依据 TL和 1 4 C测年数据及各项环境指标分析 ,对九江—红光澎泽一带沙山剖面进行了研究和对比 ,讨论了 147ka B.P.至晚冰期的年代地层序列和古气候环境 ,同时对沙山成因、古湖沼形成机制进行了深入探讨。该区沙山地貌并非新构造运动所致 ,属差异侵蚀作用的结果 ,泥炭层由风积地区沙丘间湖沼沉积形成
Based on the TL and 1 4 C dating data and the analysis of various environmental indicators, the Shashan section of Jiujiang-Hongguang PENGze area was studied and compared, and the sequence and palaeoclimate environment from 147 ka BP to late glacial stage were discussed. Meanwhile, On the causes of sand, ancient lake formation mechanism in-depth discussion. The sandy landform in this area is not caused by the neotectonic movement. As a result of the differential erosion, the peat layer is formed by deposition of lacustrine sand dunes in the aeolian area
