton scattered intensity of the exciting radiation and the use of a proper scaling law make possible to evaluate the matrix absorption coefficients for all characteristic X-ray line energies.

    Neutron activation analysis, Mössbauer spectroscopy and X-ray diffraction techniques were used to characterize pre-Hispanic potsherds and modern ceramic pottery, samples of which were collected in Tenexco, San Luis Potosi, Mexico. Elementary and spectroscopic analysis showed differences between ancient and modern ceramics. While the modern ceramics studied were practically new and not used at all, the ancient ones were probably used in domestic or ceremonial activities. Besides, the latter were kept buried for a long time, and it is quite probable that their manufacture was also slightly different from that of the former. These assumptions could provide the clues to understand some of the observed differences between the composition of ancient and modern ceramics whose raw materials may have the same origin.

    Chemical analysis of ancient residues of pharmaceutical or cosmetic preparations such as balms or ointments is made problematic by the high complexity of these mixtures, composed of organic and inorganic materials. Consequently, a multi-analytical approach and special caution in the interpretation of the results are necessary. In order to contribute to the improvement of analytical strategies for the characterization of complex residues and to reconstruct ancient medical practices, a replica of a pharmaceutical formulation of the seventeenth century was prepared in the laboratory according to a historically documented recipe. In a round robin exercise, a portion of the preparation was analysed as a blind sample by 11 laboratories using various analytical techniques. These included spectroscopic, chromatographic and mass spectrometric methods. None of the laboratories was able to completely reconstruct the complex formulation, but each of them gave partial positive results. The round robin exercise has demonstrated that the application of a multi-analytical approach can permit a complete and reliable reconstruction of the composition. Finally, on the basis of the results, an analytical protocol for the study of residues of ancient medical and pharmaceutical preparations has been outlined.

    Starting on a laboratory developed portable X-ray fluorescence (PXRF) spectrometer; three different analytical results can be performed: analysis of chemical elements, analysis of major chemical crystalline phase and structural analysis, which represents a contribution to a new, low cost development of portable X-ray analyzer; since these results are respectively obtained with independent equipments for X-ray fluorescence, X-ray diffraction and radiography. Detection limits of PXRF were characterized using standard reference materials for ceramics, glass, bronze and bones, which are the main materials requiring quantitative analysis in art and archeological objects. A setup for simultaneous energy dispersive X-ray fluorescence and diffraction (ED (XRF-XRD)) in the reflection mode has been tested for in situ and non-destructive analysis according to the requirements of art objects inspection. The system uses a single low power X-ray tube and an X-ray energy dispersive detector to measure X-ray diffraction spectrum at a fixed angle. Application to the identification of jadeite-jade mineral in archeological objects by XRD is presented. A local high resolution radiography image obtained with the same low power X-ray tube allows for studies in painting and archeological bones.

    The book that now is presented is formed by twelve articles that approach from different perspective topics as the archaeological prospecting, the analysis of the pre hispanic and colonial ceramic, the obsidian and the mural painting, besides dating and questions about the data ordaining. Following the chronological order in which the exploration techniques and laboratory studies are required, there are presented in the first place the texts about the systematic and detailed study of the archaeological sites, later we pass to relative topics to the application of diverse nuclear techniques as PIXE, RBS, XRD, NAA, SEM, Moessbauer spectroscopy and other conventional techniques. The multidisciplinary is an aspect that highlights in this work, that which owes to the great specialization of the work that is presented even in the archaeological studies including in the open ground of the topography, mapping, excavation and, of course, in the laboratory tests. Most of the articles are the result of several years of investigation and it has been consigned in the responsibility of each article. The texts here gathered emphasize the technical aspects of each investigation, the modern compute systems applied to the prospecting and the archaeological mapping, the chemical and physical analysis of organic materials, of metal artifacts, of diverse rocks used in the pre hispanic epoch, of mural and ceramic paintings, characteristics that justly underline the potential of the collective works.

  20. Performance of hybrid angle-energy dispersive X-ray diffraction and fluorescence portable system for non-invasive surface-mineral identification in Archaeometry

    CERN Document Server

    Cuevas, Ariadna Mendoza

    2016-01-01

    Low power energy dispersive XRD-XRF portable instruments equipped with multiple angle scanning can take advantage of the shorter acquisition time of EDXRD with respect to ADXRD, and bring closer higher accuracy and resolution of inter-planar distance with those obtained by ADXRD. The data produced by this new hybrid configuration is correlated in the sense that a single XRF or XRD specimen appear in multiple spectra (the later shifted in energy for differing angles). Hence, for fully benefit from the richer data released by this configuration, the analysis should not be confined to the independent processing of the spectra, specialized hybrid data processing should be conceived. We previously reported some advances in the processing of the resulting 3D data (intensity, energy and angle). Here the analytical performance of the first hybrid angle-energy dispersive X-ray diffraction and fluorescence portable system is assessed for non-invasive surface mineral analysis of samples relevant for archaeometrical appl...

    @@ Being critical in the development of the human civilization, the ancient salt-making has been an important research issue for both historians and archaeologists. Since salt dissolves in water, it is difficult to tell whether the salt in archaeological samples was caused by human production of salt or underground water. So how to judge the existence of salt production has been a world-wide problem in archaeology and archaeometry.

    Archaeometry is an area established in the international community since the 60s, with extensive use of atomic-nuclear methods in the characterization of art, archaeological and cultural heritage objects in general. In Brazil, however, until the early '90s, employing methods of physics, only the area of archaeological dating was implemented. It was only after this period that Brazilian groups became involved in the characterization of archaeological and art objects with these methodologies. The Laboratory of Applied Nuclear Physics, State University of Londrina (LFNA/UEL) introduced, pioneered in 1994, Archaeometry and related issues among its priority lines of research, after a member of LFNA has been involved in 1992 with the possibilities of tomography in archaeometry, as well as the analysis of ancient bronzes by EDXRF. Since then, LFNA has been working with PXRF and Portable Raman in several museums in Brazil, in field studies of cave paintings and in the laboratory with material sent by archaeologists, as well as carrying out collaborative work with new groups that followed in this area. From 2003/2004 LAMFI/DFN/IFUSP and LIN/COPPE/UFRJ began to engage in the area, respectively with methodologies using ion beams and PXRF, then over time incorporating other techniques, followed later by other groups. Due to the growing number of laboratories and institutions/archaeologists/conservators interested in these applications, in may 2012 was created a network of available laboratories, based at http://www.dfn.if.usp.br/lapac. It will be presented a panel of recent developments and applications of these methodologies by national groups, as well as a sampling of what has been done by leading groups abroad.

