| Abstract: | In wolframite-quartz veins of South China silver is in three forms:1. micro inclusions of Ag_2S and AgBiS_2, 2. argentite and matildite separatedfrom galena solid solution, 3. Ag-bearing sulphosalts and independent silverminerals. According to the mineral assemblages two Ag bearing tnngsten ore typesare classified: 1. Ag-bearing W-Bi ores in eastern Nanling, where gustavitehas been found, 2. Ag-bearing W-Sn Sb ores, which mainly exist in westernNanling. The authors consider that the enrichment of silver and sulfosalt mineralsin pneumato hydrothermal (high temperature) tungsten deposit was caused bythe vertical reverse precipitation zoning in tungsten ore veins due to theore forming fluid enriched in F and S, and resulting in the concentrationof silver at the lower part of the ore veins. |
