金石嶂矿区外围银多金属矿地质特征与找矿标志

Geological Features and Ore Criteria for the Jinshizhang Ag-Polymetallic Deposit in Guangdong

广东金石嶂矿区大地构造位置属华南褶皱系加里东隆起区,处于NE向河源深断裂带与EW向贵东大断裂交接部位南西侧的新丰-连平中新生代火山岩喷发带内。该文对矿区地层特征、构造特征、岩浆岩、围岩蚀变及变质作用进行分析,对矿体地质特征、成因及找矿标志进行了综合研究。其成果对矿区的找矿工作具有重要的参考意义。

The Jinshizhang Ag-polymetallic deposit occurs in the Mesozoic-Cenozoic Xinleng-Lianping volcanic rock zone on the southwest side of the intersection of the NE-trending Heyuan deep fracture zone with the EW-trending Guidong fracture zone. This paper deal with geology, structure, magmatic rock, wallrock alteration and metamorphism, ore ~enesis and ore criteria of the Ag-polymetallic deposit.
