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., タンデトロン加速器質量分析計業績報告 Summaries of Researches Using AMS 1997 (平成9)年度}, pages = {212--227}, title = {肝属平野の形成史 : テフラとAMS^<14>C年代による}, volume = {9}, year = {1998} }
