| Research Abstract |
This study intended to establish a reconstruction of basin genesis and sedimentation of the backarc rift basins with multiple structural trends. The study area includes three localities in the northern part of the Niigata basin where Miocene to Pliocene sediments and faults hosted by them are well exposed. During the basin genesis, several different structural trends were effective to formation of rift-border faults and other minor deformation within the basement. However, the most effective trend in each area varies between the localities. In addition, variation in thickness and depositional facies right above the basement was affected by that of the fault activity. The results will be incorporated in studies in fossil fuel exploration and disaster science.
