摘要
In this paper, the authors reported the sulfur isotope compositions of major ore minerals (Pyrite, sphalerite and galena) of primary ore body and discussed the source of ore-forming fluid. The result showed that values of δ34S were concentrated in the range from 13‰ to 17‰, which were different from the mantle-derived sulfur which values are near 0‰ and were close to those of different time sulfates series such as gypsum and barite with the values of δ34S being about 15‰ in the ore field. It suggests that sulfur in ore-forming mainly came from thermo-chemical sulfate reduction (TSR) in gypsum-salt zone of different time carbonate formations in this area.