    When a multilayered material is analyzed by means of energy-dispersive X-ray fluorescence analysis, then the X-ray ratios of Kα/ Kβ, or Lα/ Lβ and Lα/ Lγ, for an element in the multilayered material, depend on the composition and thickness of the layer in which the element is situated, and on the composition and thickness of the superimposed layer (or layers). Multilayered samples are common in archaeometry, for example, in the case of pigment layers in paintings, or in the case of gilded or silvered alloys. The latter situation is examined in detail in the present paper, with a specific reference to pre-Columbian alloys from various museums in the north of Peru.

    The characterization of technical indicators contained in the painting mural should follow a minim methodology from their discovery in the archaeological excavations until their analysis in the laboratory, with the purpose of rescuing diagnostic elements that mark the stages of socio cultural development in the towns. With this spirit it was carried out the present study analyzing some fragments of the Teotihuacan mural painting. The analysis consisted on applying some of the analytical techniques with particle beams used for archaeometry like the Proton induced X-ray emission (PIXE) and the particle elastic backscattering (RBS), due to it is treated of complementary techniques, very sensitive, of multielemental character, but mainly because its are non destructive analytical techniques.

    The archaeometric application of IBA is possible because in the majority of cases the working conditions are such that no damage and in particular visible damage is produced on the valuable unique samples. Obviously this does not mean that cultural heritage materials do not experience, like all other, the probe-target interaction and effects, but that the interaction is controllable and kept below safe limits. This work has aimed at establishing within which limits the potential damage is negligible or the analysis is viable on the basis of the benefit/cost ratio, making use of the information which is available not only from archaeometry but also from the more 'aggressive' materials science applications of ion beams.

    A new external microbeam system has been installed recently at the +45 deg. beam line of the 3 MV Pelletron accelerator at the Centro Nacional de Aceleradores (Sevilla, Spain). The facility, based on the system from Oxford Microbeams (OM), includes two sets of slits, a doublet of magnetic quadrupole focusing lenses, a Faraday cup and an accurate positioning device. In addition, a beam profile monitor (BPM) and a quartz viewer have been installed in the line to facilitate the microbeam production. The first PIXE application of the new facility was made in the field of Archaeometry, on the study of Tartesic gold artefacts (700-500 BC, SW of Spain) from Ebora and other archaeological sites. The aim of the analysis was to perform an exhaustive and systematic study about the soldering procedures that were employed by the goldsmiths along the Valley of Guadalquivir River after the Phoenician colonisation.

    2014-12-13

    Raman spectroscopy has proved to be a very useful technique in astrobiology research. Especially, working with mobile instrumentation during fieldwork can provide useful experiences in this field. In this work, we provide an overview of some important aspects of this research and, apart from defining different types of mobile Raman spectrometers, we highlight different reasons for this research. These include gathering experience and testing of mobile instruments, the selection of target molecules and to develop optimal data processing techniques for the identification of the spectra. We also identify the analytical techniques that it would be most appropriate to combine with Raman spectroscopy to maximize the obtained information and the synergy that exists with Raman spectroscopy research in other research areas, such as archaeometry and forensics.

    The "IPNAS" laboratory, in collaboration with the "Centre Européen d'Archéométrie" is partly focused on material analysis by means of IBA techniques: PIXE, PIGE and RBS. A new transport beam line has been developed at our CGR-520 MeV cyclotron to analyze Cultural Heritage objects using these techniques. This facility allows us to produce proton and alpha particle beams with energies up to 20 MeV. A vacuum chamber dedicated to X-ray production and Non-Rutherford cross-section measurements has been recently constructed. After determination of the chamber's geometry for X-ray detection using thin foils of several elements (11 ⩽ Z ⩽ 82) and 3 MeV proton beams, the measurement of the X-ray production cross-sections in the 6-12 MeV energy range has started using alpha particle beams on light element targets. These experiments contribute to the filling a serious lack of experimental values for alpha particles of this particular energy range in databases. The recent decision to focus our work on the alpha particle interaction with light elements was taken because of the high interest of the low Z elements in the field of archaeometry.

    New improvements on our archaeometry line at the cyclotron of the Institute of Nuclear and Atomic Physics and of Spectrometry of the University of Liège have allowed the use of PIXE/PIGE and IBIL in-air for the analysis of cultural heritage objects. The extraction is performed through a 100 nm thick Si 3N 4 window. The detection set-up consists now of two X-ray and one γ-ray detectors, together with a fiber optic UV-visible spectrometer. This set-up has already been tested for the analysis of modern corundum [1] and is now adapted to the analysis of archaeological artefacts. In this work, we have used it to analyse 216 out of the 5000 Merovingian glass beads that come from the necropolis of Bossut-Gottechain (Belgium), one of the most important ever found in Belgium. The IBA analyses confirmed the typological division of different beads groups through chemical composition that gives us new insights on fabrication techniques of glass matrices and colorants.

    Full Text Available BACKGROUND: Proteomic approaches based on mass spectrometry have been recently used in archaeological and art researches, generating promising results for protein identification. Little information is known about eastward spread and eastern limits of prehistoric milking in eastern Eurasia. METHODOLOGY/PRINCIPAL FINDING: In this paper, an ancient visible food remain from Subeixi Cemeteries (cal. 500 to 300 years BC of the Turpan Basin in Xinjiang, China, preliminarily determined containing 0.432 mg/kg cattle casein with ELISA, was analyzed by using an improved method based on liquid chromatography (LC coupled with MALDI-TOF/TOF-MS to further identify protein origin. The specific sequence of bovine casein and the homology sequence of goat/sheep casein were identified. CONCLUSIONS/SIGNIFICANCE: The existence of milk component in ancient food implies goat/sheep and cattle milking in ancient Subeixi region, the furthest eastern location of prehistoric milking in the Old World up to date. It is envisioned that this work provides a new approach for ancient residue analysis and other archaeometry field.

