摘　　要：龙脖河地区地层系统是一套由印支（ 青藏滇） 板块俯冲碰撞扬子板块造山时形成的混杂的构造复合地质体。其主体地层应为二叠纪的泥砂质－ 火山岩建造，混有元古宙岩块和三叠纪岩块。其成矿作用主要受二叠纪火山岩相及火山机构控制。采用造山带区域地层学———非史密斯地层学方法来恢复其原始状态，有利于查明成矿作用、矿体产出规律。Strata in the Longbohe area are the complex formed in the collision of Indosinian plate and Yangtze plate. The lithology of strata is mainly Permian argilic-arenaceous-volcanic sedimentary formation with mixing of Proterozoic and Triassic rocks. The metallization is controlled by the Permian volcanic lithofacies and volcanic edifice. The adoption of regional petrographic analysis of orogeny is conducive to the restoration of the primary state. It is the best way for determination of metallogenic regularities and for the breakthrough in prospecting.
