| Research Abstract |
In this study, we systematically revealed petrological characteristic such as major elements composition of volcanic glass shard, pyroxene and hornblende which included in Plio-Pleistocene large-scale pyroclastic flow deposits in the Kyushu Island and Miocene to Pleistocene tephra beds in sediment cores drilled at the Nankai Trough. Based on stratigraphical and chronological study, it is possible to evaluate frequency of caldera-forming eruptions in the Kyushu Island and silicic marine explosive eruptions at Izu-Bonin Arc.
