Cross-cutting fault relationships. a Fault set (1) is cross-cut by (2), with the main slickenfibre direction on this plane indicated by thin black lines with arrowheads. Wildstrubelhütte, (602508/136659). For scale, a square bright compass can be seen immediately below the white arrow of fault set (1). b Schematic block diagram, showing the distinction between the three post-nappe oblique fault sets (1), (2) and (3). c Example of fault structure in the Rhône Valley (592461/120452) belonging to fault set (3). In black and white, main foliation of foot- and hanging wall, respectively; orange arrows mark the slickenfibre directions, giving top to the SW shear; the white arrow indicates the normal dip-slip component of displacement
