| Outline of Final Research Achievements |
This study aimed at establishing a standard calcareous nannofossil biohorizons in the Pacific side of the Japanese islands that can be useful to determine geologic ages around the Northwestern Pacific region. In this study, we examined Miocene to Pleistocene strata distributed in the Boso Peninsura and core samples obtained from the Nankai Trough Seismogenic Zone Experiment (NanTroSEISE Project). As a result, useful biohorizons during the late Miocene to Pleistocene were clarified in relation to magnetostratigraphy and oxygen isotope stratigraphy. Especially, we firstly reported that calcareous nannofossil biohorizons from the late Pliocene to Pleistocene were directly correlated with oxygen isotope stages in the southern Boso Peninsura and they can be applicable to the northwestern Pacific region.
