 note = {This paper discusses on the paleoenvironmental changes of the small alluvial lowlands by the Lake Furen in eastern part of Hokkaido, northern main island of Japan. Samples obtained by peat-corer were used for sedimentary facies observation, AMS radiocarbon dating, and diatom analysis. The upper Holocene sediments in Furen river lowland are composed of silty and peaty sediments over sandy sediments. Two or three volcanic ash layers also develop in the upper Holocene sediments. There are two sedimentary gaps which show the beginning of peat bogs expansion in the upper Holocene sediments, ca.4,500yrBP and ca.2,800 to ca.2,600yrBP. It is considered that the sedimentation of peat has been influenced by the regression of the middle and Late Holocene relative sea-level., タンデトロン加速器質量分析計業境報告 Summaries of Researches Using AMS},
