Late orogenic carboniferous extensions in the Variscan French Massif Central
The Variscan French Massif Central experienced two successive stages of extension from Middle Carboniferous to Early Permian. In the northern Massif Central, the first stage began in the late Visean, immediately after nappe stacking, and is well recorded by NamurianWestphalian synkinematic plutonism. The Middle Carboniferous leucogranites widespread in the NW Massif Central (Limousin and Sioule...
متن کاملA review of the pre-Permian geology of the Variscan French Massif Central
The Massif Central, like the southern part of the Massif Armoricain, belongs to the North Gondwana margin. The Massif Central consists of a stack of nappes resulting of six main tectonicmetamorphic events. The first one, D0, is coeval with an Early Late Silurian (ca 415 Ma) highpressure (or ultra high-pressure) metamorphism for which the associated structures are poorly documented. The Early De...
متن کاملGravity Inversion, Ams and Geochronological Investigations of Syntectonic Granitic Plutons in the Southern Part of the Variscan French Massif Central
Magnetic fabric analyses, gravity inversion associated with chemical U-Th-Pb dating and structural observations are carried out to elucidate relationships between faulting and magmatic processes. This multidisciplinary study has been undertaken on Late Carboniferous plutons, situated in the southern part of the Variscan French Massif Central (FMC). The Glénat, Omps and Boisset plutons crop out ...
متن کاملThree-dimensional shape and emplacement of the Cardenchosa deformed pluton (Variscan Orogen, southwestern Iberian Massif)
The Cardenchosa pluton is a Lower Carboniferous Variscan granite located in the southwestern Iberian Massif. It intruded along the contact between the Sierra Albarrana and Azuaga tectonic units. To the northwest the pluton connects with the leftlateral Azuaga fault. The pluton appears in the footwall of the low-angle normal Casa del Cafe fault, which crops out to the west of the granite. Gravi...
متن کاملUraninite, Coffinite and Brannerite from Shear-Zone Hosted Uranium Deposits of the Bohemian Massif (Central European Variscan Belt)
New mineralogical data are presented for shear-zone hosted uranium mineralisation from selected uranium deposits that occur in the Bohemian Massif. The uranium mineralisation is in high-grade metamorphic rocks of the Moldanubian Zone and/or in granitic rocks of the Moldanubian batholith and Bor pluton as complex uraninite–coffinite and uraninite–coffinite–brannerite assemblages. For analysed co...
