| 摘 要： | 本文根据银山矿床成矿特征及其与邻区矿床的对比,论证了在该矿新发现的一种成矿作用──构造动力热液成矿作用;提出矿床的火山-岩浆热液成矿作用与石英斑岩岩浆阶段关系更为密切,形成内带为斑岩型Cu-Au矿体和外带为脉型Cu(Au)、CuPbZn、PbZnAg矿体的成矿系列。根据这两种成矿作用的时空关系,指出银山矿床是构造动力作用热液与火山-岩浆热液双重耦合成矿作用的产物,这一新的认识对指导找矿具有重要意义。

| Abstract: | By comparing with neighbouring area tectonic dynamic hydrothermal fluid,a new ore forming prosess discovered in Yinshan Cu-An mullti-metal deposit is demonstrated in this paper. Volcanic-magmatic hydrotermal metallogeny is closely related to quartz porphyre magma with porphyre type of Cu-An ore bedies formed at inner contact zone and vein type of on(Au),Cu, Ph,Zn amdpb,Zn,Ag ore bodies at the outer contact zone. According to the temporal and spital relation of the type of ore body it is concluded that this ore deposit is the product of coupling of tectonic dynamic hydrofhermal fluid and volcanic-magmatic hydrothermal fluid. The new thinking could be significant to further ore prospecting. |
