| Research Abstract |
The Niigata plain records the eustatic sea-level change and intermittent sedimentation by earthquake. The two boreholes are drilled in the lagoon, and depositional facies analysis, microfossil analysis and total sulfur quantity analysis, etc. was examined. As this result, there was 3 times of the marine transgression after Jomon transgression, and it became clear to change to the inland into the brackish water environment. This change is also recorded for the change of depositional facies of the barrier system. It became clear that the rapid subsiding was generating the regression of the system from the viewpoint of the transition of the barrier system. It is considered that it is based on the active concealed fault, which subdues such rapid sedimentation.
