摘要
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.
