From: Rock and fault rheology explain differences between on fault and distributed seismicity
a, b Foliated and folded gypsum/anhydrite rocks (white) with boudinaged dolostone (grey lenses highlighted by dashed yellow lines). The dashed green line marks the geometry of the folds. c Gneissic transposed fabric affected by normal faulting and boudinage of the dolostone layers. d Domino-like structure with brittle faulting on dolostones and ductile deformation on gypsum/anhydrite. e Small displacement (meters), gently dipping normal fault at the boundary between gypsum/anhydrite rocks. In the hangingwall dashed yellow lines mark the foliation within gypsum/anhydrite rocks whereas fractured dolostones are present in the footwall. f Intense subvertical hydrofracturing within the dolostones.
