Lithologies of the Modereck nappe system. a cargneule (Rauhwacke) of the Middle to Upper Triassic Seidlwinkl Formation. b isoclinal fold in carbonate quartzite from the Brennkogel Formation. Figures c to h show thin section images of lithologies of the Modereck nappe system (parallel polarizers in c, e and g and crossed polarizers in d, f and h: The dark micaschist of the Brennkogel Formation (c, d; sample PG149, 47.17763°N 12.81997°E) consists primarily of phengite, quartz, carbonate minerals (calcite, ankerite?) and carbonaceous matter, feldspar is very rare. The arkosic layers within the Bündnerschiefer-type 3 metasediments of the Trögereck Nappe (e, f; sample PG62, 47.08515°N 12.87452°E) mainly consist of abundant albite blasts (or clasts), phengite, carbonate minerals, quartz, carbonaceous matter and some epidote. The chloritoid-bearing phyllite of the Piffkar Formation (g, h; sample PG141, 47.13907°N 12.84402°E) comprises phengite, quartz, chloritoid, chlorite and Ti-rich phases (ilmenite, rutile)
