On the basis of studying the features of the Yimen Fengshan copper deposit, by applying diapir structure-petrographic mapping method, the ore-bearing-type diapir identification marks, material composition, diapiring type, internal structure, tectonic banding characteristics have been dissected. The main ore-bodies occur in the strong copper mineralizational gray silicified dolomitic cataclastic rock facie zone and copper mineralizational cataclastic dolomite facie zone. The mineral association of metal sulfides and ore structure also showed the horizontal zoning: chalcopyrite + bornite association, massive and stockwork structures→chalcopyrite + bornite + chalcocite(less) association, densely disseminated and vein structures→chalcopyrite +pyrite + bornite(less) association, small-vein and scattered point structures.
