Variscan orogeny in Bohemian Massif and French Massif Central: differences and similarities

Popis výsledku v původním jazyce

Following are main similarities and differences between the Bohemian Massif and the French Massif Central: Crustal-scale geometry and orogenic architecture: in the BM the lower crust is composed of 10 km thick felsic layer situated beneath a mafic one. The BM is a supra-subduction orogen of double crustal thickness mainly derived from the Upper plate, except for exhumed felsic orogenic lower crust, which comes from the Lower plate. In contrast, the current lower crust of the FMC consists of a layered mafic crust (gabbros, mafic granulites and minor felsic granulites) located beneath a stack of mainly felsic units. The FMC architecture is derived from both Upper and Lower plates. Subduction processes: in the BM these were marked by 60 m.y. lasting continuous SE-dipping subduction leading to the formation of blueschist-facies rocks with A, B and C-types of eclogites and significant arc magmatism. In contrast, the FMC reveals B-type eclogites and discontinuous arc magmatism related to a p
