Fig. 5: Brittle faulting along major normal faults within Triassic Evaporites, TE.
From: Rock and fault rheology explain differences between on fault and distributed seismicity

a, b Large displacement (hundreds of meters) normal faults with brittle deformation, characterized by grain-size reduction and localization along principal slipping surfaces, PSS. The dashed yellow line marks the fault parallel foliation within the gypsum-anhydrites rocks.
