Pelagic-sourced is most abundant clay mineral that incorporated into zone was drilled Fast Drilling Project (JFAST) Expedition 343 Trench, located ∼820 m below seafloor. study investigates preserve a record coseismic frictional associated with May laboratory examination hydration dehydration JFAST drill core samples (maximum 5 min) (5 h) sequences. Using real-time stage connected an X-ray diffractometer, we observe (1) both causes reduction water interlayers smectite, (2) recovers faster original state after quick than long heating, (3) nonrecoverable collapse all occurs at >200 °C rates. Because hydrated, clays are widely present fault rocks, conclude within cannot have reached significantly elevated temperatures.
