| Outline of Final Research Achievements |
This study intends to clarify formation processes of conglomerates and pebbly sandstones in deepwater successions in terms of comportment deposits of coarse-grained bedforms on the basis of detailed lithofacies analyses in large outcrop belts. In particular, this study tried to revisit standard models on the formation of different types of lithofacies models of deepwater conglomerates and pebbly sandstones, which have been interpreted to be the results of deceleration and/or transformation of sediment gravity flows in downflow directions, with a new lithofacies mode. The major outcomes of the present study are that component lithofacies of some standard models can be interpreted to have formed as component deposits of downflow-migrating gravelly bedforms and different types of vertical lithofacies successions are interpreted to have formed as a result of migration and aggradation of different parts of downflow-migrating gravelly bedforms.
