Stratigraphy
Formation:Takakurayama Member:Kashiwadaira
Stratigraphic resolution:group of beds
Stratigraphy comments: The Takakurayama Formation is exposed in the northeastern slope of Mt. Takakurayama, dipping 30-45 degrees W and striking in a general NNE-SSW direction, and occupying the area of about 3 square kilometers. This formation is subdivided into three members: 1) the Iriishikura Member, consisting mostly of shale with some sandstone beds, 290 m thick, 2) the Motomura Member, consisting mostly of sandstone and conglomerate with some shale beds, 167 m thick, and 3) the Kashiwadaria Member, consisting mostly of shale with some sandstone and conglomerate beds, 348 m thick, in ascending order.
