From: Veining and post-nappe transtensional faulting in the SW Helvetic Alps (Switzerland)
Fault zone core from the Tsa Bonna Fault (604094/132545, 2450 m). a From left to right, transition from undeformed bedrock into the fault zone. b Mylonitic foliation preserved on either side of the fault zone and as lenses in the cataclastic breccia. c Wildhorn Fault. Fault core structure with marly ductile units in the footwall and mylonitic to more brittle/cataclastic limestones, separated by a discrete late slip surface. d Thin section photograph of a reworked mylonite collected in the footwall of the Wildhorn Fault (697307/134298) with common pressure solution planes (dark levels), twinned calcite and gradually finer grain size of clasts toward the top-right. e Amden Fm marls (Upper Cretaceous) progressively sheared and transposed with a top to the SW sense. Rawilpass region (601465/137287)
