| 摘 要： | 西山庄金矿位于翼城县境内,为一小型金矿床,处于晋南塔儿山-二峰山铁、多金属成矿区内。区内发育多期次剪切带型构造,诱发了中酸性岩浆的侵入,同时也促使了深部含金丰度较高的古老变质岩系中的金发生反复活化迁移富集而成矿。整个岩浆岩成岩过程处于强烈的构造活动中,早期岩体受到破碎形成破碎带,后期含矿流体向破碎带迁移、沉淀并形成广泛的热液蚀变,形成蚀变破碎带型金矿化(床)。

| Abstract: | Xishanzhuang gold deposit is a small gold deposits located in Yicheng County. ,in Taershan-Erfengshan iron and polymetallie mineralization zone in south of Shanxi. The development of multi-phase shear zone type structure, induced the acidic magma in the invasion, at the same time also prompted repeated activation, migration and enrichment of ore in the deep ancient altered rock with high gold abundance. The whole formation process of magmatie rocks undergone intense teetonic activities, the early rock formed fracture zone, later ore-bearing fluid migrated to fracture zone and precipitated to extensive hydrothermal alteration, eventually forming the altered fracture zone type gold mineralization. |
