What drives remelting of thickened continental crust in the Bohemian Massif?
Original language description
Following the crustal collision and the thermal peak of the regional metamorphism, the Moldanubian Zone was penetrated by voluminous anatectic plutons of the Moldanubian Plutonic Complex (MPC). The precise U?Pb Zrn and Mnz geochronology indicates that over its 80 % was constructed during the narrow time period of ~331?323 Ma (Gerdes et al., 2003), forming coarse-grained, Kfs-phyric Weinsberg granitoids (331?323 Ma) and porphyritic two-mica Eisgarn granites (328?326 Ma). Finally, small volumes of fine-grained I-type granites?granodiorites intruded at 319?300 Ma. Thus there seems to be a significant time gap between the mid-crustal emplacement of the hot granulite bodies with ultrapotassic plutons on the one hand, and widespread partial melting of the Moldanubian middle crust, in particular the Monotonous Group paragneisses, on the other. As the amount of basic magmas spatially associated with the Weinsberg and Eisgarn granitic suites is severely limited, ruled out is not only advection
