摘要
本文总结MVT铅-锌矿床的最新地球化学研究方法及研究成果,包括δ18O、87Sr/86Sr、δ34S、206Pb/204Pb、Cl/Br、δ44Ca、同位素定年,以及利用地球化学参数所进行的数值模拟等。以这些方法的研究成果为依据,结合对白云石化作用和有机质在成矿系统中作用的分析,深入探讨了MVT铅-锌矿床的成矿系统,总结出一个与有机质密切相关的流体混合成矿假说。另外,强调了最新研究成果——金属硫化物和脉石矿物相异的流体包裹体成分,将在今后成矿系统的研究中发挥重要作用。
This paper summarized the latest geochemical research methods of MVT lead-zinc deposits,including δ18O,87Sr/86Sr,Cl/Br,δ34S,206Pb/204Pb,REE,MTE,δ44Ca,isotopic dating and numerical simulation of geochemistry parameters.On the basis of research results of these methods,analysis of the dolomitization and organic matter effects in metallogenic systems,we discussed in details about the metallogenic system of MVT lead-zinc deposits,and proposed a hypothesis of organic matter related fluid mixing metallogenic.Besides,we emphasized the latest research results of metallic sulfide and gangue sulfide＇s dissimilar compositions of fluid inclusion,which will be increasingly important in the future research.
