| 摘 要： | 娄家店金矿床位于辽西凌源—北票金成矿带北东部,矿区内已发现5条金矿脉,均严格受断裂构造控制,矿石类型为含金石英脉型和蚀变岩型,硅化、黄铁矿化围岩蚀变与金成矿关系密切,成矿阶段可划分为3个阶段,其中石英-多金属硫化物阶段为主要成矿阶段。综合分析表明,娄家店金矿床为受太古宇建平群小塔子沟组地层、燕山期二长花岗岩及鸡冠山断裂次级断裂控制的复合成因热液型金矿床。

| Abstract: | Loujiadian Gold Deposit is located in the northeastern part of Lingyuan-Beipiao gold belt sitting in West Liaoning.There are 5 gold ore veins in the mining area,all strictly controlled by fracture structures.The ore types are mainly gold-bearing quartz vein type and alteration type.Wall rock alteration like silicification and pyritization is closely related to mineralization.The metallogenic stages can be divided into 3 stages.Among them the quartz-polymetallic sulphide stage is the main metallogenic stage.Comprehensive analysis shows that Loujiadian Gold Deposit is a multi-genesis hydrothermal gold deposit controlled by the strata of Archean Eonothem Jianping Group Xiaotazigou Formation,Yanshanian monzonitic granite and secondary fault of Jiguanshan fault. |
