长江中下游地区中更新世黄土是中国黄土高原地区以外研究最多的黄土沉积物，其物源的确定将为深入了解这一宝贵的沉积档案的环境意义以及东亚冬季风在亚洲内陆沙漠沙尘输送中的潜在作用提供重要信息。本文应用地球化学方法对中国南方长江下游黄土的物源与中国北方黄土高原黄土沉积物的物源进行了对比研究。
The provenance of middle Pleistocene loess in the middle and lower reaches of the Yangtze River the most intensively investigated loess deposits outside the Loess Plateau region in China remains contro versial Identification of the provenance will provide crucial insight into the environmental implications of this valuable sedimentary archive and into the potential role of the East Asian winter monsoon in transporting the dust from deserts in the Asian Interior In this study geochemistry was used to compare the provenance of loess in the lower reaches of the Yangtze River in southern China with that Inferred for loess deposits on the Loess Plateau in northern China Compared with samples from the Loess Plateau the
