Geochemical abnormality is the basic means for evaluating mineralization prospect and type. Based on the method and principle of the tracing the source of mineralization material, this study applies sulfur isotope into geochemical abnormity. The research on sulfur isotopic compositions of Cu-mineralized bodies in the Wunugetushan and Kenshan trial areas suggest the same origin of sulfur for both areas, indicating that sulfur isotope can be employed to judge the origin of geochemical abnormity. Comparison study shows that the sulfur isotope compositions in the Kenshan are higher than those in the Wunugetushan, and this implies the Cu abnormity maybe result from hydrothermal effect at the late stage. The study suggests that geological exploration and arrangement in this area should focus on hydrothermal deposits.
