摘　　要：广西六星铅锌金银多金属矿床是近年来大明山地区昆仑关花岗岩体外围找矿的典型成果之一。矿床赋存于中上寒武统黄洞口组碎屑岩建造中,成矿与南丹—昆仑关深大断裂及昆仑关花岗岩体密切相关,岩体外围的放射状断裂直接控制着矿体的就位产出。矿床成因类型属于热液充填型脉状矿床,热液期形成了Pb-Zn-Ag等金属元素,表生期的次生富集作用形成了Au。文章对上述特征进行研究,并探讨了矿床的找矿标志,以期对区内多金属矿产勘查有所帮助。The discovery of the Liuxing Pb - Zn - Au - Ag polymetallic deposit is one of typical prospecting achievements in the surrounding areas of the Kunlunguan granite rockmass in Guangxi Zhuang Autonomous Region. The deposit is located within the elastic rocks of Middle - Upper Cambrian Huangdongkou Formation. The Pb - Zn - Au - Ag mineralization has a close relationship with the deep Nandan - Kunlunguan fault and Kunlunguan granite rockmass, and orebodies are directly controlled by the radiant fractures at the periphery of rockmass. The deposit genesis belongs to the hydrothermal vein type deposit, the Pb, Zn, Ag and other metallic elements are enriched in the hydrotherrnal stage, while the Au is enriched in the supergene stage. This paper summarized the geological charac- teristics of the deposit and discusses the prospecting criteria which can guide the exploration of this type polymetallic deposits in this region.
