This paper documents the occurrence of large amounts of talc within a continental normal fault. The talc-in reaction is deformation-enhanced and occurs by the interaction between dolostones and silica-rich hydrothermal fluids. In the high-strain, foliated fault core, talc forms an interconnected network of oriented (001) lamellae, 200–300 nm …
