The interlayer oxidized zone and the concentration of uranium has the typical characters of low temperature geochemical processes. Interlayer oxidized zone can be defined from the bedrock to horizon C under hypergene weathering by such parameters as chemical metamorphosing、index of chemical weathering and index of mineral chemical differentiation.(2)Major elements can be divided into sensitive group、 active、 weak active and inert groups according to chemical metamorphosing parameter and fractional migration potential. For major elements of multivalent in the active group( Fe_2O_3、 FeO) and U, the migration and concentration trend in interlayer oxidized zone is apparent.
