| 摘 要： | 银山铜铅锌金银矿床住于江西省德兴市乐德成矿带中段，是我国南方规模巨大的铜铅锌金银矿化集中区。区内构造复杂、岩浆活动频繁，具有独特的成矿环境和有利的区域成矿背景。本文主要研究了银山矿床成矿流体种类、成矿温度、流体盐度、成矿物质来源和成矿机理。根据包裹体均一温度、盐度、成分和氢氧同位素等资料，推断本区成矿流体早期以岩浆热液为主，与铜金矿化关系密切。岩浆热液演化过程中与富含有机质的大气降水不断混合，由于有机质的作用，带来了从围岩中活化、萃取的有用元素，晚期铅锌银矿化与富含有机质的热液流体关系密切。研究表明流体的沸腾对矿质沉淀意义有限．而多种流体的混合在成矿过程中起了重要作用．其中有机流体在成矿中的作用不容忽视。

| Abstract: | The Yinshan Cu-Pb-Zn-Au-Ag deposit is located in the Dexing county of Jiangxi province and at the middle oi the Le-De mineralization belt, which is a huge polymetallic metallogenic concentration region in South China. The tectonics and magma intrusions are complicated at this region. They have a special environments and advantageous regional background for ore-forming. This work takes aim at the types, temperature, salinity, matter source of ore-forming fluid and the mechanism of mineralization. It is based on the data the homogenization temperature, salinity of fluid inclusions. It is suggested that the early stage of ore-forming fluid is manly magmatic solution. There have a close relationship with Cu-Au mineralization. Magmatic solution were mixing with atmospheric precipitation in the evolution. Atmosphric precipitation are rich in organic materials and bring with activationed useful elements. Late stage Pb-Zn-Ag mineralization has close relationship with the organic fluids. It is suggested that fluids boiling are not main reason of metal precipitation. The mixing between magmatic solution and meteoric water and organic fluids are very important constrants on the process of mineralization. |
