S.45: Untere Tufflage: Der als «Tuff-Basiszone» ausgeschiedene Horizont unterscheidet sich lithologisch vom hangenden Tuff. Bräunlich-rötlicher mergeliger Tuff, zum Teil Heliciden führend, relativ hoher Gehalt an Apatit, Magnetit und Hornblende. Mächtigkeit 0,1 – 0,7 m. Der im Rahmen der Kartierung unmittelbar im Liegenden der ersten Konglomeratbank neu entdeckte Deckentuffaufschluss entspricht der unteren Tufflage.
