摘　　要：广西黑水沟锌多金属矿床位于扬子克拉通边缘,江南古陆西南缘、右江盆地北东侧,矿床内已发现7条主矿体和44条支脉矿体,均产于泥盆系中.大厂断裂为本区的导矿构造,黑水沟断裂对成矿有重要的控制作用,大厂背斜的层间错动带为后期成矿提供了良好的赋存空间,矿体的形成是由于含矿流体沿层交代或含矿流体充填不同部位层间滑脱(剥离)形成的"虚脱空间"形成的.The Heishuigou Zn-polymetallic deposit in Guangxi is tectonically located in the southwest of Jiangnan oldland and the northeast of Youjiang basin, on the margin of the Yangtze craton. Seven main orebodies with 44 ore veins, which occur in the Devonian formations, are found in the orefield. The Dachang fault serves as the ore-guiding structure. The Heishuigou fault plays an important role in the control of metallogeny. The faulted bedding plane of Dachang anticline provides a proper space for later mineralization. The ore-bearing fluids replace the strata or fill in the space by decollement to form orebodies.
