摘要
磁性地质界面的反演是地球物理勘探的重要课题之一,对于提高磁测资料的地质解释效果有重要意义.通过磁测资料反演磁性地质界面主要分两步:第一步,从总异常中分离有磁性界面起伏引起的磁异常;第二步,由分离的磁异常反演磁性界面的深度.本文分别从这两个方面回顾了提取异常和反演界面的较有代表性的技术.
The inversion of magnetic geologic interface is an important task in geophysical prospecting, it has an important implication of improving the effect of geological interpretation of magnetic measurements. There are two steps to inverse a magnetic geologic interface using magnetic data： the first, magnetic anomaly that results from magnetic interface undulation is separated out from total anomaly; the second, inversion of the separated anomaly to obtain the depth of the magnetic geologic interface. This paper reviews the main technology from the two aspects.
