| Outline of Final Research Achievements |
Thermal history of fault zones were analyzed by thermochronology, in order to reconstruct the history of fault motions as well as to quantitatively assess relevant heat generation and transfer. The estimation of the time of fault motion and modeling of heat generation and transfer were conducted by applying the fission-track and other methods to seismogenic zone faults of plate subduction zone. As a result, the time of heating episode was estimated as 48±6Ma(2SE) by thermal history inversion of zircon FT data. The age is best interpreted by the time of activity of“out-of-sequence thrust” during the formation and evolution of the Shimanto accretionary complex.
