新疆若羌县米兰—罗南一带含钾卤水组分及特征

Composition and characteristics of potassium bearing brine in Milan-Ronan area, Ruoqiang County, Xinjiang

若羌县碱水泉米兰-罗南一带液体钾盐矿作为罗布泊液体钾盐矿的重要组成部分,储卤层主要由碎屑层和石盐层组成,部分为石膏层。富钾卤水主要赋存于碎屑层和盐类矿物的晶间,属孔隙卤水和晶间卤水混合型,根据其沉积韵律相对应地划分为潜卤水层矿体(W1)和承压卤水层组矿体(W2)各一个,矿体之间被相对稳定的粘土层所分隔,潜卤水与承压卤水矿体矿化度均在100~300g/l,为高矿化卤水。

The liquid potash ore in the Milan Ronan Ronan area of the alkali water spring of Ruoqiang county is an important part of the liquid potassium salt mine of Lop Nor. The halogen layer is mainly composed of clastic layer and stone salt layer, and part of the gypsum layer. The potassium rich brine mainly occurs in the intergranular between the clastic layer and the salt mineral, and is a mixed type of pore brine and intercrystalline brine. According to its sedimentary rhythm, the halogen water layer ore body（W1） and the bearing brine layer group ore body（W2） are divided. The ore bodies are separated by the relatively stable clay layer, and the submersible brine and the bearing halogen ore are used. The mineralized degree of ore body is 100 - 300 g/l, which is highly mineralized brine.
