摘　　要：吉林省梅河口市张家沟区金矿床矿体位于槽台过渡带靠近台区一侧,且基底岩系金丰度值高。区域构造结点有隐爆角砾岩筒存在,岩筒内有硫化物-石英细脉、网脉出现。找矿重点区域应为靠近烟筒桥子一侧的火山角砾岩筒之中。Zhangjiagou gold deposit of Meihekou City, Jilin Province is located in the platform of trough-platforms transition zone,the high Au abundance hosts in basement rocks. Cryptoexplosive breccia cylinder exists in regional structure nodes, there are sulifde-ifne quartz vein, the network veins in the rock formation. The key prospecting area should be in the volcanic breccia near Yancongqiaozi.
