AMS^<14>C年代
This paper discusses the formation of the Kimotsuki Lowland, southern Kyushu, during the middle and late Holocene, based on tephrochronology and AMS ^<14>C dating. The results are as follows. The most landward barrier was formed 5,500~5,700 years ago, turning a bay invaded by the Holocene transgression into a lagoon. The altitude of relative sea level at that time is 3-5 m above the present sea level. Five tephralayers are interbeded in the peat layers, four of which are identified with Sakurajima-Takatoge 2 (4.5 ka), Kirishima-Miike (4.2 ka), Kaimondake-9c (2ka) and Kaimondake-12a (A.D.874) from older to younger. Some AMS ^<14>C dates obtained from basal peat, together with these tephras, indicate that the accumulation of peat began 5,600 to 5,000 years ago and lasted at least for 4,000 years.
