p.92: The Schiahorn Nappe (formerly “Arosa Dolomites”) is a small unit underlying the Silvretta Nappe between Tiefencastel and Davos. It consists of Triassic to Early Jurassic sediments with lithofacies similar to that of the Upper Austroalpine Ortler Nappe (see § 8.2.7; Furrer 1993, Eberli 1988, Froitzheim et al. 1994). In the Rätikon area (northeast corner of the Prättigau Half-Window), Nagel (2006) correlates the sedimentary “Southern Mittagspitz Zone” with the Schiahorn Nappe, both having a similar stratigraphic sequence with respect to the Allgäu Nappe, as well as a structurally comparable position with it.
