| Abstract | No. 22 ore of Dafulou deposit was systematically analyzed for sulfur isotopes. The results show that the δ 34S values of sulfide minerals, ranging from −0.154 to +0.218% and with an average value of +0.114 1%, are mostly positive and characterized by rich sulfur (S) content. This suggests that the sulfur of the Dafulou ore deposit is derived from magma and relates to the Longxianggai concealed granite, which points to the important role of magma during mineralization and implyies the product of the active continental margin. By comparison between the Dafulou and the Kengma tin deposit, significant differences exist in the sulfur isotope composition. In the Kengma deposit, the sulfur isotope composition is characterized by the high negative value, which is different from the Dafulou tin-polymetallic deposit. The difference of the enrichment and fractionation of the sulfur isotope is the synthesized result of the metallogenic conditions. It also has the difference in the metallogenic environment and metallogenic characteristics of the deposit in the same ore belt. |
