These units com- prise Variscan orthogneisses (the Zentralgneise) and their host rocks, the “Pre-Zentralgneis-Complexes” (formerly “Altes Dach”).__ The “Pre-Zentralgneis-Complexes” comprise the “Zwischenelendschiefer” (biotite-schists, garnet-micaschists and sericite-schists) and amphibolites. Their contacts with the Zentralgneise are mostly concealed by debris- and rock flows or overprinted by shear zones and faults. Preserved primary contacts are rare. Characteristic of the biotite-schists are biotite-blasts of golden colour due to weathering. Besides this biotite, quartz, plagioclase, potassium feldspar, white mica, and chlorite also calcite, garnet, magnetite/ ilmenite, titanite, and zircon are present._________________________________________________________________________
