摘　　要：四道沟金矿床赋存于辽河群盖县组变质砂岩的互层带中,并受褶皱和断裂构造控制。文中从矿床地质特征、成矿地质条件和矿床地球化学等方面对该矿床进行了分析,指出区域变质作用和岩浆活动对成矿提供了有利的条件;盖县组中部岩性段的厚层状和薄层状变质砂岩的互层带是成矿最有利的围岩;在F2断裂与F3断裂之间,并靠近F3断裂附近是成矿有利场所;金矿化与黄铁矿化和硅化等类型热液蚀变关系密切。Sidaogou gold deposit occurred in the interbeded zone of Gaixian formation metasandstones of Liaohe group and was controlled by faults as well as folds. The paper analyzed the deposit in the aspects of geological features, ore-controlling conditions as well as geochemistry. It was put forward that the regional metamorphism and later magmatic activity provided favorable conditions for the deposit＇s formation; the interbedded zone between thick bedded and thin bedded sandstones of Gaixian formation was the favorable wall rocks for the deposit＇ s formation ; and the ad- jacent parts of fault F3 between F2 and F3 was the favorable location for the orebodies. There was an intimate spatial relationship between gold mineralization and pyritization or sericitization etc. wall rock alterations.
