Outline of Final Research Achievements

We geologically investigated in the Paleozoic and Mesozoic fields, Southeast and East Asia, mainly in the Devonian to Carboniferous and Permian to Triassic in Vietnam. We revealed geologic ages in detail on the basis of conodont biostratigraphic data, and reported mass extinction events and global anoxic to dysoxic events around Devonian-Carboniferous boundary (DCB), the Lower Triassic Induan-Olenekian boundary (IOB) and Smithian-Spathian boundary (SSB). The depositional environments and fossil assemblages in several sections intercalating with DCB, SSB and IOB were reconstructed by facies analysis and paleosynecological study methods. Finally we discussed about natural histories of marine organisms after extinction events thorough recovery intervals to adaptive radiations each depositional environments.
