贵州水银洞金矿是黔西南地区一个重要的超大型卡林型金矿,也是国内外少见的一个“高品位、大吨位”卡林型金矿。为了探讨矿床的物质来源问题,在前人研究资料的基础上,对矿床各个中段不同矿体的硫化物、碳酸盐矿物进行了系统采样,进行了S、C、O同位素的测试分析。同时对前人所作的放射性同位素Pb研究成果进行了整理分析。研究表明,水银洞金矿的成矿物质来源具有多源性。结合区域成矿地质背景,认为区域上卡林型金矿的物质来源具有壳幔结合的特点。
Guizhou Shuiyindong Gold Mine is an important super-large-scale Carlin-type gold mine in southwestern Guizhou and a rare “high-grade, large-tonnage” Carlin-type gold mine at home and abroad. In order to discuss the material source of the deposit, based on the previous research data, the sulfide and carbonate minerals of different ore bodies in various middle stages of the deposit were systematically sampled and the isotopes of S, C and O were tested. At the same time, the predecessors made radioisotope Pb research results were analyzed. The research shows that the source of metallogenic material in Shuiyindong gold deposit is multi-sourced. Combined with regional metallogenic geological background, it is considered that the source of Carlin-type gold deposits in the area has the characteristics of crust-mantle combination.
