四川省梭罗沟金矿床与日拉金矿床辉锑矿地质特征对比研究.

Suoluogou Gold Deposit is the largest gold deposit identified in the Ganzi - Litang gold belt. Stibnite is one of the associated minerals of the deposit, and no relevant research work has been carried out. Based on a detailed investigation of the field geological characteristics of the stibnite, this study conducted a gold content test and in-situ LA - MC-ICP-MS analysis of the single mineral of stibnite in the Suoluogou Gold Deposit and Rila Gold Deposit through petrographic and mineralogical observations. It was found that with similar ore section grades, the gold content of Suoluogou Gold Deposit is higher than that of Rila Gold Deposit, and pyrite is still the main gold-bearing mineral. The ore-forming materials are derived from highly homogeneous crust-derived metamorphic hydrothermal fluids. Based on the sulfur isotope characteristics of other deposits in the region, it is believed that most ore-forming hydrothermal fluids in the Ganzi - Litang gold belt mainly come from metamorphic hydrothermal fluids. The element correlation analy- sis found that As, Cu, Hg, Ag, Pb, Zn, Cr, and other elements has a positive correlation with Au. In addition to Au, As, and Sb elements, Cu can also be used as a feature element for geochemical prospecting in the region. [ABSTRACT FROM AUTHOR]
