抄録

Studies of sequence stratigraphy in Japan began in the early 1990s with the Quaternary successions, especially the Plio-Pleistocene of the southern Kanto area. Comprehensive geologic researches in this area provided a framework for the application of the sequence-stratigraphic principles to the onshore outcrops. The outcome of such studies represents one type of variation in the standard sequence-stratigraphic model. In particular, such studies have clarified some kinds of variations in the sequence-stratigraphic tenet. That is (1) diachroneity of systems tracts, (2) spatial and temporal relationship between high-frequency depositional sequences and parasequences, (3) relative timing of turbidite deposition in a submarine fan environment, and (4) contemporaneity of lowstand depositional systems. Furthermore, sequence-stratigraphic classification of the Quaternary successions, together with tentative correlation of sequence boundaries with the oxygen isotopic sea-level index, permits detailed chronostratigraphic correlation of such successions developed in the Osaka and Boso areas. Recently, detailed measurements of depositional rates in a Holocene sequence has been available. Such measurements identified several different patterns of depositional rates that characterize each of a wide range of shallow marine and coastal depositional systems.
