广西博白县六林金多金属矿区地质特征与矿床成因浅析

Geological characteristics and genesis of Liulin gold polymetallic ore area, Bobai County, Guangxi Province

六林矿区位于云开台隆与博白拗陷的接合部位的西南段,属于博白~岑溪铅锌钨金银多金属成矿带西南段。矿区出露地层以泥盆系为主,其次为奥陶系沿断裂呈断块产出。矿区构造是以NE向断裂为主。矿区内金多金属矿体多产于NE向断裂中,受断层严格控制。矿区的矿床成因类型属中低温热液矿床。通过对该类矿床成因进行分析,以期对该区寻找此类型矿床提供有益参考。

Liulin Mining Area is located in the southwest part of the junction of Yunkai platform uplift and Bobai depression,which belongs to the southwest part of Bobai Cenxi lead zinc tungsten gold silver polymetallic metallogenic belt.The main exposed strata in the mine area are Devonian system,followed by Ordovician system along the fault block.The structure of the mining area is dominated by NE faults.The gold polymetallic ore bodies in the mining area are mostly distributed in NE faults,which are strictly controlled by faults.The genetic type of the deposit in the mining area belongs to the middle and low temperature hydrothermal deposit.Through the analysis of the genesis of this type of deposit,we hope to provide a useful reference for the exploration of this type of deposit in this area.
