超基性岩体(橄榄岩)已完全蛇纹石化了。主要蛇纹石结构有网状结构,砂钟结构等。渐进蛇纹石化作用的发育对纤蛇纹石石棉的形成是有利的.本区蛇纹石化的特征之一,是叶蛇纹石的广泛发育,而且是在石棉矿床的主要成矿期(或稍早)的中温条件下形成的。蛇纹石化过程中主要元素均表现了活动性。部分 Si 是从相对富 Si 岩石迁入蛇纹岩的,Mg 和 Al 从围岩蛇纹岩向蛇纹石脉迁移。Ca 和 Fe 从原有矿物迁出,形成碳酸盐矿物和磁铁矿.
The ultrabasic rock (olivine) is completely serpentineized. The main serpentine structure has a network structure, sand clock structure. The development of progressive serpentinization is beneficial to the formation of chrysotile asbestos. One of the characteristics of serpentinization in this area is the widespread development of serpentine, and is the main mineralization period of asbestos deposits (or Earlier) formed under medium temperature conditions. The main elements of serpentinization show activity. Some Si migrates from the relatively rich Si rock into serpentine, and Mg and Al migrate from the surrounding rock to serpentine veins. Ca and Fe migrated from their original minerals to form carbonate minerals and magnetite.