    The phase composition and the microstructure of four ferrous Japanese arrows of the Edo period (17th-19th century) has been determined through two complementary neutron techniques: Position-sensitive wavelength-resolved neutron transmission analysis (PS-WRNTA) and time-of-flight neutron diffraction (ToF-ND). Standard ToF-ND technique has been applied by using the INES diffractometer at the ISIS pulsed neutron source in the UK, while the innovative PS-WRNTA one has been performed at the J-PARC neutron source on the BL-10 NOBORU beam line using the high spatial high time resolution neutron imaging detector. With ToF-ND we were able to reach information about the quantitative distribution of the metal and non-metal phases, the texture level, the strain level and the domain size of each of the samples, which are important parameters to gain knowledge about the technological level of the Japanese weapon. Starting from this base of data, the more complex PS-WRNTA has been applied to the same samples. This experimental technique exploits the presence of the so-called Bragg edges, in the time-of-flight spectrum of neutrons transmitted through crystalline materials, to map the microstructural properties of samples. The two techniques are non-invasive and can be easily applied to archaeometry for an accurate microstructure mapping of metal and ceramic artifacts.

    One of the most frequently recurring questions in Archaeometry concerns the age of the studied objects. The some first dating methods were based in historical narrations, style of buildings manufacture techniques. However, has been observed that as consequence the continuous irradiation from naturally occurring radioisotopes and from cosmic rays some materials, such as archaeological ceramic, accumulate certain quantity of energy. These types of material can, in principle, be dated through the analysis of these accumulate energy. In that case, ceramic dating can be realized by thermoluminescence (TL) dating. In this work, results obtained by our research group about TL dating of ceramic belonging to several archaeological zones like to Edzna (Campeche), Calixtlahuaca and Teotenango (Mexico State) and Hervideros (Durango) are presented. The analysis was realized using the fine grained mode in a Daybreak model 1100 reader TL system. The radioisotopes that contribute in the accumulate annual dose in ceramic samples ({sup 40} K, {sup 238} U, {sup 232} Th) were determined by means of techniques such as Energy Dispersive X-ray Spectroscopy (EDS) and Neutron Activation Analysis (AAN). Our results are agree with results obtained through other methods. (Author) 7 refs., 2 tabs., 5 figs.

    Photon induced energy dispersive X-ray fluorescence (EDXRF) analysis is a valuable technique for the study of works of art, because it is nondestructive, multielemental, simple and relatively inexpensive. For this reason EDXRF is a very popular analytical technique in archaeometry. Portability of EDXRF equipments is extremely useful and almost mandatory in many cases, such as analysis of frescoes, of large paintings, bronzes, brasses and gold alloys, and so on, especially when located in museums. EDXRF analysis generally involves an area of a few mm{sup 2}, and a thickness between {mu}m and fractions of mm and, therefore, the analysis is superficial and dependent on the surface conditions. The frescoes by Giotto in the 'Chapel of the Scrovegni' in Padua were systematically analysed in the period July 2001-March 2002 in more than 300 points, before, during and after restoration, in order to detect the possible presence of superficial sulphur and to test various sulphur cleaning procedures. Further all pigments were systematically analysed in order to determine their composition. Golden haloes were also analysed and different pigment layers were detected under the gold leaf; from the EDXRF analysis the attribution of chemical elements to the proper layer was possible.

    This paper describes the new external microbeam on the 15 deg. beamline of the 5 MV Tandetron accelerator recently installed at the CMAM in Madrid. The focusing and beam extraction system was supplied by Oxford Microbeams Ltd. and consists of a high precision quadrupole doublet with an interchangeable Kapton window exit nozzle and front-viewing video microscope. The sample is positioned in the beam using a stepper motor stage. The beam current and beam profile have been determined under different experimental conditions. A simple method based on the signal processing of ion-induced luminescence from quartz targets has been used to determine the beam profile in two dimensions simultaneously, without scanning. This is the first step in the development of a real time beam profile monitoring system, which could be used as part of an automated beam focusing procedure. The beam line will be primarily devoted to archaeometry and cultural heritage studies. As an example we report the characterisation of two Tang appearance antique porcelains.

    Proton induced X-ray emission and Rutherford backscattering spectrometry are the most often used IBA methods in conjunction with a nuclear microprobe. Their main advantages derive both from the corresponding cross sections having relatively high values and their multielemental response. {mu}PIXE allows one to reach the spatial distribution of elements with Z>12 and {mu}RBS permits the study of multilayered solids with a good selectivity for thin heavy element layers deposited on light substrates. Nuclear reactions on the other hand generally exhibit low cross section values but are well adapted for light element isotope measurements in any substrate. This paper intends to provide an overview of nuclear reaction spectrometry analytical capabilities using {sup 1}H, {sup 2}H, {sup 3}He or {sup 4}He microbeams. Practical performances such as selectivity, sensitivity, total analysable depth and depth resolution are discussed. Finally, application examples are presented in the following areas: metallurgy and material sciences, earth sciences and cosmochemistry, biochemistry and archaeometry.

    In February 1998, almost 10 years ago, the set-up of the first IBA (ion beam analysis) facility in Spain took place with the arrival of a 3 MV tandem accelerator [J. Garcia-Lopez, F.J. Ager, M. Barbadillo-Rank, F.J. Madrigal, M.A. Ontalba, M.A. Respaldiza, M.D. Ynsa, Nucl. Instr. and Meth. B 161-163 (2000) 1137]. Since then, an intensive research program using IBA techniques has been carried out. Subsequently, a cyclotron for 18 MeV protons has been also installed at the 'Centro Nacional de Aceleradores' (CNA), devoted mainly to isotope production for PET (positron emission tomography) techniques, but possibly applied to material analysis and damage studies on a dedicated beam line. Moreover, a 1 MV tandem has been recently installed for AMS (accelerator mass spectrometry) {sup 14}C dating and environmental research with other isotopes. In the present paper we describe the new facilities and the developments of the 3 MV tandem beam lines occurred during the past years, as well as some examples of the most recent research activities in our Center in the fields of Material Science, Archaeometry, Biomedicine and Environment.

