Outline of Final Research Achievements |
Because oceanic plates are subducted into the Earth interior within 200 m.y. since their birth, oceanic rocks incorporated in accretionary and ophiolitic terranes exposed on land play important roles on reconstruction of ancient oceanic plate configuration. This study examined petrology, stratigraphy, and geochronology of Mesozoic accretionary complexes and ophiolites in Hokkaido. The obtained data suggested existence of intraoceanic arc-trench systems independent from Eurasian active continental margin in the Mesozoic NE Pacific. It is probable that Japanese Islands developed under interactions between at least four tectonic plates in Jurassic to Cretaceous periods.
