内容記述タイプ Abstract
内容記述 The boring core KM-11, located at the center of Lake Kamo, Sado Island, provided a good opportunity to examine the Late Pleistocene and Holocene diatom biofacies. Fossil diatom assemblages in the core as well as sedimentary properties were useful for examining historical changes of Holocene sedimentary environment and relative sea level. Based on ecological groups, diatoms of this site are classified into 14 ecological groups. They are marine planktonic, marine epiphytic, brackish planktonic, marine/brackish epipsammic, marine/brackish epipelic, marine/brackish aerophilous, marine/ brackish epiphytic, brackish/fresh tychoplanktonic, brackish/fresh epiphytic, brackish/fresh planktonic, brackish/fresh aerophilous, fresh water epiphytic, fresh water planktonic and fresh water epipelic diatom groups. The stratigraphical change of these groups is divided into seven diatom divisions. Each diatom division is closely related to the evolution of sedimentation caused by Holocene sea level and geomorphological changes. In the Late Pleistocene, fluvial sediments were deposited in the site, then overlain by estuary sediments at the beginning of the Holocene transgression. Following the maximum Holocene transgression in 5,000 yr.BP, two small regressions occurred alternatively with two small transgressions respectively. After 1,800 yr.BP. fresh/brackish lacustrine sediments were deposited and marine/brackish lagoonal sediments have been deposited again since 1902 due to the construction of an artificial water way.
