Název v původním jazyce

Lithological composition and geodynamic evolution of the south-eastern part of the Šumava Mts.(Moldanubian Zone, Bohemian Massif)

Popis výsledku v původním jazyce

The SE part of the Šumava Mts. (i.e. Bohemian Forest) offers a unique opportunity to observe the interaction of deformations in high-grade metamorphic rocks with development of magmatic fabrics in contemporaneous intrusions in a fluid state, proceeding at temperatures above ~700 °C and pressures corresponding to depths of ~20?30 km. The geological history is related to the Variscan orogenic processes, which, in this region of the so-called Moldanubian Zone, can be divided into (1) Exhumation of the deep-seated rocks at ~343?335 Ma associated with ascent of ultrapotassic, Mg-K-rich (durbachite) intrusions, immediately followed by an LP?HT metamorphic event and anatexis; (2) Intrusion of large volumes of high-K I-type Weinsberg granitoids into the partially exhumed Moldanubian rock syntectonic with distinct younger deformations at ~340?325 Ma, followed by emplacement of peraluminous S-type Eisgarn posttectonic granites contemporaneous with the activity of the Pfahl Shear Zone at ~325 Ma.
