Geochemical behaviors of major and trace elements in the weathering process of the ore-bearing porphyry within the Chengmenshan copper deposit were systematically studied by using the open pit system. The results show that the ore-bearing porphyry has experienced two evident cycles of weathering, and the process of weathering mainly finds expression in the hydrolysis of aluminosilicate minerals and hydration, the leaching of large quantities of Ca, Mg, Na, K and other elements(the leaching amount of Ca, Mg and Na up to 80%), and the preservation of Si, Al, Ti and Fe in the weathered layer.  oft-com:office:office" />
