抄録

Holocene cores with many highly dense 14C ages present new methods for stratigraphy. For example, the following new information can be obtained from the Holocene in the southern part of the Miura and Boso Peninsulas, such as, 1) development over time of a sequence during a transgressive-regressive cycle; 2) time-series of the progradation of beach-shoreface systems; 3) variation of paleo-depths; 4) accumulation (depositional) rates and rates of sea level rise; 5) explanation of disagreement between age and stratigraphic horizon; 6) recognition of tsunami deposits and determination of ages; and 7) crustal movements of earthquake uplifting area. The unique information is shown with short time errors within 100 years, and is also given as a time-series and variation rates. This dynamic information and the interpretation of Holocene strata will introduce a new paradigm in sequence stratigraphy and sedimentology.
