摘 要: | 四川盆地液态钾矿以地下卤水形式赋存于地下3000m的三叠系嘉陵江组及雷口被组碳酸盐储层中。卤水浓度较高,其中K含量异常高,Br,I,B,Li等已超过综合利用品位。富钾卤水为沉积变质和钾盐溶滤的复合成因。这成为四川盆地寻找液态钾矿资源的重要理论依据,并为该区含钾盐类的存在提供了有价值的线索。

FORMATION OF THE LIQUID POTASH RESOURCES ASSOCIATED WITH TRIASSIC SEQUENCES IN SICHUAN BASIN |
| |
Abstract: | Abstract The liquid potash in the Sichuan basin occurs as underground brine at a depth of 3. 000m and is associated with the carbonate units of the Triassic Jialinjiang and Leikoupou formations. The brine contains not only a unusual amount of K but more Br,I, B, Li and others than comprehensively recoverable grade. The potash-rich solution is well-accepted to attribute its formation to dissolution and metagenesis of the early-formed potassium minerals,a genetic model that both lays a theoritical base for searching for this sort of mineral resource in the Sichuan basin and provides important clues for where it possibly exsists in the basin. |
