 note = {application/pdf, 論文(Article), In the Chichibu Terrain of the Yatsushiro Mountains in Kumamoto Prefecture, the Lower Cretaceous System of  the study area is divided into the “Monobegawa ” and Pre-Sotoizumi (emend.) Groups.  The “Monobegawa” Group is composed of the Kohara, Mitsumineyama and Toyo (New name) Formations in ascending order. The Pre-Sotoizumi Group can be divided into three formations, which are Hachiryuzan, Kesado, and Imaizumi Formations in ascending order. In this paper, the stratigraphy is described in some detail, with remarks on correlation, and the features of the bivalve faunas are made clear.
In the Chichibu Terrain, many characteristic bivalve faunas have been recognized from various localities of different depositional environments and geologic ages. They are roughly grouped into the Tethyan Faunas and the Northern-Tethyan faunas. The Northern-Tethyan faunas of the study area occur from the “Monobegawa” Group, i.e. Kohara and Mitsumineyama Formations. On the other hand, the Tethyan Faunas of the study area have been reported from the Pre-Sotoizumi Group, i.e. Hachiryuzan and Kesado Formations.
Data from biostratigraphic study, as well as field evidence, indicate that the Pre-Sotoizumi Group is thrust over the “Monobegawa” Group bounded on very low angle faults.},