    Ceramic is the oldest synthetic material created by the mankind and has been present in human societies from around ten thousand years ago. During the last few decades, within the research field of Archaeometry, the study of archaeological and historical ceramic materials has experienced a significant increase in the application of chemical-physical techniques to obtain information on technology and production of these materials in the past. This paper presents the results obtained in a biblio metric study undertaken on 589 articles published on this subject in JCR journals and conference proceedings during the last decade (2000-2010). The main purpose of this research was to address the recent evolution and trends of this kind of investigations. The parameters analyzed were: date of publication, type of journal, topic, cultural-chronological classification of materials studied, origin country of authors, and analytical techniques used. Resulting data indicated a continual, stable, and growing publication rate on the subject in journals and conference proceedings of the three JCR indexes, namely SCI, AHCI, and SSCI, which evidences a high level of interdisciplinary. Authors from Europe and the United States carried out the majority of contributions. (Author) 30 refs.

    Full Text Available The excavation works being carried out since 1989 at Dorylaion (Eskişehir/Turkey results in many findings belonging to different civilizations spanning from the First Bronze age to Ottoman period. One of the important groups of these findings is the moldmade bowls, familiarly known as the Megarian bowls from the Hellenistic period (330-30 B.C.. In a frame of an archaeometry project work, these artifacts were characterized with different analytical techniques. Wavelength dispersive X-ray fluorescence (WDXRF and X-ray diffraction (XRD were used to study chemical and mineralogical composition of the bodies. Thermogravimetric-differential thermal analyses (TG-DTA were performed to make the estimation of firing temperature of the sherds. Scanning electron microscopy (SEM and energy dispersive X-ray spectrometry (EDX were performed for the microstructural and microchemical characterization of body and slip layers of the selected potsherds. Based on the analyses results, the bowls should have been prepared from carbonated and siliceous clays and fired at the temperatures from 600 to 1000 °C. They have also iron-rich slip layers with different colors indicating probable adjustment of the redox conditions during firing. In addition, the effect of maximum firing temperature on microstructural characteristics was evaluated.

    Archaeometry is a consolidated field with a wide application of nuclear analytical techniques for the characterization, protection, and restoration of archaeological pieces. This project aimed at studying the elementary chemical composition of 70 ceramic fragments samples from Sao Paulo II archaeological site, located along the Solimoes River channel, next to Coari city, in Brazilian Amazon. The characterization of samples was performed by neutron activation analysis (NAA). By the determination of 24 elements in the ceramic fragments ( Ce, Co, Cr, Cs, Eu, Fe, Hf, K, La, Lu, Na, Nd, Sb, Sm. Rb, Se, Ta, Tb, Th, U, Yb and Zn), it was possible to define groups of samples regarding the similarity/dissimilarity in elementary chemical composition. For such a task, the multivariate statistical methods employed were cluster analysis (C A), principal component analysis (PCA) and discriminant analysis (DA). Afterwards, seven ceramic fragments were selected based on the groups previously established, for the characterization of the site temporal horizon. Those ceramic fragments were analyzed by thermoluminescence (TL) and EPR for dating purposes. The firing temperatures were determined by electron paramagnetic resonance (EPR) technique, in order to infer about some aspects of the ceramic manufacture employed by the ancient peoples that lived in Sao Paulo 11. By the results obtained in this study, it was possible to identify the quantity of clay sources employed by the ceramists and the age of the ceramic pieces. Therefore, the results of this research may contribute to the study on the occupation dynamics in the pre-colonial Brazilian Amazon. (author)

    Neutron scattering techniques are attracting an increasing interest from scientists in various research fields, ranging from physics and chemistry to biology and archaeometry. The success of these neutron scattering applications is stimulated by the development of higher performance instrumentation. The development of new techniques and concepts, including radiative capture based neutron detection, is therefore a key issue to be addressed. Radiative capture based neutron detectors utilize the emission of prompt gamma rays after neutron absorption in a suitable isotope and the detection of those gammas by a photon counter. They can be used as simple counters in the thermal region and (simultaneously) as energy selector and counters for neutrons in the eV energy region. Several years of extensive development have made eV neutron spectrometers operating in the so-called resonance detector spectrometer (RDS) configuration outperform their conventional counterparts. In fact, the VESUVIO spectrometer, a flagship instrument at ISIS serving a continuous user programme for eV inelastic neutron spectroscopy measurements, is operating in the RDS configuration since 2007. In this review, we discuss the physical mechanism underlying the RDS configuration and the development of associated instrumentation. A few successful neutron scattering experiments that utilize the radiative capture counting techniques will be presented together with the potential of this technique for thermal neutron diffraction measurements. We also outline possible improvements and future perspectives for radiative capture based neutron detectors in neutron scattering application at pulsed neutron sources.

  18. Adaptation of Industrial Hyperspectral Line Scanner for Archaeological Applications

    The spectral characteristic of the visible light reflected from any of archaeological artefact is the result of the interaction of its surface illuminated by incident light. Every particular surface depends on what material it is made of and/or which layers put on it has its spectral signature. Recent archaeometry recognises this information as very valuable data to extend present documentation of artefacts and as a new source for scientific exploration. However, the problem is having an appropriate hyperspectral imaging system available and adopted for applications in archaeology. In this paper, we present the new construction of the hyperspectral imaging system, made of industrial hyperspectral line scanner ImSpector V9 and CCD-sensor PixelView. The hyperspectral line scanner is calibrated geometrically, and hyperspectral data are geocoded and converted to the hyperspectral cube. The system abilities are evaluated for various archaeological artefacts made of different materials. Our experience in applications, visualisations, and interpretations of collected hyperspectral data are explored and presented.

