U–Pb zircon and monazite geochronology of post-collisional hercynian granitoids from the Central Iberian Zone (Northern Portugal)

Dias, G.; Leterrier, J.; Mendes, Anabela Carreira; Simões, P. P.; Bertrand, J. M.

In the Central Iberian Zone (CIZ) of the Iberian Massif large volumes of granitoids were emplaced during the post-collisional stage of the Hercynian orogeny (syn- to post-D3, the last ductile deformation phase). Twelve granitic units and a quartz monzodiorite were selected for a U–Pb zircon and mona...

Middle Carboniferous crustal melting in the Variscan Belt: New insights from U-Th-Pbtot. monazite and U-Pb zircon ages of the Montagne Noire Axial Zone (southern French Massif Central)

Faure, Michel; Cocherie, Alain; Be Mezeme, Eugène; Charles, Nicolas; Rossi, Philippe

In France, the Devonian-Carboniferous Variscan orogeny developed at the expense of continental crust belonging to the northern margin of Gondwana. A Visean-Serpukhovian crustal melting has been recently documented in several massifs. However, in the Montagne Noire of the Variscan French Massif Centr...

Devonian geodynamic evolution of the Variscan Belt, insights from the French Massif Central and Massif Armoricain

Faure, Michel; Be Mezeme, Eugène; Cocherie, Alain; Rossi, Philippe; Chemenda, Alexandre; Boutelier, David

The Paleozoic French Variscan Belt in Massif Central and Massif Armoricain is a collision belt that provides a good example of a suture zone where ophiolites are rare, and the frontal (i.e., the magmatic arc) part of the upper plate is not present. In the lower plate (or Gondwana), the continental r...

A multidisciplinary study of a syntectonic pluton close to a major lithospheric-scale fault: relationships between the Montmarault granitic massif and the Sillon Houiller Fault in the Variscan French Massif Central. Part I: Geochronology, mineral fabrics and tectonic implications

Joly, Aurore; Chen, Yan; Faure, Michel; Martelet, Guillaume

Due to its location along one of the major faults, the Sillon Houiller Fault (SHF) of the French Massif Central (FMC), the Montmarault granitic pluton is well-suited to better understand the place of the late-orogenic magmatism in Variscan orogeny. Through a methodological approach, the close spatia...
