腾格里沙漠地区盐湖卤水水化学特征

HYDROCHEMICAL CHARACTERS OF THE BRINE OF SALTLAKES IN TENGGELI DESERT REGION

盐湖卤水作为盐湖资源的重要组成部分,赋存有多种有益元素。我国钾盐资源主要赋存于西部盐湖卤水中。腾格里沙漠地区盐湖众多,普遍赋存有卤水,并以晶间卤水为主,通过对盐湖卤水的分布、化学组成及矿化特征的研究,认为本区多数盐湖含有高矿化度卤水,水化学类型以硫酸盐型为主,卤水化学特征主要受卤水演化程度以及物源条件和浓缩分异作用的控制。区内盐湖卤水K+含量较高,并有随矿化度增加而升高的趋势。

AS an important composition of salt lakes resource, there are many useful elements in brine. The sylvine resources of our country is mainy existde in the brine of salt lakes in northwest China. There are many salt lakes in Tenggeli desert region and in these lakes interorystalline brine is rich. Through the studied of distribution, chemical compositions and mineralizing characters of the brine, we find that the mineralizing degree is higher, the hydrochemical type is sulphate type and the hydrochemical characters is mainly controlled by evolutionary process as well as physical geochemistry conditions and concentrating differentiation of the brine, the content of K+ is higher in the brine and it is showing a tendency to go up along with the growth of the mineralizing degree.
