Abstract
Based on the analysis and study of mineral composition, structure, and major and trace elements, this paper deals with element geochemical characteristics and transformation from primary ore into oxidized ore in the Erzhe gold deposit, Sichuan. Some grounds are provided to constrain the transformation of primary ore to oxidized ore.
