摘　　要：察尔汗盐湖是我国已探明的最大的钾镁盐矿床,其卤水矿物质的来源及形成受周边山区地层及岩浆岩类物质组分、青藏高原的隆升作用而导致的成山成盆运动、古气候环境等因素控制,具有开采价值和开采潜力的主要钾镁盐矿层分布于第四纪地层中。Qarhan Salt Lake is the largest K-Mg salt deposit with proven reserves in China. The formation of K-Mg salt deposit is controlled by several factors： strata and magmatite material components of surrounding mountain area, the mountain-building and basin-formation movement caused by Qinghai- Tibet Plateau movement, paleoclimate and paleoenvironment, and other factors. Promising K-Mg salt deposit is mainly distributed in Quaternary stratum.
