摘要: 柏杖子金矿系辽西凌源地区重要的岩浆热液型金矿.矿区出露的地层主要为中元古代长城系大红峪组，其次为太古宙建平群变质岩系.长城系大红峪组为金矿的主要容矿围岩，太古宙建平群变质岩系为金矿的矿源层.柏杖子岩体为区域上大柱子岩体的分支岩体，柏杖子岩体由地壳深部上侵的过程中萃取了建平群变质岩系中的成矿物质，沿北北东-北东方向上侵并在长城系大红峪组地层中形成金矿体.通过总结、分析成矿的主要过程，建立了柏杖子金矿的成矿模式.Abstract: The Baizhangzi gold deposit is an important magmatic hydrothermal type of gold deposit in Lingyuan, Western Liaoning Province. The outcrop in the orefield is dominated by Dahongyu Formation of Changcheng System, which serves as the host rocks. The metamorphic series of Archean Jianping Group is the main resource bed of Baizhangzi gold deposit. The Baizhangzi ore body is the branch of Dazhangzi intrusive rocks, which intruded upward from deep crust and extracted oreforming material from Jianping Group, finally formed gold orebody in Dahongyu Formation. With analysis of the ore-forming process, the metallogenic model of Baizhang gold deposit is set up.
