摘要
斑岩型银铅锌矿床世界上并不多见,目前我国典型斑岩型银铅锌矿床仅冷水坑一处。笔者通过对冷水坑斑岩型银铅锌矿床的流体包裹体地球化学、稳定同位素地球化学研究,结合岩相学研究、激光拉曼探针(LRM)和扫描电镜/能谱(SEM/EDS)测试,揭示了冷水坑斑岩型银铅锌矿床成矿流体特征及演化过程,并进一步探讨了成矿物质来源和矿床成矿机制。研究表明,冷水坑矿床成矿流体及主要成矿元素(硫)来自于斑岩系统,大气水在整个成矿过程中均有不同程度的参与。
The porphyry Ag-Pb-Zn deposits are relatively rare in the world. In China, Lengshuikeng is the only deposit of this type. Based on a study of the Lengshuikeng porphyry Ag-Pb-Zn deposit in such aspects as its fluid inclusion geochemistry and stable isotope geochemistry in combination with lithologic investigation, Raman probe （LRM） and scanning electron microscopy / energy （SEM / EDS） analysis, the authors revealed characteristics of the ore-forming fluid and the evolutionary process in this deposit. The ore-forming material sources and the ore-forming mechanism were also studied. The result shows that the ore-forming fluid and the main ore-forming element （S） were derived from the porphyry system, and atmospheric water participated to some extent in the en-tire ore-forming process.
