摘　　要：首次对江陵凹陷深层天然卤水成因进行研究,初步明确江陵凹陷的天然卤水为沉积成因,具有分布广、矿化度高等特点。其中砂岩中天然卤水高矿化度分布具有明显的规律性,即越靠近洼陷或盐岩地层,天然卤水的矿化度越高;并通过化学成分分析,表明了江陵凹陷存在大量富含微量元素卤水的流体矿床,且矿化度越高所含的微量元素含量越高,部分元素为国家紧缺矿产资源,如钾、铷、铯等。The origin of deep natural brine in Jianglin depression was studied for the first time. The authors detected that the natural brine is of the sedimentary origin and characterized by wide distribution and high salinity. In the sandstone, the distribution of high-salinity natural brine shows obvious regularity： the closer the natural brine to the sag or salt strata, the higher the salinity of the natural brine. The chemical composition analysis shows that the Jiangling depression is rich in brine fluid deposits which contain lots of trace elements and have higher salini- ty. The higher the mineralization intensity, the higher the trace elements content, and some elements are na- tional badly-needed mineral resources, such as K, Rb and Cs.
