| Research Abstract |
I established detailed biostratigraphy of planktonic foraminifera and dinoflagerata systs in the Aptian-Maastrichtian sequence of the Yezo and Nemuro Groups exposed in Hokkaido, Japan. Based on above biostratigraphic correlations, I integrated carbon and strontium isotope stratigraphy and 12 U-Pb and 40Ar/39Ar radiometric dating of tuff beds This integrated stratigraphy has enabled to high resolution international stratigraphic correlations.
