[HQR15-P02] Stratigraphy of the Middle to Late Pleistocene in the southwest Hokkaido, Japan
Keywords:southwestern Hokkaido, Setana Formation, Stratigraphy
Sedimentary age of Setana Formation has been estimated to be 1.2 Ma to 0.6 Ma by biostratigraphic investigation. But there aren’t a lot of previous research about Stratigraphic Relation between Ohyachi Formation and Setana Formation and that’s geomorphic development.
Recently, Kondo et al. (2016) got Setana Formation’s and Ohyachi Formation’s conclusive age by OSL. The purpose of this study is to clarify the Stratigraphic Relation and the paleo-environment by Sedimentary age.
