Abstract: Through high-precision ground magnetic survey,high-precision aviation magnetic data application,and susceptibility measurements of drill core in Ili basin,the authors made a systematic study which included ferromagnetic mineral distribution characteristics,susceptibility variation characteristics of geochemical zoning of interlayer oxidation zone sandstone uranium deposits and the relationship with uranium mineralization,investigated feasibility,mechanism and methods of locating oxidation-reduction zone lby means of high-precision magnetic survey.The results obtained by the authors have an important role in prediction of front line of the oxidation zone and prognosis of uranium mineralization target. -
