Research Abstract |
Clay mineral characteristics in and around the slip surfaces of frontal thrusts in the Miura-Boso accretionary prism was analyzed for better understanding of their slip behaviors. XRD and TEM analyses revealed a local progress of illitization reaction only within the fault gouges. This reaction might be driven by transient thermogenesis along the slip surface, and indicates probable co-seismic slip propagation up to the prism toe at the subduction margin.
