| Research Abstract |
Tephra analyses have been performed for muddy core samples(Oh' e and Nabeta cores) recovered from coastal area of the Nohbi Plain, Aichi Prefecture, central Japan. Several widespread tephras are identified. Based on identified tephras, the subsurface geology has been studied. As a result, the following new aspect has been revealed.
Namely, it seems likely that the westward Nohbi Tilting Movements delayed the subsidence of eastern part in comparison with the western part, and the subsidence was so small scale in the eastern part. But the marine clay members had deposited earlier and thicker in the eastern part. These facts suggest that the tilting movement has occurred not continuously but intermittently.
