p.32: The 2nd phase Diablerets and Wildhorn thrusts cut across the older basal thrust of these “Ultrahelvetic” units (Jeanbourquin 1994, Steck et al. 2001, Pfiffner et al. 2010) in the same way as the out-of-sequence thrusts east of the Thunersee. Consequently, the units originated from the Helvetic platform and situated below the Diablerets and Wildhorn thrusts belong to the Lower Helvetic and those above these thrusts to the Upper Helvetic domain. As the Diablerets and Wildhorn thrusts have a significantly smaller displacement (10–15 km) compared to the Axen Thrust (20–25 km) and Glarus Thrust (30–35 km) in the east (Pfiffner 2011), not all the units of Ultrahelvetic origin are involved and thus cannot be allocated to either the Upper or Lower Helvetic. For this reason, they are all considered as Upper Helvetic west of the Thunersee and are included in the Pillon and Bulle mélange zones (see § 4.2.7 and 4.2.8).
