This paper deals with the method of applying XPS to the study of compositional characteristics and modes of occurrence of geogas current and presents the results of the research conducted over the Zouping concealed copper deposit, Shandong Province. The results show that some characteristic compnents in geogas current are related to copper deposits at depth, and some components have to do with surficial soil. Such elements as Au、Ag、Cu and Pb are present as simple substances, sulfides and oxides. There also exists An of negative valence sstate in some unknown sulfides.
