Silver and sulfosalt minerals in tungsten deposits, South China

Abstract

Silver occurs in South China wolframite-quartz veins in three forms: (1) as micro inclusions of Ag2S and AgBiS2, (2) as argentite and matildite as a result of exsolution from galena and (3) as Ag-bearing sulfosalts and independent silver minerals.

According to mineral assemblages the Ag-bearing tungsten deposits are classified as two types: (1) Ag-bearing W-Bi deposits in eastern Nanling, where gustavite has been found and (2) Ag-bearing W-Sn(Sb) deposits which are mainly distributed in western Nanling. The authors consider that the enrichment of silver and sulfosalt minerals in the lower parts of pneumato-hypothermal tungsten deposits is the result of reversed vertical zoning caused by high concentrations of F and S in the ore-forming fluids.
