摘　　要：该文根据江西银山金铜多金属矿床特征及与邻区矿床的对比，论证了构造动力热液成矿作用在银山矿床形成过程中的意义；提出了矿区火山岩浆热液成矿作用的新认识，即：火山岩浆热液成矿与石英斑岩岩浆演化阶段关系更为密切，矿化与深部大斑岩体有关，形成内带斑岩型Ａｕ、Ｃｕ矿，外带脉型Ａｕ、Ｃｕ、Ｐｂ，Ｚｎ、Ａｇ矿的成矿系列。根据两种成矿作用之间的相互时空关系，作者认为银山矿床是构造动力热液与火山岩浆热液双重藕合成矿的产物。According to features of deposit and contrast with neighbouring depo-sits,significance of tectonodynamo-hydrothermal mineralization in thecourse of Yinshan ore deposit formation was discussed;New recognitionof vocano-magmatic hydrothermal mineralization was proposed,namely,volcano-magmatic hydrothermal mineralization was closely related to themagmatic evolution stage of quartz porphyry:mineralization related todeep-level large porphyry body,thus forminga mineralization series ofporphyry gold-copper mineralization in inner zone and vein-typegold-copperzinc-silver mineralization in outer zone On the basis ofthe temporal-spatial relationship between two mineralizations,it isconcluded that the formation of Yinshan ore deposit was attributed to double coupling mineralization tectonodynamic and volcano-magm-atic hydrothermal solution.
