摘　　要："镇龙山穹窿"位于广西宾阳、横县、贵港三县市交界位置,穹窿内银、铜、铅、锌、锑、砷、金矿化带沿着北部和南部两条深大断裂展布,穹窿外缘沉降地带则少见矿(化)点。地层建造、构造活动、岩浆活动共同控制着本区的成矿,地层为成矿提供了部分物质来源,含炭建造起到活化地层中成矿元素的作用;构造活动使地层发生动力变质作用,构造控制着岩浆的侵入和矿(化)点的分布;岩浆活动为成矿带来大量的成矿物质,并控制本区的矿化类型。Zhenlongshan fornix is located at the junction position of the Binyang, Hengxian, Guigang coun- ties, in Guangxi province. Mineralization belts of Ag, Cu,Pb,Zn, Sb,As,Au is mass distributed along the two deep faults of northern and southern part but less in the outer settlement zone of the fornix. The miner- alization is controlled by the stratum construction, tectonic activity and magma activity. Strata provided some metallogenic material sources for mineralization and carbon-containing construction played a role in ac- tivating the metallogenic elements of strata. Tectonic activities prompted the stratiagraphic occurrence of dy- namic metamorphism, controlled magmatic intrusion and deposits （mineralization） distribution. Magma ac- tivities for mineralization bring a lot of metallogenic material and controlled the mineralization type of the fornix area.
