摘　　要：在对研究区航放航磁数据进行整理并编图的基础上,归纳总结了研究区航放、航磁特征。对区内典型铀矿床航放航磁特征进行分析研究,利用航放K、U、Th以及航磁ΔT化极数据求取各转换参量共36种,使用俄罗斯半定量成矿预测软件判别分析结果选取19种参量建立了塔木素铀矿床数学-物理找矿模型,并将模型应用到研究区开展找矿远景预测,圈定了塔木素—乌力吉、银根—本巴图、雅布赖等三片成矿有利区。认为该三片有利区具有较好的找矿潜力,为开展下一步工作提供了线索。On the basis of collection and mapping of the airborne radioactivity and aeromagnetic data of the study area,the paper has summarized airborne radioactivity and aeromagnetic characteristics of the study area.For the analysis of airborne radioactivity and aeromagnetic characteristics of Tamusu uranium deposit,36 kinds of conversion parameters are obtained by using areo-radioactive K,U,Th and aeromagneticΔT polarizing data.The mathematical and physical prospecting model of Tamu uranium deposit is established to select 19 kinds of parameters based on the discriminant analysis result of Russian semi-quantitative metallogenic prediction software.The model is applied to to carry out prospecting prospect prediction in the study area,and three favorable ore-forming areas such as Tamusu-Wuliji,Yingen-Benbatu and Yabulai are delineated.It is concluded that the three favorable areas have a good prospecting potential,which provides the exploration clues for the further work.
