富源东铺中低温热液、叠加金矿

东铺金矿成矿物质来源于海底火山喷流作用及壳源含金热流的再循环。边缘深大断裂控盆和产生的多期表部脆性变形，除使区域上古生界地层和早期形成的(火山喷发不整合)结构面卷入构造变形，形成不同规模、不同形状、不同性质的剪切透镜体、断层三角块和变形面理外，同时由于深部与浅表部构造的互通，使区内形成含金高热流场，导致不同层次的含金热流沿性质已发生改变的华力西不整合面(带)成矿与控矿。中低温热液交代充填，叠加冷水含金矿液次生淋漓作用，构成了区内独具特色的二元矿床类型。

THE MEDIUM-LOW T HYDROTHERMAL AND SUPERIMPASED GOLD DEPOSIT OF DONGPU

The metallogenetic material of Dongpu Au deposit is derived from the submarine volcanic eruption and crust-derived Au-bearing hydrothermal fluid. The deep fault and surface deformation form the channel between deep and surface structures. And the Au-bearing hydrothermal fluid on various levels forms the ore deposit along the reformed Variscan unconformable contact. The special binary metallogenesis in this area is the medium-low T hydrothermal metasomatism-filling and the superimpased cold water secondary leaching of Au-bearing fluid.
