| 摘 要： | 四川盆地西部宫钾卤水以深层卤水形式赋存于地下４０００余ｍ的中三叠统雷口坡组四段（Ｔ２ｌ４）盐系的碳酸盐岩储层中。富钾卤水与海水不同浓缩阶段相比，其中含Ｋ＋含量异常高，构成液态钾矿资源；Ｂｒ－、Ｉ－、Ｂ（３＋）、Ｌｉ＋等稀有组分也远超过综合利用工业品位，为优质化工原料水。富钾卤水为沉积变质和钾盐溶滤的复合成因，具有固夜态找钾的指示意义。本文为四川盆地固液态找钾提供了有价值的线索。

| Abstract: | The K-rich brine in west sichuan basin, as deep brine at a depth of more than 400m, is hosted by the evaporite-bearing carbonate reservoir in the 4 th Member of Leikoupo Formation of Middle Triassic (L2L4). It is high-quality water of insustrial chemicals. The content of k in the K-rich brine, consisting of liquid potash mineral resources, is exceedingly high compared with the sea water in the different concentration stages, and the Br-, I-, B(3 ), Li and others in it exceed the comprehensive utilization pay grade. The K-rich brine is caused by metagenesis and dissolution olution of the early-formed potassium minerals, having the signhficeance for searching for solid and liquid potash mineral resources. This paper provides valuble leads for searching Sichuan basin for boath solid and liquid potash mineral resources. |
