| Description
| - The felsic granulites with the Variscan (~340 Ma) HP?HT assemblage Grt+Qtz+hypersolvus Fsp+-Ky, correspond geochemically to slightly peraluminous, fractionated granitic rocks. U, Th and Cs are strongly depleted, probably because of the fluid and/or slight melt loss during the HP metamorphism (900?1050 C, 1?5?2?0 GPa). However, the rest of the trace-element contents and variation trends can be explained by fractional crystallisation of a granitic magma. Low Zr and LREE contents yield ~750 C Zrc and Mnz saturation temperatures and suggest relatively low-T crystallisation. The granulites contain radiogenic Sr (Sri=0?7106?0?7706) and unradiogenic Nd (EpsNdi=-4?2 to -7?5), indicating derivation from an old crustal source. The bulk of felsic granulites do not appear to represent separated, syn-metamorphic Variscan HP?HT melts. Instead, they are interpreted as metamorphosed (partly anatectic) equivalents of older, probably high-level granites subducted to continental roots during the Variscan collision.

- Variské felzické granulity Gföhlské jednotky moldanubika geochemicky odpovídají mírně peraluminickým, frakcionovaným granitům. Kromě silného ochuzení U, Th a Cs, což lze připsat na vrub ztrátě fluid při vysokotlaké metamorfóze, lze zastoupení většiny stopových prvků vysvětlit frakcionací granitového magmatu. Nízký obsah Zr a LREE ukazuje na saturační teploty zirkonu a monazitu kolem 750 C. Radiogenní Sr a neradiogenní Nd ukazuje na vznik ze starého korového zdroje. Celý komplex je interpretován jako metamorfované starší variské granity. (cs)
