S.15: Es handelt sich um einen Biotit-Streifengneis, dessen Planartextur durch abwechselnde Biotit-reiche Streifen (Länge bis 10 cm, Breite 0.1-1 cm) und leukokrate Lagen/Streifen (Länge 5-20 cm, Breite 2-10 mm) definiert wird. Trotz dieser weitständigen räumlichen Ordnung ist das Gestein feinkörnig, d.h. alle Domänen bestehen aus polykristallinen Aggregaten der betreffenden Minerale (Quarz, Plagioklas, Kalifeldspat, Biotit).