    Ionoluminescence (IL) has mainly been used to detect impurities or defects inside synthetic materials. This paper gives a summary of new applications of IL to natural minerals that might be found in ancient pieces of jewellery or decorative artefacts (affreschi, stucchi, mosaics). Some relevant examples of its use for archaeometrical purposes are given to highlight the potential of the technique. Chemical information can be obtained by luminescent characterization of minerals. IL spectra act as digital imprint for elements or defects inside each material, enabling differentiation of natural specimens from imitations and/or synthetic analogues. Crystal field theory indicates it is the coordination number of the emitter inside the crystalline structure that gives information on its valence. Historical confusion between rubies and red spinel can easily be resolved by analysis of IL spectra. Modern synthetic diamonds can also be discriminated and blue sapphire can be distinguished from blue kyanite, a silicate that is currently being sold as its imitation. The technique can also differentiate between the synthetic and the natural gems. Polymorphs can be identified, and it is possible to recognize minerals from isomorphic series (from the same chemical group with the same structure) even when they share the same light emitter (e.g. Mn(2+), in carbonates). High-quality glasses (e.g. laser glasses) which are normally used for faking gemstones can be also detected. We fully believe IL will, in the future, be a powerful technique for determining the crystallinity of solids. This paper gives an overview of possible applications of IL to archaeometry for mineral characterization; this is a new application that still requires further study.

    The evolution of metallurgy in history is one of the most interesting topics in Archaeometry. The production of steel and its forging methods to make tools and weapons are topics of great interest in the field of the history of metallurgy. In the production of weapons, we find almost always the highest level of technology. These were generally produced by skilled craftsmen who used the best quality materials available. Indian swords are an outstanding example in this field and one of the most interesting classes of objects for the study of the evolution of metallurgy. This work presents the study of a Shamsheer (a sword with a curved blade with single edge) made available by the Wallace Collection in London. The purpose of this study was to determine the composition, the microstructure, the level and the direction of residual strain and their distribution in the blade. We have used two different approaches: the classical one (metallography) and a nondestructive technique (neutron diffraction): In this way, we can test differences and complementarities of these two techniques. To obtain a good characterization of artifacts studied by traditional analytical methods, an invasive approach is required. However, the most ancient objects are scarce in number, and the most interesting ones are usually in an excellent state of conservation, so it is unthinkable to apply techniques with a destructive approach. The analysis of blades that has been performed by metallographic microscopy has demonstrated the specificity of the production of this type of steel. However, metallographic analysis can give only limited information about the structural characteristics of these artifacts of high quality, and it is limited to the sampled areas. The best approach for nondestructive analysis is therefore to use neutron techniques.

  2. On the dose-rate estimate of carbonate-rich sediments for trapped charge dating

    In a wide range of environmental conditions sediments are subject to changing water content and carbonate cementation during burial. Trapped charge dating of these carbonate-rich deposits requires the determination of a dose rate which is not constant during burial because sediments were subject to post-depositional geochemical alterations. The dose-rate model established in this study assumes linear increase of carbonate mass and linear decrease of water mass in pores between sediment particles during burial. Numerical modelling assesses the effect of carbonate and water on the infinite-matrix dose rate as a function of time. Sensitivity testing of the system indicated that water and carbonate content have the greatest effect on the resulting dose rate, followed by the timing of onset and completion of carbonate formation. As a consequence, a comprehensive re-calculation of the water correction factors was undertaken. It revealed a 5% lower value for the annual beta dose and a 10% lower value for the annual gamma dose compared to values formulated by Zimmerman [1971. Thermoluminescence dating using fine grains from pottery. Archaeometry 13, 29-52]. The dose-rate model was tested using samples from geologically well-constrained coastal sites. The differences between onset and final dose rate were up to 30% resulting in differences between modelled and conventional optical ages between 2% and 15% depending on the final (today's) water and carbonate content. The divergence of dates may be greater under certain conditions. The dose-rate model can be applied to a wide range of contexts similar to those considered in this case study.

    This paper presents a μ-XRF analytical approach for a non-destructive study of Cultural Heritage glass finds. This technique can be used for quantitative analysis of small volumes of solid samples, with a sensitivity that is superior to the electron microprobe but inferior to an ICP-MS system. An experimental set-up with natural and synthetic glass standards is proposed here for the quantitative analyses of major and trace elements on glass objects which cannot be sampled such as small archaeological or historical artefacts from Cultural Heritage. The described method, performed by means of the commercial μ-XRF Eagle III-XPL, was applied to Islamic glass specimens of Sasanian production (III-VII century A.D.) previously analyzed by ICP-MS and SEM-EDS techniques (P. Mirti, M. Pace, M. Negro Ponzi and M. Aceto, Archaeometry, 2008, 50(3), 429-450; P. Mirti, M. Pace, M. Malandrino and M. Negro Ponzi, J. Archaeol. Sci., 36, 1061-1069; and M. Gulmini, M. Pace, G. Ivaldi, M. Negro Ponzi and P. Mirti, J. Non-Cryst. Solids, 2009, 355, 1613-1621) and coming from the archaeological site of Veh Ardasir in modern Iraq. Major elements (Na, Mg, Al, Si, K, Ca, Fe) of glass specimens show an accuracy better than 5%. Trace elements (Cr, Mn, Sr and Zr) display an accuracy better than 5% when the checked elements have a concentration >100 ppm by weight, whereas it is around 10% with a concentration <100 ppm by weight. μ-XRF is, therefore, a suitable elemental analysis technique for the non-destructive study of small glass finds due to its relatively good accuracy, reproducibility and low detection limits (∼tens ppm).

