a Conjugate en-échelon vein system associated with sub-horizontal pressure-solution planes parallel to bedding. On the left there is an example of fault initiation. Weisshornlücke (602677/136443, 2820 m). b 3D sketch of oblique-normal ductile-brittle shear and faulting taking photo a) as an example. c 2D example of fault initiation and shearing of veins within conjugate ductile-brittle shear zones. As the viewing direction is near-perpendicular to strike, the apparent dip of bedding is sub-horizontal. Gemmipass (613477/138537)
