The existing phase of copper in supergenic medium is very important to the development of supergenic anomaly. On the base of analysis and study on seven copper's existing phase in soil and lacustrine sediment, it is proved that the copper's existing phase are different between each layer in soil vertical section, and the differences change with the different location of soil in near mineral deposit and over ore body. The distributing characteristics of copper's existing phase depends on some factors, such as geographical landscape condition of ore region, soil types of structure, physical and chemical coefficient of soil environment and the copper's supergenic geochemical nature, and so on. The further study on the controling factors is important basis of researching the formation mechanism of supergenic anomaly and evaluating it.
