This paper reports Zn isotope compositions of sphalerites and associated pyrites from the Xinqiao and the Fenghuangshan skarn type sulfide deposits in Anhui Province.  Sphalerite pyrite fractionation factor is also discussed. Based on results obtained by previous researches, this paper discusses the application of Zn isotope system to the study of ore deposits.  It is found that Zn isotope can be used to trace the fluid evolution and the variation of source area.  During the fluid evolution in a hydrothermal fluid system, the fluid became enriched in heavier Zn isotope with the precipitation of minerals.  Zn isotope composition of late stage minerals is heavier than that of early stage minerals.
