沃溪金、锑、钨矿床成矿地质特征及找矿前景分析

沃溪金、锑、钨矿床，在大地构造位置上，处于江南古陆南缘的雪峰弧型构造隆起带的中段，是江南古陆金矿成矿带上一个金、锑、钨共生的大型矿床。根据实地考察，通过对该矿床成矿的构造背景及区域成矿地质、地球物理、地球化学特征等方面的研究，认为燕山运动所导致的岩体侵位为区内成矿提供了热源，区内断裂构造的发育为成矿提供了良好的构造条件，元古宙浅变质岩系作为金矿的赋存层位，在成矿作用过程中提供了一定的物源，在该矿床的深边部及其外围有着巨大的找矿潜力。

Discussion on the mineralization geological features and metallogenetic model of Woxi Au-Sb-W deposit in west Hunan

Woxi Au-Sb-W deposit in west Hunan locates on the south edge of Jiangnan Ancient Land.It lies in the middle section of Xuefeng arc type structure upheaval belt and is a large Au-Sb-W symbiotic deposit in the ancient land.Through site investigation and project research on the characteristics of metallogenetic structure background,region metallogenetic geology,geophysics,geochemistry and etc,authors believe that the magma intrusion which caused by Yanshan Movement,supplied the heat source during the course of metallization in this area.The faults developed in the region offered good structure condition for mineralization,the series of metamorphic rock of proterozoic group was the strata where the deposit occurred,which provided material source in the process of metallization.The mine has great potential of ore prospecting in the surrounding area of the present deposit.
