Cross section 4 running parallel to the traces of the fold axes from eastern Switzerland to the east of the Kleinwalser and Iller valleys (for the trace of the cross section, see Fig. 3). The structure west of the Rhine Valley is based on seismic data taken from Naef (2010). Note that small occurrences of Triassic rocks along the base of the Gonzen-Walenstadt imbricates at the very western end of the cross section cannot be ruled out. The easternmost part of the cross section is lighter colored as far as it was largely constructed using surface outcrops and measurements together with data from well Hindelang 1 (Huber and Schwerd 1995). The latter was projected to the SSW without any correction for depth. Scattered W dipping datasets were discounted in order to keep the image simple. Generally, thrust faults within Early to Middle Jurassic units and the Northalpine Foreland Basin sediments are not imaged. The Helvetic basal thrust and the Säntis thrust are highlighted. Scaling is in Meters
