     By means of optical microscope, systems analysis the texture and structure, morpho- logical characteristics anf features of disseminated of copper sulfides and gangue minerals. The main copper sulfides is covellite and anilite. By electron probe, analysis of the copper sulfides content of various elements, especially the major elements of Cu / S ratio of vertical variation is that drilling shallow is no obvious rule, and with the depth increasing , Cu / S ratio decreases gradually, and finally closes to 1.3. Copper mineralization have two factors： one is that limited impact on the volcanic edifice temperature did not change the copper sul- fides mineral assemblage, and affects only the copper sulfides Cu / S ratio distribution, showing more away from the volcanic edifice of Cu / S ratio the higher; the other is The high oxygen fugacity is an important condition for stable copper sulfides. The oxygen fugacity of the vertical from top to bottom first high oxygen fugacity, and gradually decreases with increasing depth, the last increase of high oxygen fugacity. Cu / S ratio variation provides important information on the mineralization for deep prospecting of Zijinshan copper ore in the future.
