| 摘 要： | 近年来勘查成果表明，青海东昆仑东段是一个以金为主的成矿聚集区，各矿区含矿层位不尽相同。通过对不同的含矿地层和岩体地球化学微量元素分析，认为地层并不能提供金矿成矿物质的来源。区域变质作用造成了金的活化迁移，后期的岩浆热液作用对金的富集具有重要的作用。

| Abstract: | In recent years,survey results indicate that there are many gold deposits in the east segment of the East Kunlun,which are located within the different ore-bearing strata.Based on the analysis of the geochemistry of trace elements of various strata and volcanic rocks,it is confirmed that the stratum is not the material source of gold mineralization,and that the regional metamorphism leads to the activation and migration of gold,and that magmatic hydrothermal fluid plays an important role in gold enrichment ... |
