摘　　要：广西凤凰山银矿床位于西大明山复式背斜北东端的次级褶皱断裂破碎带中。本文基于区域构造背景,研究了凤凰山银矿床构造对矿化蚀变的控制作用,分析了控矿构造组合样式及其形成机理。认为矿体产于NWW向压剪性断裂中的局部张性地段,断裂产状变化部位以及NWW向断裂与NW向断裂交会部位是成矿有利部位。Fenghuangshan silver deposit,Guangxi,was a large scale of silver deposit.In this paper the features of ore-controlling structures and the properly model for the formation and evolution of ore-controlling structures were discussed.Results showed that ore bodies were distributed in the extensional locals of the whole compressional-shearing ore-hosting faults,and the positions with altitude variation of the NWW-trending faults and the NWW-and the NWtrending fault intersections were benefit to mineralization.
