Abstract
Constraining of the timing of fault zone formation is of fundamental geotectonic importance to understand structural evolution and brittle fault processes. Here, we present authigenic illite K-Ar age data from brittle fault zones comprising two gouges within the Toki granite, central Japan. The gouge samples were collected at depths of 252.9 and 403.7. m from a shaft at the Mizunami Underground Research Laboratory, and were separated into five grain-size fractions (
