 note = {We analyzed AMS ^<14>C dating of the core samples (core name X103, X104, X106 and X107: core length 1.2-1.4m) recovered from Lake Khubsugul in Mongolia, which records Quaternary environmental history in central Eurasian. Analytical materials were two pieces of wood fragment and total organic carbon (TOC) in the sediment of 30 horizons. The core tops have chronological range 685-12,244 BP in AMS ^<14>C age of TOC, and the bottoms have about 23,000 BP. From these results, we estimated that mean sedimentation ratio of Lake Khubsugul was 6.5cm/kyr. In this study, we also tried litho-stratigraphical analysis of the cores with AMS ^<14>C ages to reconstruct of paleoenvironmental history. The recovered cores consist of Diatomaceaous mud upper section and calcareous cleyey silt lower section in lithology, and we recognized clear boundaries between these lithofacies in every core. These lithological changes show the history of aquatic productivity in Lake Khubsugul since the last 23,000 BP, and these boundaries was estimated about 10,000-13,000 BP by the sedimentation ratio. This age is same time of beginning of global climate worming, and this fact indicates that aquatic productivity in Lake Khubsugul sensitively responded to the global climatic changes., 第16回名古屋大学タンデトロン加速器質量分析計シンポジウム(平成15年(2003年度)報告 Proceedings of the 16th Symposium on Researches Using the Tandetron AMS System at Nagoya University in 2003 日時:平成16(2004)年1月22日(木)､23日(金) 会場:名古屋大学シンポジオン Date:January 22nd and 23rd,2004 Place:Nagoya University Symposion Hall},
