| Outline of Final Research Achievements |
Age population diagrams obtained from detrital zircon-monazite U-Pb analysis for the latest Triassic to early Jurassic units of both Inner and outer zones of Southwest Japan are clearly differ from each other. From this evidence, the accumulated displacement along MTL can be estimated at least 800 km or more.
The boundary between Abukuma Belt and Kitakami Belt can be traced from Hatagawa Tectonic Line passing through the Onikobe-Yuzawa mylonite zone, Kyowa-Hitachinai mylonite zone in the Taiheizan granitic complex and east of Mt. Shirakami to east of Okushiri island by zircon chronology for granitic rocks.
Mid to late Cretaceous Chugoku province was thoroughly covered by more than 1000 m thick ignimbrite whose onset was marked by eruption of Kisa andesite at 111 Ma.
