衡阳黑石砣铜多金属矿床地质特征、成因分析及找矿标志

黑石砣铜多金属矿床是近些年在衡阳盆地北缘发现的富含Cu、Pb、Fe等多种有色金属的中型规模矿床。矿床产于硅化破碎带中,由12个铜矿体、3个铅矿体和7个铁矿体构成。文章在详细阐述矿床区域地质背景和地质特征的基础上,厘定矿床成因、总结控矿因素和找矿标志,认为该矿床是低温热液充填—交代型矿床,矿体完全受断层F_1控制,硅化、重晶石化、钾化、黄铁矿化是该矿床重要的找矿标志。

Geological characteristics, genetic analysis and ore-prospecting criteria of Heishituo copper polymetallic deposit, Hengyang

The Heishituo copper polymetallic deposit is a medium-sized deposit rich in Cu, Pb, Fe and other nonferrous metals discovered in the northern margin of Hengyang basin in recent years.The deposit is formed by 12 copper ore bodies, 3 lead ore bodies and 7 iron ore bodies.In detail in this paper ore deposit, on the basis of regional geological background and geological characteristics of ore deposit origin, summarizes ore-controlling factors and prospecting marks, thinks that the deposit is low temperature hydrothermal filling and metasomatic type of ore deposits, orebodies are controlled by fault F1, completely silicide, barite, potassium and pyritization are important prospecting marks of the ore deposit.
