老挝东泰钾镁盐矿床钾盐成生顺序成因探讨

Study on Origin of Potassium Salt Formation Sequence in Dongtai Potassium and Magnesium Salt Deposit in Laos

摘要:

通过对钾盐成生四相体系图的推演，分析Br元素在钾石盐和光卤石中含量及变化规律的差别，结合光卤石晶体形态的研究，得出老挝东泰矿区出现钾石盐在上光卤石在下的层位顺序是钾盐矿(光卤石)在形成以后发生元素迁移和重结晶作用的结果。

Abstract:

Through deduction of fourphase system digram of potassium formation, analyzing differences of Br element in the content of sylvite and carnallite variation, combining with research on carnallite crystal morphology, it is regarded that the appearance of potassium salt in the upper part, while carnallite potash (carnallite) in the lower part in Dongtai mine of Laos is caused by element migration and recrystallization role.
