Application study of methods and techniques for weak information extraction of sandstone-hosted uranium deposits

  • 摘要: 砂岩型铀矿弱信息提取及综合评价技术是当前铀矿勘查中重要的研究内容之一。分析了航磁、航放弱信息的形成理论,通过试验建立了有效的弱信息提取模型。在鄂尔多斯盆地东北部开展了砂岩型铀矿预测评价应用,取得了较好的效果。研究结果表明,弱信息提取和综合评价技术可快速缩小砂岩型铀矿找矿靶区,提高预测精度。
    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.
