Outline of Final Research Achievements

The objective of this study is establishment of stratigraphic and chronological model of the Pliocene to Pleistocene Series, which are distributed on land and under the sea around Japanese archipelago. We described and analyzed tephra beds in the cores, which are drilled around Japanese archipelago by the International Ocean Discovery Program (IODP). Some of tephras are correlated with between each core based on their specific properties, and also these tephras are correlated with known widespread tephras on land. We tried to establishment of the stratigraphic and chronological model of the Japanese Pliocene-Pleistocene Series by these correlated tephras.
