In this paper, trace elements of sulfide (241) in different ore bodies and different host rocks have been systematically determined by electron micro probe analysis. As a result, sulfide of the deposit has a high content of selenium, the average value is 0.045%, and the value of S/Se is average 829. The results suggest that sulfide of the deposit is formed at higher temperature and possess a feature of magmatic hydrothermalism. Ore body No.Ⅰ and No.Ⅲ have characteristics of different metallogenic environments and mineralization periods, which is of great significance for studying the ore genesis and selenium occurrence of the deposit.
