Stereonets (equal-angle, lower-hemisphere projection) showing the faults mapped during the field survey in Verzi (FFV). The arrows indicate the trend and plunge of the slickenlines. A–D Stereonets showing the strike, dip, striae trend and plunge of the four main sets of measurements (FFV1, FFV2, FFV3, FFV4) and the standard deviations. The sense of slip can be normal (N), reverse (R), right-lateral (RL) or left-lateral (LL). Most sets represent NE-SW right-lateral faults and NW–SE left-lateral faults. E Stereonet showing P- and T- axes of all the measured faults. The white and grey areas represent the shortening and the extensional domains, respectively. The blue square represent the direction of the first principal strain axis (1, maximum shortening), the red square the third principal strain axis (3) and the yellow square the direction of the intermediate strain axis (2). F Stereonet showing the bedding in Verzi, with the mean value of its dip direction and dip
