Resolving the Variscan evolution of the Moldanubian sector of the Bohemian Massif: the significance of the Bavarian and the Moravo-Moldanubian tectonometamorphic phases

Another important feature of the Moravo-Moldanubian Phase was the subduction of crustal rocks to mantle depths (Carswell 1991; Becker and Altherr 1992; Kotková et al. 1997; O'Brien 2000; Vrána and Fryda 2003) and their subsequent rapid exhumation to middle and upper crustal levels (Gföhl Unit). The name "Bavarian Phase" has been chosen in appreciation of the early work of Fuchs (1962, 1976) and Thiele (1962), who have first recognized that in the western Austrian sector of the Bohemian Massif (Bavaricum after Fuchs 1976) an older fold belt (considered as "Caledonian" at that time) was penetratively overprinted by later anatectic and tectonic events.
