摘　　要：分析表明,湘西沃溪金锑钨矿床是后生热液矿床,热液来自于矿区深部,仙鹅抱蛋穹窿、拖毛岭穹窿及沃溪大断层共同作用形成容矿裂隙,来自深部的含矿热液充填形成矿体,沃溪大断层是非顺层断层,是成矿期断层。受沃溪大断层的阻隔,其上盘不存在同源热液矿体。It is shown that the Woxi Au-Sb-W deposit is of epigenetic hydrothermal origin, and the ore-forming fluid was derived from the deep-seated in the mining district. The Xian＇ ebaodan dome, Tuomaoling dome and the Woxi fault constitute the space for ore precipitation in the Woxi deposit. The Woxi fault is a syn-mineralization fault rather than a bedding fault. Due to the presence of the hampering from the Woxi fault, it is impossible to find ore bodies in the hanging wall of this fault.
