| Research Abstract |
(1)We studied the stratigraphic transition of major and minor elements in terms of some statistical methods from the Sorachi to the Yezo Group as well as of radiolarian abundance and specific compositions. in Teshionakagawa area, Hokkaido. We clarified that the chemical transition is much different from the clear visual change in the succession between the upper Sorachi and the lower Yezo Groups.
(2)We made a joint work on the same sections of the upper Cretaceous in Nakatonbetsu area, Hokkaido from the viewpoints of biostratigraphy by using ammonoids, inoceramids, planktonic foraminifers, sequence stratigraphy, and stable carbon isotope stratigraphy. We detected a significant spike of carbon isotope fluctuation at the same stratigraphic horizon of the extinction of inoceramid bivalves. This result enable us to make a high resolution international correlation.
(3)We made a joint research on the Jixi Group in NE China of the provenance of the Yezo forearcc basin from the viewpoints of biostratigraphy of marine bivalves, pollen, stable carbon isotope stratigraphy and sequence stratigraphy. We obtained a high resolution correlation of the group with the Japanese Pacific, and European sections.
