Outline of Final Research Achievements |
It is revealed that tectono-sedimentation played an important role in the development of the benthic ecosystems of the forearc region of the Southwest Japan Arc, during the early to middle Miocene. For example, the less bioturbated forearc basin fill of the Misaki Group, Kochi Prefecture, is interpreted to have formed due to the basin-wide over-sedimentation (highly frequent and rapid sedimentation) that significantly diluted the biogenic structures in the sediment, and prevented the colonisation of animals with low burial-tolerance. Some preliminary data to help for the newly establishment of some tsunamiite facies models of the wave-dominated shallow marine setting, and so on, are also obtained. These results were published in the nine original papers, two book sections, and nine and more than twenty presentations in international and domestic scientific meetings, respectively.
