摘要
扬子地台北缘大多数金矿床集中在裂谷系古陆隆起内外接触处，经历了复杂的地壳构造演化，形成新的金矿类型和矿化组合，具多源性，以深源为主，浅源次之，再次是陆源，控矿构造包含同生构造与封闭聚矿盆地等多种成矿作用的叠加。
Most of the large gold and polymetal deposits distributed in the north margin of the Yangtze platform located in the nuclei of old rift system.With complex geological and structural evolution,new gold deposit types and mineralization assemblages of polymetal were formed.Ore forming materies are poly sources,mainly from deep,secondly,from shallow and continental.Ore control stractures are complex parts of some tectonic styles such as syngentic structures and enclosed ore gathering basin.
