The δ〓S value of pyrite, sphelerite and arsonopyrite is in the range of 4. 0‰ and -4. 2‰ with the highest frequency occurring around zero, indicating a uniformed sulfur source. The large variation and mainly negative values (0.2‰～-11. 3‰) of δ〓S for stibnite could be interpreted by isotope fractionation. The carbon isotopic characteristics exhibit a mixing nature of magmatic carbon and organic carbon.
