摘　　要：四道沟金矿床是辽宁省开发较早的金矿之一,现已进入严重资源危机状态。金矿化以含金黄铁矿为特征,产出于盖县组变质砂岩段厚层状变质砂岩、薄层状变质砂岩和石墨化片岩的互层带中,矿体产状与地层一致;金矿体呈透镜状、脉状,产状受北东向褶皱轴及层间破碎带控制;中生代脉岩与矿体相互穿切。矿石分带特征明显,矿床属沉积变质—热液叠加型成因。成矿地质条件分析结果表明,在矿床深部及外围具有较大找矿潜力。Sidaogou gold deposit is one of the oldest gold deposit in Liaoning province and it faces a severe resource risk now. The gold metallogeny is characterized by auriferous pyrite and occurred in the alternating layer of heavy-layer metasandstone, flaggy metasandstone and graphitization schist. The attitude of orebody accords with the strata, and is controlled by the axis of folding and interlamination broken belt. The gold orebodys like lens and veins, and are cut by the Mesozoic veins. The deposit belongs to diagenetic metamorphism-hydrothermal fluid superposition type. The analysis on metallogenic conditions revealed that there are great ore prospecting potentials in the deep part and periphery.
