p.67: Following OBERHOLZER (1955), the two slices of polycyclic gneisses were depicted on the present map but, due to the map scale, these two lithologically distinguished units were grouped into one single unit called the Goms Gneiss Complex. OBERHOLZER (1955) described two-mica plagioclase K-feldspar gneiss, migmatite (“Mischgneise”) and biotite-plagioclase gneiss derived from sedimentary protoliths intercalated with amphibolitic layers and a serpentinite lens. These rock associations are very similar to sequences in the “Streifengneis” Complex, Paradis Gneiss Complex and the Val Nalps Gneiss Complex of the adjacent Ausserbinn-Piz Cavel Zone of the Gotthard Nappe. Noteworthy is a strong alteration of the gneisses in the region of Ernen and an epidote- and chlorite-rich metagranodiorite (“Gneis von Unterwasser”, OBERHOLZER 1955).
