| 摘 要： | 通过对川滇黔相邻区热液或热液改造型Cu,Pb,Zn,Au,Ag矿床的地质特征,特别是峨眉火成岩省与该类矿床的成因关系的讨论认为：峨眉地幔柱活动是扬子地台西南缘最大的一次构造—岩浆热事件,对该区Au,Ag,Pb,Zn,Hg,Te,Sb,Se等热液—热液改造型矿床的成矿起着非常重要的控制作用。除可能提供了少量的成矿物质外,更重要的是引起了强烈的壳幔相互作用,造成大区域尺度的异常高热流场,对成矿流体的形成、循环、演化起了重要的促进作用,为成矿、特别是富矿的形成提供了充足的物质条件和热动力条件。

| Abstract: | This article introduces the geologic features of hot liquid or hot liquid reforming ore deposits of Cu, Pb, Zn, Au and Ag in the contiguous region between Sichuan, Yunnan and Guizhou Provinces, and mainly discusses the relation between the formation of this kind of ore deposit and Emei igneous province. The author thinks that, Activity of Emei mantle plume is the most serious tectonic and magma-heat event on the southwest edge of Yangtzi platform and plays an important role in the ore formation of hot liquid-hot liquid reforming ore deposit of Au, Ag, Zn, Hg, Te, Sb, Se etc in that area. Besides providing a small amount of ore-forming material, the more important is that it causes violent interaction of crust and mantle, forming extremely hot stream field in a large area, accelerating the formation, circulation and evolution of crust ore-forming fluid, and providing sufficient material condition and thermadynamic condition for ore formation, especially for the formation of rich ore. |
