Tectonic map of the St-Ursanne area, modified from Laubscher (1963a, b). Dip data are taken from Swisstopo (2012). The map overlies a hillshade model that illustrates the topography of the terrain (digital terrain model from Swisstopo 2011). Note the interplay between ENE and NNE-trending anticlinal axes, thrusts, and cross faults, and the intersection with both cross sections. A NNE-tending faults typically cut across and sinistrally offset anticlinal traces, B NNE-tending faults typically cut across and sinistrally offset anticlinal traces and C The La Caquerelle thrust and anticline offsetting the Clos du Doubs anticline and interfering to form the Mont Russelin culmination