    The Life Sciences Division (LSD) of Oak Ridge National Laboratory (ORNL) has a long record of radiation dosimetry research at the Dosimetry Applications Research (DOSAR) facility complex. These facilities have been used by a broad segment of the research community to perform a variety of experiments in areas including, but not limited to, radiobiology, radiation dosimeter and instrumentation development and calibration, and materials testing in a variety of radiation environments. Collaborations with the University of Tennessee-Knoxville (UTK) have also led to important contributions in the area of archaeometry, particularly as it relates to the use of radiation dosimetry to date archaeological artifacts. This manual is to serve as the primary instruction and operation manual for dosimetric and archaeometric research at DOSAR involving thermoluminescence (TL) and optically stimulated luminescence (OSL). Its purpose is to (1) provide protocols for common practices associated with the research, (2) outline the relevant organizational structure, (3) identify the Quality Assurance plan, and (4) describe all the procedures, operations, and responsibilities for safe and proper operation of associated equipment. Each person who performs research at DOSAR using TL/OSL equipment is required to read the latest revision of this manual and be familiar with its contents, and to sign and date the manual's master copy indicating that the manual has been read and understood. The TL/OSL Experimenter is also required to sign the manual after each revision to signify that the changes are understood. Each individual is responsible for completely understanding the proper operation of the TL/OSL equipment used and for following the guidance contained within this manual. The instructions, protocols, and operating procedures in this manual do not replace, supersede, or alter the hazard mitigation controls identified in the Research Safety Summary (&apos

  8. A revised burial dose estimation procedure for optical dating of youngand modern-age sediments

    The presence of genuinely zero-age or near-zero-age grains in modern-age and very young samples poses a problem for many existing burial dose estimation procedures used in optical (optically stimulated luminescence, OSL) dating. This difficulty currently necessitates consideration of relatively simplistic and statistically inferior age models. In this study, we investigate the potential for using modified versions of the statistical age models of Galbraith et??al. [Galbraith, R.F., Roberts, R.G., Laslett, G.M., Yoshida, H., Olley, J.M., 1999. Optical dating of single and multiple grains of quartz from Jinmium rock shelter, northern Australia: Part I, experimental design and statistical models. Archaeometry 41, 339-364.] to provide reliable equivalent dose (De) estimates for young and modern-age samples that display negative, zero or near-zero De estimates. For this purpose, we have revised the original versions of the central and minimum age models, which are based on log-transformed De values, so that they can be applied to un-logged De estimates and their associated absolute standard errors. The suitability of these 'un-logged' age models is tested using a series of known-age fluvial samples deposited within two arroyo systems from the American Southwest. The un-logged age models provide accurate burial doses and final OSL ages for roughly three-quarters of the total number of samples considered in this study. Sensitivity tests reveal that the un-logged versions of the central and minimum age models are capable of producing accurate burial dose estimates for modern-age and very young (<350??yr) fluvial samples that contain (i) more than 20% of well-bleached grains in their De distributions, or (ii) smaller sub-populations of well-bleached grains for which the De values are known with high precision. Our results indicate that the original (log-transformed) versions of the central and minimum age models are still preferable for most routine dating applications

    Luis Barba Laboratorio de Prospección Arqueológica Instituto de Investigaciones Antropológicas Universidad Nacional Autonoma de México The first magnetic survey in archaeological prospection was published in 1958 in the first number of Archaeometry, in Oxford. That article marked the beginning of this applications to archaeology. After that, magnetic field measurements have become one of the most important and popular prospection tools. Its most outstanding characteristic is the speed of survey that allows to cover large areas in short time. As a consequence, it is usually the first approach to study a buried archaeological site. The first attempts in Mexico were carried out in 196. Castillo and Urrutia, among other geophysical techniques, used a magnetometer to study the northern part of the main plaza, zocalo, in Mexico City to locate some stone Aztec sculptures. About the same time Morrison et al. in La Venta pyramid used a magnetometer to measure total magnetic field trying to find a substructure. Some years later Brainer and Coe made a magnetic survey to locate large stone Olmec heads in San Lorenzo Tenochtitlan, Veracruz. Technology development has provided everyday more portable and accurate instruments to measure the magnetic field. The first total magnetic field proton magnetometers were followed by differential magnetometers and more recently gradiometers. Presently, multiple sensor magnetometers are widely used in European archaeology. The trend has been to remove the environmental and modern interference and to make more sensitive the instruments to the superficial anomalies related to most of the archaeological sites. There is a close relationship between the geology of the region and the way magnetometry works in archaeological sites. Archaeological prospection in Europe usually needs very sensitive instruments to detect slight magnetic contrast of ditches in old sediments. In contrast, volcanic conditions in Mexico produce large magnetic contrast

    Stable isotope analysis of biogenic tissues such as tooth enamel and bone mineral has become a well recognized and increasingly important method for determining provenance of human remains, and has been used successfully in bioarchaeological studies as well as forensic investigations (Lee-Thorp, 2008; Meier-Augenstein and Fraser, 2008). Particularly, 18O and 2H stable isotopes are well established proxies as environmental indicators of climate (temperature) and source water and are therefore considered as indicators of geographic life trajectories of animals and humans (Hobson et al., 2004; Schwarcz and Walker, 2006). While methodology for 2H analysis of human hair, fingernails, and bone collagen is currently used to determine geographic origin and identify possible migration patterns, studies involving the analysis of 2H in tooth enamel appear to be nonexistent in the scientific literature. The apparent lack of research in this area is believed to have two main reasons. (1) Compared to the mineral calcium hydroxylapatite Ca10(PO4)6(OH)2, in tooth enamel forming bio-apatite carbonate ions replace some of the hydroxyl ions at a rate of one CO32 replacing two OH, yet published figures for the degree of substitution vary (Wopenka and Pasteris, 2005). (2) Most probably due to the aforementioned no published protocols exist for sample preparation and analytical method to obtain δ2H-values from the hydroxyl fraction of tooth enamel. This dilemma has been addressed through a pilot study to establish feasibility of 2H stable isotope analysis of ground tooth enamel by continuous-flow isotope ratio mass spectrometry (IRMS) coupled on-line to a high-temperature conversion elemental analyzer (TC/EA). An array of archaeological and modern teeth has been analyzed under different experimental conditions, and results from this pilot study are being presented. References: Lee-Thorp, J.A.

