The S isotope compositions of sulfide minerals from periods A and B that were determined during this study and those previously reported by Yang et al.（2009）are given in Table 6.These samples haveδ34SV-CDT values of4.5‰–13.2‰，consisting of 11.2‰–13.2‰of sphalerite，11.2‰–12.7‰of pyrite，9.9‰of galena.Period A galena，sphalerite，and pyrite yielded a narrow range of positiveδ34SV-CDT values（9.9‰–13.2‰）that are little higher than the range of the period B samples（7.2‰–12.1‰；Fig.16b）.In period B，sphalerite from the deposit yields the highestδ34S V-CDT values of 9.1‰–12.1‰，followed by galena and sulfosalt minerals（boulangerite）with 9.4‰and8.7‰–11.2‰in pyrite，while stibnite yielding the lowestδ34S values of 4.5‰–9.2%（Fig.16b）.However，the Sisotope compositions of samples from the Zhaxikang deposit differ from those of other Sb-Au deposits in this area，which have values between~5‰and 0‰（Fig.16a）.The S isotope composition of south Tibet sedimentary rocks is relatively higher than the period B that is around10‰（Fig.16a）.
