The results revealed that two rocks are clearly distinguished by the degree of organic maturation level. The Ushitakigawa Clastic Rock had reached the stage of catagenesis / post mature parity with the Izumi Group, and its high maturity was probably caused by the influence of deep burial diagenesis. The Kannabi Formation had reached the stage of diagenesis / immature but is assumed to be weekly baked at a few km burial depth. The thermal maturation levels of the Kannabi Formation are compatible with stratigraphy and geologic history shown by previous studies. The Sobagawa Conglomerate must have been thermally metamorphosed at high temperature as maturation level can not determined by Rock-Eval pyrolysis and vitrinite reflectance.},
