S.6: Kärpf-Serie: Rein detritische Serie, wobei von unten nach oben die Komponentengröße rasch zunimmt und mit dem Gipfelkonglomerat endet. Bemerkenswert sind exotische Gerolle. In der Glarner-Decke, wo die der Serie f entsprechenden Ablagerungen viel mächtiger sind und wo sie den jüngsten Verrucano vertreten, gliedern wir diesen in die Abteilungen g—i.

p.133: In the Freiberg area, on the other hand, the top of the Karrenstock Formation, which is often composed of spilite or rhyolite, is truncated by an angular unconformity across which the angle between bedding planes can reach up to 10° (Schielly 1964, Nio 1972). The significance of this unconformity will be discussed below. Above this surface, the youngest Formation of the Glarus Verrucano in the Freiberg area, the Kärpf Formation (Schielly 1964, Nio 1972), follows. It is dominated by a coarse clastic body, the Kärpf Sernifite, which builds the prominent summit of the Kärpf mountain.
