Geochemical Abnormality is the basic resource of the evaluation of mineralization prospect and mineralization type. Based on the method and principle of the tracing of the source of mineralization material from the stable isotope, and set the composition of Sulfur isotope in the surrounding rock and mineralization body of the different drill holes which from two testing regions named Wunugetushan and Kenshan as our researching target, otherwise we bring Sulfur isotopic indexes into the researching of the cause of geochemical abnormality. As our prediction, we find some obvious characters as follow. First the related source of Sulfur element in the Cu mineralization and Cu abnormality from different testing regions are primarily unanimous, which indicates that the application of the composition of Sulfur isotope in evaluating the cause of geochemical abnormality is feasible. Second the Sulfur isotopic value in Kenshan testing region is higher than Wunugetushan that may be caused by the later period hydrothermal fluids in these area，So some geological exploration and arrangement should be forced on hydrothermal deposit.
