Variscan subduction-related plutonism in the French Massif Central [PDF]

, 2022
The French Massif Central belongs to the Moldanubian Zone, which is an internal part of the Variscan Orogen. The Massif was formed during six tectonic-metamorphic events and has a nappe structure.

Flow of partially molten crust controlling construction, growth and collapse of the Variscan orogenic belt: the geologic record of the French Massif Central

BSGF - Earth Sciences Bulletin, 2020
We present here a tectonic-geodynamic model for the generation and flow of partially molten rocks and for magmatism during the Variscan orogenic evolution from the Silurian to the late Carboniferous based on a synthesis of geological data from the French

Petrogenetic link between metasedimentary rocks, migmatites and granitoids in the Variscan basement of the Pontgibaud area, French Massif Central – implications for the crustal structure

BSGF - Earth Sciences Bulletin
The architecture of the crust in the French Massif Central (FMC) is described as a nappe stack composed, from top to bottom, of the Upper Gneiss Unit (UGU), the Lower Gneiss Unit (LGU), and the Para-Autochthonous Unit (PAU), which are intruded by ...

Multistage development of a hydrothermal W deposit during the Variscan late-orogenic evolution: the Puy-les-Vignes breccia pipe (Massif Central, France)

BSGF - Earth Sciences Bulletin, 2021
The Puy-les-Vignes W deposit, located in the northwestern French Massif Central (FMC), is a rare occurrence of a wolframite-mineralized hydrothermal breccia pipe hosted in high-grade metamorphic gneisses.

Testing the Sensitivity of Anisotropy of Magnetic Susceptibility (AMS) to the Regional Tectonic Strain Field in Granite Plutons; Insights From Two Orogen-scale Studies

Tektonika
Anisotropy of Magnetic Susceptibility (AMS) fabrics within many individual granite plutons have previously been interpreted as recording the regional syn-magmatic tectonic strain field. To test this hypothesis, we compiled a regional database of AMS data
