摘　　要：依据潜江凹陷潜江组地球化学分析资料,以与盐岩紧密共生的粘土矿物微量元素分析为基本方法,通过详细研究潜江组各层序粘土矿物微量元素丰度并与物源区各岩类微量元素进行比较,认为潜江凹陷潜江组盐湖沉积的物源主要来自于酸性岩物源区和较老的含盐地层。Based on the data of geochemical analysis of Qianjiang Formation in Qianjiang Depression, microelement analysis of clay minerals closely associated with saline rocks is used as a basic method. By studying in detail microelement abundance of clay minerals in each sequence of Qianjiang Formation and contrasting with the microelements of each rock in the source area, it is considered that the source of salt lake in Qianjiang Formation is mainly from acidic rock source areas and older salt-bearing formation.
