p.89: In the southwestern part, between Tiefencastel and Arosa, the Lower Austroalpine is represented by two small nappes, namely from top to bottom: the Rothorn Nappe with a basement-cover sequence, directly underlying the Upper Austroalpine Schiahorn Nappe (see § 8.2.2), and the sedimentary Tschirpen Nappe overlying the Arosa Zone.
