Geological setting in the surroundings of the Wilhelminenstollen, including fault zones, as obtained from the geological mapping and remote sensing. Measurements of fracture geometries indicate several predominant strike directions with two peaks in NNE-SSE and NW–SE direction (see inlet). Inlet symmetric distribution statistics of orientation of joint strike directions (n = 127) in the Blauen granite around the Wilhelminenstollen display predominant NNE-and NW-striking joints and subordinate WSW- and WNW-striking joints
