Journal of Sedimentary Research ; 63 (5): 894–898. doi: https://doi.org/10.1306/D4267C3A-2B26-11D7-8648000102C1865D
Studies of organic and inorganic diagenesis of Tertiary successions in the Kyushu-Korea region was combined with systematic correlation of the onshore geology. The degree of diagenesis can be attributed to two types of alteration: regional burial diagenesis in each locality was accelerated by additional heat supply from a zone of high paleotemperature in the Sea of Japan. This zone is related to the opening of the Sea of Japan in the Eocene.
