The mineral chemistry, trace elements and Sr-Nd isotopic geochemistry of different types of deep-seated inclusions indicate that Group Ⅰinclusions in western Shaudong could be the relicts of high degree of partial melting of the mantle-derived peridotites and then subjected to mantle metasomatism; the dunite and harzburgite in Group Ⅱ inclusions could be resulted from the metasomatism of silica-rich melts in the upper mantle; the olivine-pyroxenite and pyroxenite in Group Ⅱ and Group Ⅲ inclusions could be magmatic cumulates derived from magma underplating in the upper mantle.

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.
