从四川盆地盐类变质资料看找钾方向

THE PROSPECTS FOR THE SEARCHING FOR POTASH SALT IN TERMS OF METAMORPHISM OF SALT FORMATION IN SICHUAN BASIN

四川盆地三叠系盐类在地史经历中，经受强烈的热融和水溶变质作用，使盐类沉积原始面貌发生深刻变化。（钾组分转入液相，形成液态钾盐—富钾卤水）现剖面所见硬石膏、杂卤石、硫镁矾、无水钾镁矾等多系热融和水溶变质产物。面对这一现实，理顺和拓宽四川找钾思路，勘查开发液态钾盐，是四川找钾的新方向。

Triassic salt formation in Sichuan basin has undergone intense thermomelting and aqueous dissolution which resulted in transference of potassium into liquid phase with formation of liquid potash salt-K-rich brine. Existing anhydrite, polyhalite, niningerite and langbeinite result from thermomelting and aqueous dissolution. From this it is concluded that we should search for liquid potash salt in Sichuan basin.
