The metagabbro-amphibolite sequences in the KTB pilot hole contain intercalations of talc-chlorite-amphibole felses (or ''hosbachites''), which show transitional contacts to the adjacent metagabbros. The hosbachites are characterized by relics of a primary igneous texture and still contain igneous minerals like clinopyroxene, biotite and pseudomorp...

Subordinate serpentinites in Moldanubian gneisses in northeastern Bavaria were formerly harzburgites to dunites. They contain relics of apparently primary chromite which are similar in composition to chromites in ophiolitic, Alpine-type tectonites as described in the literature and as studied at Brezovica and Raduša (Yugoslavia). The northeastern B...

... From petrological studies on talc-chlorite-amphibole felses or hoesbachites, it was inferred that these rocks are the result of complex metasomatic alteration of mafic to ultramafic cumulates under amphibolite-to greenschist-facies conditions (Matthes and Schubert 1967;Schubert 1969;Okrusch et al. 1995). Cumulates form by gravimetric differentiation of early crystals that sink to the bottom of a magma chamber (Hunter 1996). ...
