a Profile-like view of the Windgällen-Färnigen zone and structural data. Location is given in Fig. 3c. b Färnigen normal fault. Strongly foliated (highlighted as green lines) Cretaceous limestones and a \(\sim 10\,\text {cm}\) thick band of weakly deformed Nummulite-bearing Paleogene sandstone are directly adjacent to a fault breccia (black). The gneisses adjacent to the normal fault are overprinted by cataclasites indicating S-block down movement (highlighted as red lines) and are only weakly overprinted by younger Alpine deformation. The Färnigen normal fault dips \(70^{\circ }\) SSE (coordinates: \(46.7303^{\circ }\text {N}/8.4740^{\circ }\text {E}\)) c S3 overprinting an intense S0–S2 composite foliation (coordinates: \(46.7281^{\circ }\text {N}/8.4814^{\circ }\text {E}\)). d Well-developed stretching lineation in fine-grained limestone and pressure shadow around a pyrite concretion in the main foliation surface (S0–S3 composite, coordinates: \(46.7291^{\circ }\text {N}/8.4850^{\circ }\text {E}\)). e Overturned stratigraphic contacts between Carboniferous, Mesozoic sediments and the basement. The presence of dolomite clasts indicates a (Middle?) Jurassic or younger age for the basal conglomerate (Coordinates: 46.7269\(^{\circ }\text {N}/8.4830^{\circ }\text {E}\)). f Centimetre-sized shear band type fragmented quartz porphyroclast indicating top-to-the NNW shearing during D2 (coordinates: \(46.7269^{\circ }\text {N}/8.4830^{\circ }\text {E}\))
