摘要: 本文以鹿井地区和相山地区为例,阐述利用音频大地电磁测量勘探方法在南方红盆地区铀矿勘查中的应用,有效得划定了红层厚度以及产状,并且对红盆地区地层的划分以及断层的识别效果较好.通过反演电阻率断面图能够清晰地反映主要含矿层位的厚度、埋深、岩性接触界面的形态等特征,间接地指示铀矿化赋存的部位,是红盆地区铀矿勘查的一种有效方法.Abstract: Based on the applications of audiomagnetotellurics survey in both Lujing and Xiangshan area,the au-thors expound the exploration measurement method of AMT in uranium exploration in the south of the red basin,and effective drew red layer thickness and occurrence,the red basin in stratigraphic division and fault recognition effect is better.Through the inversion of resistivity profile can clearly reflect ranks as one of the main ore-bearing layer thickness,buried depth and lithology of the contact interface morphology characteristics,indirectly indi-cates occurrence of uranium mineralization,which is an effective method of uranium exploration in the red basin area.
