摘要
The Nongruri gold deposit located in the Riduo Town, Maizhokunggar County, Tibetan Autonomous Region, is an epithermal Au-Sb deposit firstly found in the eastern section of southern Gangdese metallogenic belt. Based on the results of field geological survey, and fluid inclusion measurements including petrography, homogenization temperature analysis, composition of liquid and vapor by laser Raman analysis (LRM) and daughter mineral by X-ray analysis (SEM/EDS), the characteristics, the evolution of ore-forming fluid and mechanism of Au precipitation were discussed in this paper.
