摘　　要：研究区位于辽吉古裂谷带上,鸭绿江成矿带西南段。行政区划位于吉东南辽东地区。区域岩浆活动以印支—燕山期为主[1]。区内近东西向构造形成较早,比较强烈,构成本区构造格架。断裂集中区,特别是不同方向断裂交汇区域,易于产出金矿体和多金属矿体;区域上铜(锌)、金、黄铁矿矿床严格受层位控制[7]。The study area is located in the rift valley alternating with Liaoning Province and Jilin Province, the Yalu River metallogenic belt southwest section Administrative districts is located in southeast part of Jilin Province and East Liaoning Area.
