      • Abstract
    • Weak information extraction and integrated evaluation of sandstone-hosted uranium deposits is currently one of the important research subjects in the uranium exploration. In this paper, the authors described the formation theories of aeromagnetic and aero-radioactive weak information and established effective mathematic models for weak information extraction. The integrated evaluation of metallogenic probability about sandstone-hosted uranium deposits was completed and the better effect was obtained in the northeast Ordos Basin. The research results prove that techniques of weak information extraction and integrated evaluation can further delineate the prospective areas of sandstone-hosted uranium deposits rapidly and improve the predictive precision.
