摘要
根据碰撞带不同单元按构造一岩石地层划分原则，分出有序和无序两套地层岩石组合，分属两个不同的构造一火山活动带，碰撞造山与韧性剪切带强时空耦合．碰撞带两侧岛弧火山岩和带内碰撞花岗岩特征和成岩成矿时代、地球化学省等表明其较特殊的碰撞造山和陆内造山成盆多阶段演化特点。与碰撞造山有关的金铜矿分七种成因类型。现划10个成矿区带分属两个古陆边缘成矿系统，金矿成矿可分为五个阶段。金铜矿成带分布与碰撞造山演化有关，空间上北部铜矿带，南部金矿带，为今后进一步找矿指明了方向，提出了具体靶区。
According to tectono-stratigraphical division principle, different units in foe collision zone are divided into order and disorder two types of stratum-rock associations, which belong to two kinds of different tectono-volcanic activity belts. The collision orogeny and ductile shear zone have a strong space-time coupling. Based on the island arc-bearing volcanic rock on both sides of the collision zone, time of ore-forming and rock-forming, characteristics of collision granit, geochemical province, special multistage collision omgeny and intracontinental orogeny basin--forming developed features have been found. Gold and copper deposits, with the relation to the collision orogeny, are divided into seven genetic types. The ten metallogenic zones are departed into two kinds of oreforming system of paleo-continental margin. Metallogenesis of gild deposits can be' classified into l'ive stages. Gold and coPPer dePOsits are distributed in belts with the relation to the development ofcollision orogeny. The distribution of coPPer deposits in the north and gold deposits in the south of the collision zone can direct the prospecting for gold and copper deposits. The actual targets are putforward.
