p.93: In contrast [to the S-charl-Unterbau], the “S-charl-Oberbau”, referred to as Tavrü Slice, straddling the northeastern rim of the S-charl-Sesvenna Nappe neighbouring the Engadine Fault (see § 10.5), consists entirely of a Norian to Cretaceous succession, volumetrically dominated by an over 2 km thick Hauptdolomit. The Tavrü Slice is completely detached from the Carnian Raibl Group. This slice, separated from the tectonically higher Ötztal Nappe by the Schlinig Thrust, suffered substantial internal extension in a domino-style (see cross-sections in Trümpy et al. 1997); the cause of this extension, either by stretching below the basal thrust of the Ötztal Nappe (Schmid & Haas 1989) or by deformation during the Late Cretaceous extensional phase (Froitzheim et al. 1997), being a matter of debate.
