According to the oxidation intensity of ore‐hosting sandstone, the interlayer oxidation zone of the Shihongtan sandstone‐type uranium deposit in the Turpan‐Hami basin can be divided into 4 geochemical subzones, namely, intensely‐oxidized, weakly‐oxidized, redox and unoxidized primary subzones. The elemental geochemical characteristics of the four subzones have been studied in detail, and the results show that U, together with other elements such as Re, Mo, Se, Sr, S, REE, C organic etc., is enriched in the redox subzone. Re and U have similar geochemical properties in the reduction‐oxidation process. The geochemical properties of Mo and Se are similar to those of U in the reduction condition, but different from those of U in the oxidation condition. It is proposed that the ore‐hosting layers can provide a curtain mount of uranium for uranium mineralization.
