Abstract：The Qianjiadian sandstone-type uranium deposits is a large uranium deposits discovered in the Songliao Basin. The uranium deposits discovered mainly occur in the Lower Member of the Upper Cretaceous Yaojia Formation. The ore body is tabular and lenticular,mainly controlled by the interlayer oxidation zone. By testing and analyzing the main elements,trace elements and rare earth elements in the oxidation zone of the Qianjiadian sandstone-type uranium deposits(oxidation zone,transition zone and reduction zone),the results show that the geochemical characteristics of each zone vary greatly,where the interlayer oxidation zone can be zoned relatively accurately by Fe2O3,FeO,Al2O3,SiO2,Na2O and K2O and MgO and CaO have certain indication significance for zoning. From the oxidation zone to the transition zone,the trace elements that tend to be enriched are mainly radioactive elements(U),large ion lithophile elements(Li,Ba),chalcophile elements(Ni),high field strength elements(Nb,Ta),active variable valence elements(Mo),etc.,and LREE,MREE and HREE have different degrees of enrichment,reflecting the long water-rock interaction with large intensity. The significant difference of reducing indexes of organic carbon,St,and ωFe3+/ωFe2+ in different zones indicates that with the migration of oxygen-uranium containing water in the Yaojia Formation,the reducing components change sharply and have obvious significance of zoning indication.