    Thermoelectrically cooled semiconductor detectors, such as Si-PIN, Si-drift, Cd1-xZnxTe and HgI 2, coupled to miniaturized low-power X-ray tubes, are well suited in portable systems for energy-dispersive X-ray fluorescence (EDXRF), analysis of archaeological samples. The Si-PIN detector is characterized by a thickness of about 300 μm, an area of about 2×3 mm 2, an energy resolution of about 200-250 eV at 5.9 keV and an entrance window of 25-75 μm. The Si-drift detector has approximately the same area and thickness, but an energy resolution of 155 eV at 5.9 keV. The efficiency of these detectors is around 100% from 4 to 10 keV, and then decreases versus energy, reaching ˜9% at 30 keV. Coupled to a miniaturized 10 kV, 0.1 mA, Ca-anode or to a miniaturized 30 kV, 0.1 mA, W-anode X-ray tubes, portable systems can be constructed, which are able to analyse K-lines of elements up to about silver, and L-lines of heavy elements. The Cd 1- xZn xTe detector has an area of 4 mm 2 and a thickness of 3 mm. It has an energy resolution of about 300 eV at 5.9 keV, and an efficiency of 100% over the whole range of X-rays. Finally the HgI 2 detector has an efficiency of about 100% in the whole range of X-rays, and an energy resolution of about 200 eV at 5.9 keV. Coupled to a small 50-60 kV, 1 mA, W-anode X-ray tube, portable systems can be constructed, for the analysis of practically all elements. These systems were applied to analysis in the field of archaeometry and in all applications for which portable systems are needed or at least useful (for example X-ray transmission measurements, X-ray microtomography and so on). Results of in-field use of these detectors and a comparison among these room temperature detectors in relation to concrete applications are presented. More specifically, concerning EDXRF analysis, ancient gold samples were analysed in Rome, in Mexico City and in Milan, ancient bronzes in Sassari, in Bologna, in Chieti and in Naples, and sulfur (due to pollution

    Full Text Available The author makes a summary on the situation of Building Archaeology in Italy from the 1990s onwards, when the creation of the journal “Archeologia dell’architettura” and several Congresses made it possible for different groups of investigators to share their strategies and experience, both regarding stratigraphic readings and their relationship to restoration and the study of buildings techniques, dimensional chronology and archaeometry. A key argument in this debate has been the application of this set of methods to architectural restoration, and experimentation on the static equilibrium sequence, degradation and wall coating as crucial instruments in a correct restoration process. This debate has given lesser focus to the main goal of the archaeologist: to obtain historical information from stratigraphic reconstructions, for which becomes in turn necessary to prepare repertoires and undertake extensive studies, relate archaeology to agrarian structures and landscape transformations as well as with social and economic structures. Archaeologists must work on this issue on the following years, without leaving aside the intimate relationship established with architectural restoration, to preserve the building patrimony in a context which should promote cultural multicentralism, the exchange of ideas and a recovery of civil society.Il contributo delinea un bilancio dell'Archeologia dell'architettura in Italia a partire dalla metà degli anni '90 del XX secolo, quando alcuni convegni e la neonata rivista "Archeologia dell'Architettura", misero a confronto le esperienze maturate in più centri di ricerca, che riguardavano non solo l’analisi stratigrafica delle murature il suo rapporto con il Restauro, ma anche allo studio delle tecniche costruttive, della mensiocronologia e dell’archeometria. Da questo punto di vista sono da segnalare da un lato le sperimentazioni nella costruzione delle sequenze degli equilibri statici, del degrado, degli

    Full Text Available By the beginning of the 1990s, critical readings on late antiquity and early medieval Spanish architecture put into relief avowed contradictions in the generally accepted theories about its genesis and evolution.This crisis suggested me the need to propose a new explanatory model, according to which the architectural revolution brought about by Visigoth architecture would have taken place through the contribution of the new Islamic culture, way into the Middle Ages. This approach prompted me to apply myself to Building Archaeology in order to turn it to the resolution of the problem. A decade after that proposal I intend to present my experience on the usefulness and limitations of Building Archaeology. It has in fact proved useful in order to ensure a renewal of the research interest on this architecture and to obtain a new corpus of data on a more rigorous basis, but it has not been enough to solve the problem in a definite way since, as each and every historical problem, it remains partly open and subject to continued renewal. Using different examples, I will delve on the site/building relationship,wall stratigraphy (building sequence, stratigraphy and style, stratigraphy and intervention, stratigraphy and diagnose, typology and decoration, archaeometry, documentation and absolute chronology.A comienzos de los años -90, diversas lecturas críticas sobre la arquitectura tardoantigua y altomedieval hispánica evidenciaron supuestas contradicciones en la teoría consensuada sobre su génesis y evolución.

    It was with great pleasure that the Department of Nuclear and Theoretical Physics of the University of Pavia and the INFN (Istituto Nazionale di Fisica Nucleare) Structure of Pavia organised the XIX Nuclear Physics Divisional Conference of the European Physical Society, which was held in the historical buildings of the University of Pavia from 5-9 September 2005. The Conference was devoted to the discussion of the most recent experimental and theoretical achievements in the field of Nuclear Physics applications, as well as of the latest developments in technological tools related to Nuclear Physics research. The University of Pavia has a long tradition in Physics and in Applied Physics, being the site where Alessandro Volta developed his "pila", the precursor of the modern battery. This is the place where the first experiments with electricity were conducted and where the term "capacitance" used for capacitors was invented. Today the University hosts a Triga Mark II nuclear reactor, which is used by the Departments of the University of Pavia and by other Universities and private companies as well. Moreover, Pavia is the site selected for the construction of the CNAO complex "Centro Nazionale di Adroterapia Oncologica" (National Centre for Oncological Hadrontherapy), planned for 2005-2008 which represents a unique facility in Italy and will be among the first complexes of this type in Europe. The Conference has gathered together experts in various fields from different countries and has been the occasion to review the present status and to discuss the new emerging trends in Nuclear Physics and its applications to multidisciplinary researches and the development of new technologies. The following topics were treated: Nuclear Techniques in Medicine and Life Sciences (Cancer Therapy, new Imaging and Diagnostics Tools, Radioisotope production, Radiation Protection and Dosimetry).

