Rare earth element signatures of Taklimakan Desert aeolian sediments based on rare earth element signatures

We collected sediment samples from six dune types and one dry lake deposit from the TKL. We used the sediment rare earth element signatures to identify their sources and analyze the spatial variation of these element and their ratios.本研究从TKL的六种沙丘类型及一处干湖沉积体中采集了沉积物样品，利用沉积物的稀土元素（Rare Earth Element）指纹特征识别其物源，并分析了这些元素及其比值的空间变化。
