摘要: 辽南猫岭金矿床是低品位细脉浸染型金矿床,矿体为含金石英细脉和含金毒砂-黄铁矿化绢云千枚岩。本文研究了该矿区地质特征、矿床地质特征及矿化的物质来源,认为其成因与岩浆活动有关。本文在此基础上建立了猫岭细脉浸染型金矿床的成矿模式。Abstract: Maoling gold deposit,located in the southwest of Liaodong Peninsula, discovered in 1985, is a giant veinlet-disseminated ore with low grade. The ore bodies are auriferous quartz veinlets and-arsenopyritized-pyritized sericite phyllite or schist. Au grade ranges from 3 to 5g/t. The country rock is the second member of Gaixian formation. Magmatic activities were common in the area.
