摘　　要：湖南西部钨锑金矿床主要集中分布于雪峰弧形构造带内， 赋存于元古宇浅变质岩系中， 严格受断裂构造控制。矿种组合为一组具有成因联系的 Ｗ  Ｓｂ Ａｕ、 Ｓｂ Ａｕ、 Ｗ  Ａｕ 和 Ａｕ、 Ｓｂ 等矿床成矿系列。各矿床具有相似的区域构造地球化学环境、形成规律及成因机制。在元古宇浅变质岩系中控矿构造系统发育的区（带） 是金矿有利的远景区 （带）。W Sb Au deposits in Hunan are mainly centralized in Xuefeng arc shaped tectonic zone and occur in the Proterozoic epimetamorphic rock series. The deposits are directly controlled by fault structure. Mineral assemblages are metallogenic series of W Sb Au , Sb Au, W Au, Au and Sb deposits, which have genetic relation. They have similar regional tectonic geochemical environment, forming regularity and genetic mechanism. Therefore, in the Proterozoic epimetamorphic rock series, the development belt of ore control structures is the favorable prospecting region (belt) of gold deposit.
