通过对蛇屋山金矿氢氧碳硫同位素地球化学研究,结合矿床地质特征分析,探讨了主要载金矿物的形成条件与氢氧碳硫及成矿流体的来源,指出内生成矿期的成矿流体为大气降水深循环并与海相碳酸盐发生了广泛的水岩交换,形成了原生微细浸染型金矿化,其后在表生条件下金进一步富集而形成了金矿床中粘土质矿石主矿层。 Through the study on the isotope geochemical study of carbon, oxygen and sulfur in the Snake House Mountain gold deposit and the analysis of the geological characteristics of the deposit, the formation conditions of the major gold-bearing minerals and the sources of the hydrocarbon-oxygen and sulfur-bearing fluids and ore-forming fluids are discussed. The fluid is a deep circulation of atmospheric precipitation and extensive water-rock exchange occurs with the marine carbonate, forming a native finely disseminated gold mineralization, followed by further enrichment of gold under epigenetic conditions to form a medium- Ore main ore.
