再论察尔汗盐湖察尔汗二级补给系统S3盐层晶间卤水分异问题

本湖Ｓ_３盐层晶间卤水（简称晶卤）分异与钾盐矿床成因密切相关．察尔汗二级补给系统范围是晶卤分异最复杂的地区，为晶卤钾矿首采区，固、液态钾盐均有可观的储量，因此，深入研究本区晶卤分异问题，有助于进一步理解“阶段性淡化”说全部内容及本区钾盐资源充分利用研究．本文详细列示了晶卤总体、三级补给系统及垂直分异区在平、剖面上的分布，据此，可知其三维空间分布状况，准确预测任意切面、方向及位置晶卤的状态，并就许多问题进行了论述，有一定理论和经济意义．

Discussion of differentiation of intercrystalline brine in salt group S_3 of Second supply system in Qarhan Salt Lakes

Differentiation of intercrystalline brine in salt group S_3 of this salt lake is closely interrelated with mechanism of potash ore beds. Qarhan second supply system is the most complicated region for differentiation of intercrystalline brine, and is also the first-drawn area of intercrystalline btine potash ore, where there are some reserves of solid liquid state potash ore. Therefore, study on differentiation of intercrystalline brine in this region is conducted further. which can help to understand the whole content of "Desalination by Stage" and study on fully utilization of potash resources. The paper shows the whole intercrystalline brine, the third supply system. and the distribution of plumb differentiation region at the vertical section. So, distribution of three-dimensional space can be known about, arbitrary section, direction condition of position intercrystalline brine can be calculated, and some aspects have been discussed. which has the theoretical and economical significance.
