杂卤石(K_2SO_4·MgSO_4·2CaSO_4·2H_2O)是一种分布较广的钾盐矿物,几乎所有的硫酸盐型钾盐矿床中都有杂卤石,我国四川、湖北、山东都已先后发现杂卤石,研究杂卤石的形成条件,了解杂卤石与可溶性钾盐矿物的关系,成为当前钾盐找矿研究工作的重要环节。
The polyhalite (K_2SO_4 · MgSO_4 · 2CaSO_4 · 2H_2O) is a widely distributed potash mineral. Almost all of the sulfate-type potash deposits contain polyhalite. In Sichuan, Hubei and Shandong, China, Halite, the study of the formation conditions of polyhalite, understanding of the relationship between polyhalite and soluble potassium salt minerals has become an important part of the current research on potash exploration.
