| Research Abstract |
The Alluvium of the coastal plain in Japan has been considered as formed by sea-level change. However, it is predicted that formation of Alluvium has received the sediment supply by tectonic movement or volcanic activity, etc. In the Takada plain, 4 times of volcanic large-scale sediment supply events have been recognaized by this research. These sediment supply events have brought about rapid sedimentation and changes of depositional environment of the alluvial plain.
