摘要
热液(水)系统铅锌矿成矿流体的研究,是矿床地球化学研究的重要课题之一。正确识别系统中流体包裹体特征,成矿流体来源、迁移及金属沉淀机制,是深刻理解热液铅锌矿形成演化的关键。文章系统总结了与VMS型铅锌矿成矿流体有关的流体包裹体岩相学特征、成分测试技术与方法、成矿流体形成与演化。以VMS型矿床的典型成矿模式为主线,分别讨论了成矿流体载体矿物的选择、流体包裹体均一温度和盐度、LA-ICP-MS的应用、流体包裹体成分及同位素成分分析,并给出了VMS型铅锌矿成矿流体研究方面今后的发展趋势。
The study of ore-forming fluid of lead-zinc ore in hydrothermal(water) system is one of the important subjects in the study of ore deposit geochemistry.The correct identification of fluid inclusion characteristics,ore-forming fluid origin,migration and metal precipitation mechanism is the key to understand the formation and evolution of hydrothermal lead-zinc deposits.On the basis of previous research results,this paper systematically summarized the petrographic characteristics of fluid inclusions,composition testing techniques and methods,and the formation and evolution of ore-forming fluids related to the ore-forming fluids of VMS-type lead-zinc ore deposits.Taking the typical metallogenic model of VMS type deposit as the main line,the selection of ore-forming fluid carrier minerals,homogenization temperature and salinity of fluid inclusions were discussed respectively.The application of LA-ICP-MS,the analysis of fluid inclusion composition and isotope composition,and the development trend of ore-forming fluid of VMS type lead-zinc ore were given in this paper.
