説明
This paper discusses the relative Holocene sea level change in a small lowland of Takagami, located on the central part of the Choshi Peninsula, easternmost of Kanto district. Samples obtained by drilling machine and peat-corer were used for radiocarbon dating, sedimentary facies observation and analysis of molluscan, diatom and pollen assemblages. Our data, combined with our first report (OTA et al., 1985), reveal that the Postglacial transgression has started at c. 10, 000y.B.P. at the latest. A rapid sea level rise has continued till c. 7, 000y.B.P., followed by a decrease of water depth. The upper limit of marine deposits is about 4.0m above mean sea level. The culmination of relative sea level rise has occurred at about 5, 500y.B.P., judged by clustering of radiocarbon ages of the lowest terrestrial peat bed in c. 5, 000-5, 500y.B.P. Since then, sea level probably has lowered to the present position without any intermittent uplift.
