察尔汗盐湖察尔汗二级补给系统S3盐层晶间卤水中KCl的分异特征、富集规律及其成因

据ＫＣｌ含量的概率分布特征，晶间卤水分为７个总体。晶间卤水ＫＣｌ，在三级系统内水平分异有２种、剖面分异有５种，二级系统内水平分异呈环带状、剖面分异形式为三级系统内分异形式的组合，垂直分异有１３种；富集的总体为Ⅳ（ｋｃｌ）、Ⅲ（ｋｃｌ）用Ｖ（ｋｃｌ）、三级系统为（８）和（１０）号、部位为固相钾高含处；分异及富集的成因主要为晶间卤水的阶段性淡化。

Differentiation Characteristics, Concentration Rules And The formation Mechanism f KCl In Intercrystalline Brine in Salt Group S_3 of Qarhan Second Supply System of Qarhan Salt Lake

The interystalline brine is divided into 7 populations according to the probability distribution characteristics of the KCl content. Horizontal differentiation of intercrystalline brineKCl has 2 types and the sectional differentiation has 5 types in third supply systems. In thesecond supply system, horizontal differentiation is in a circular -- belt form and sectionaldifferentiation is the combination.of the differentiation forms in the third supply system. Thevertical differentiation has 13 types. Concentrated populations are Ⅳkcl, Ⅲkcl so and Vkcl,andconcentrated third systems are No. (8) and (10). Concentrated positions are places rich insolid-K. Mechanism of the differentiation and concentration is mainly the intercrystallinebrine's desalination by stage:
