Outline of Final Research Achievements

Thermal and mechanical activations on hydrous clay minerals in fault zones are examined. High-temperature XRD experiments demonstrated that kaolinite and chlorite, typical clay components in crustal faults, dehydroxylate in a different manner, which can be utilized as a new temperature proxy for seismogenic faults in subduction zones. In addition, we showed that mechanical action can facilitate mineral dehydroxylation reaction due to selective degradation of clay interlayers connected by hydrogen bondings. We also investigated smectite/illite mixed layers around a slip zone of the mega-branching fault of the Nankai Trough, and showed that mechanochemical processes possibly associated with seismogenic faulting can activate its transfrormation reaction by reducing the activation energy of the reaction.
