摘　　要：文章在详细梳理维寨锑矿床地质特征的基础上,分析皱褶、陡倾斜断裂、顺层滑脱带、地层界面及岩性界面的控矿作用。矿床受独山箱状背斜次一级褶皱庙寨—巴年背斜控制,矿体受牛硐断层、层间滑脱带及有利的地层、岩性界面控制,矿体就位于断裂产状变化处、分支复合处,以及与有利岩性组合的交汇处。提出高寨田组(S_(1)g)下部碳酸盐岩与碎屑岩组成的“硅钙面”及其与下伏地层烂木滩组(O_(2)l)不整合面与牛硐断裂叠加处,是寻找深部隐伏矿体的有利区域。Based on the detailed review of geological characteristics of the Weizhai antimony deposit,this article analyzes the ore-controlling effect of the fold,steeply dipping fault,interlayer slipping zone,stratigraphic interface and lithological interface.The deposit is controlled by the Miaozhai-Bannian secondary anticline of Dushan box-shape anticline.The orebody is controlled by the Niudong fault,interlayer slipping zone,and favorable stratigraphic and lithological interfaces.The orebody is located at the place of fault occurrence variation,branch and recombination,and at the intersection with favorable lithological combination.The"silicon calcium surface"composed of carbonate rocks and clastic rocks in the lower part of the Gaozhaitian Formation(S_(1)g)and its unconformity with the underlying formation of Lemutan Formation(O_(2)l),as well as the Niudong fault.It is proposed as the favorable area to exploration for the deep-seated hidden orebodies.