    Full text: The preservation of cultural heritage has acquired increasing interest in the last decades and many scientific techniques have been employed to analyze paintings, manuscripts, ceramics, glasses, statues, coins and metal artifacts in order to solve problems related to restoration, conservation, dating and attribution of artworks. There is also an increasing trend for non-destructive investigations since most of the samples are unique and precious objects of art and archaeology. X-Ray fluorescence (XRF) is the most widely used investigative technique in the field of archaeometry, due to a number of favorable analytical characteristics, such as multielemental and non-destructive analysis, high sensitivity and applicability to a wide range of samples. In this work, XRF was used to analyze altars, sculptures and paintings in the Saint Anthony Convent (Rio de Janeiro, Brazil). The cornerstone of this convent was launched in 1608, by the Franciscan friars, and the construction of the church was finished in 1620. The Saint Anthony sculpture in the main altar is one of the few remaining pieces from the XVII century in Rio de Janeiro. The splendid Baroque carvings of the chapel, covered with integral gilding, in the national Portuguese style, dates from 1716 to 1719. The results obtained during the analyses have been used in the meticulous process of restoration, developed in the last two years, in order to recover the original splendour of this important piece of our cultural heritage. The analyses were carried out with an EDXRF portable system developed in the Nuclear Instrumentation Laboratory, consisting of an X-ray tube Oxford TF3005 with W anode, operating at 25 kV and 100 {mu}A, and a Si-PIN XR-100CR detector from Amptek. In each sample were obtained several spectra, with an acquisition time of 300 s and a beam collimation of 1.5 and 2 mm. The spectra were analyzed using the software QXAS-AXIL from IAEA.

    The provenance of ore minerals used in prehistoric and historic times for copper smelting and extraction is one of the basic questions that archaeologists pose to modern analytical archaeometry [1]. To aid metal provenancing studies, a database of fully characterized Alpine copper mineralisations is being developed as the fundamental reference frame for metal extraction and diffusion in the past. In the early stages of the project, some of the most well known copper deposits in the Western Alps were selected and compared with very different minerogenetic deposits from the French Queyras (Saint Veran) and the Ligurian Apennines (Libiola, Monte Loreto). The fully characterized samples were then analysed by ICP-QMS (inductively coupled plasma-quadrupolar mass spectrometry). The abundances of about 60 minor and trace elements, including most transition metals and chalcophile elements, and the rare earths were measured in all samples. Furthermore, the feasibility of the routine reliable measurement of the 65Cu/63Cu isotope ratio [2] and its eventual use as a possible ore tracer was tested. Multicollector ICP-Mass Spectrometry was used to determine precise Pb isotopic ratios (206Pb/204Pb, 207Pb/204Pb, 208Pb/204Pb) and is being used for 65Cu/63Cu ratios as well. Advanced strategies based on multivariate analysis were then used to discriminate the ore mineral provenance. Data were treated with the chemometric software "The Unscrambler Version 9.5" (CAMO AS, Trondheim, Norway). Data pre-treatment, PCA [3] and PLS-DA [4,5] models were performed as implemented in the software. The availability of such unprecedented and complete amount of data of Alpine copper deposits also yields information relevant for the geochemical and minerogenetic intepretation of the deposits themselves. Application of PCA and PLS-DA to the geochemical and isotopic database proved to be a very powerful tool to discriminate the ore source areas with very little ambiguity. The applications to

The proteomic method, which has become increasingly important internation- ally, has unique advantages in residue analysis. The Xiao - He graveyard in Lop Nur of Xinjiang province is dated back to 3500- 4000 years old. Brown granular residues are always found in excavated grass baskets. First, infrared spectros- copy was used to analyze one brown granular residue in a grass basket from tomb number 13. This technique revealed a high protein content. Then the residue was extracted and analyzed using proteomic methods. Bovine casein, bovine im- munoglobulin and bovine [3 -laetoglobulin were identified, which indicated the residues probably came from a milk prod- uct. It should be noted that this was the earliest evidence for a milk product in China and suggests that milk was an im- portant component of ancestors' diet in Xiao He. This study also showed that the proteomic method has high sensitivity, requiring only small amount of samples, and that it can be

    Full Text Available Research on mercury or fire gilding technology during Prehistory and Antiquity is at its beginnings due to the fact that its identification and characterization is completely dependent on analytical techniques, mainly non destructive Archaeometry techniques allowing an easy characterization of the archaeological objects. Actually we rely on a small number of analytical data, much more limited if we place ourselves within the Iberian peninsula or if we are concerned with the early stages of the use of this technology because... nobody finds what it is not looked for.
    We submit a summary of data anlyisis by XRF and PIXE in order to characterize two groups of items: on the one hand a special type of iberian brooch with animals and hunting scenes, made up of gilded silver, and on the other the visigothic treasure of Torredonjimeno, Jaén. From the debate on these results the hypothesis of a local origin for fire gilding technology during the iberian period, about 4th century B.C., has come out regardless other centers of possible inception in Europe or the Mediterranean. A final stage would be represented by visigothic jewellery that closes the late Antiquity technological domain system up.

    Full Text Available In recent years a field of research of growing interest has been the application of physico-chemical characterization methods on modern materials to the study of ancient materials found by the archaeologists. This new field on Materials Science is known as Archaeometry. Many questions about the origin and manufacture of ancient glasses can be solved by using the same methods of analysis and microstructure characterization applied normally to special and advanced glasses. The islands of Mallorca and Menorca, located in the Balearic archipelago in the Mediterranean sea, has long been a crossing place of cultures. Transparent, opal and coloured glasses have been found in various archaeological investigations carried out in these islands. In order to know the composition and microstructure of some of these glasses, an archaeometric study has been carried out using X-ray diffraction (XRD, transmission electron microscopy (TEM, scanning electron microscopy and energy-dispersive X-ray analysis (SEM/EDX, differential thermal analysis (DTA, and hot stage optical microscopy (HSM methods. The SEM/EDX average microanalysis results show that these glasses are deficient in sodium and highly enriched in Al2O3 and Fe2O3, their composition being in the range: 0.5-1.5 K2O, 8-10 CaO, 6-8 Al2O3, 6-8 Fe2O3, 74-76 SiO2 (wt%. Some of these glasses also contain high percentages of lead. Small quantities of TiO2, CuO and SO3 (0.5 % have also been detected. Surface decoration and blue colour are other features of these ancient glasses, the surface of which, depicted by SEM, is highly altered with flaked and corroded microstructures.

    En los últimos años la aplicación de los métodos físicoquímicos de caracterización de materiales modernos al estudio de materiales antiguos es un campo de investigación de creciente interés para
