Coupled micro-faulting and pressure solution creep overprinted on quartz schist deformed by intracrystalline plasticity during exhumation of the Sambagawa metamorphic rocks, southwest Japan

► Quartz microstructures in quartz schist were once formed by intracrystalline plasticity. ► These were overprinted by deformation at the frictional-viscous transition conditions. ► Intracrystalline microstructures became obliterated with increasing shear. ► The obliteration of microstructures is probably caused by dominant pressure solution creep. ► This is evidenced by the increasing portion of quartz-newly precipitated mica interface.
