Abstract: Recently the writer has established by means of the pollen-spore assemblages the zoning of the Paleogene and Lower Miocene deposits in northern Kyushu. T. NAGAO (1928) correlated the Onga formation with the Yoshinotani formation and proposed the "Onga regression" which took place widely in northern Kyushu. H. MATSUSHITA (1949) supported this opinion of Nagao. The writer has pointed out their mistaken correlation and verified biostratigraphically the new correlation of the non-marine Onga formation with the marine Kishima formation. He has found many pollen and spores from the shale of the plant bed at Hiagari in the Kokura coal-field and proved that this pollen assemblage belongs to the Sasebo pollen group. Accordingly, as at the least the plant bed at Hiagari can be correlated with a part of the Ashiya group, a concept of the contemporaneous heteropic facies must be adopted. He has proposed the Onga subsidence which had brought mainly the deposition of non-marine sediments and partially the intercalation of marine sediments containing the molluscan fossils in the middle or upper horizons. At the age of the Onga subsidence, the transgression in northwestern Kyushu had brought the deposition of the marine Kishima and Mase formation. The writer has studied only a few pollen and microplankton from the medium sandstone of the Nokonoshima formation in the Fukuoka coal-field.
