Aeromagnetic characteristic analysis and information enhancement of sandstone-type uranium deposit in the southern margin of Yili basin

  • 为探讨伊犁盆地南缘层间氧化带砂岩型铀矿与航磁数据的内在联系,对盆地南缘蚀源区、地下水径流区、铀矿区和原生带的航磁数据进行了特征分析,总结了一套完整的铀成矿体系对应的航磁特征,认为铀矿通常位于磁场梯度带向宽缓磁场过渡的区间内,ΔT零值可作为由氧化带进入氧化-还原过渡带的标志之一.针对砂岩型铀矿的航磁特征,创新性地将化探领域应用较广的衬值滤波法移植到了航磁数据处理中,铀矿区的空间信息得到了大幅度增强,显示出良好的应用效果.
