p.34: At the northeastern end of the Aar Massif, the crystalline basement dips to the NE below its sedimentary cover; it reappears as a small occurrence in the Vättis Window about 30 km further northeast. In this region, a late out-of-sequence thrusting involves the basement and cover of the Aar Massif as well as the overlying Blattengrat and Sardona nappes. The displacement along each of these thrust faults is approximately 1– 2 km (Fig. 5). These thrusts define post-nappe units; from bottom to top: the Kaminspitz, Stelli, Marchegghorn, Orglen, Calanda, Mirutta and Tschep slices (see Pfiffner 1978 for a review).
