Biostratigraphy and Correlation of the Permian of Japan

Abstract

Permian biostratigraphy is described for seven selected districts in Japan. A new biostratigraphic scheme is presented for the Permian in the Kitakami mountains, based on a number of assemblage zones. New names, Maehama and Nabekoshi Stages are proposed in the Toyoma Series of the Kitakami mountains. An attempt is made to correlate the Japanese Permian in the studied districts.
