| Outline of Final Research Achievements |
It seems that seismogenic faults will be found in on-land accretionary complexes such as the Jurassic accretionary complexes distributed in the Japanese Island. In contrast to the Cretaceous accretionary complex of the Shimanto Belt, the Jurassic accretionary complexes such as the Ashio Belt are characterized by the accretion of the seamount-type limestone and basaltic rocks. A fault rocks separating the limestone-basaltic rock unit and chert-clascic rock unit was found out and was described. Paleogeothermal by the illite crystallinity measurement, U-Pb dating of the zircon, and Fission track dating had been done in the southern part of the Ashio Belt to clarify the geothermal structure, the kinematics of the boundary fault, and the timing of the fault activity.
