摘要
Based on the forward formulae for the fixed-wing electromagnetic system,the IQ method and the amplitude-altitude method are introduced,by the homogeneous half-space model of apparent resistivity conversion.The airborne electromagnetical data in high,middle and low frequency are collected in one area in Inner Mongolia,and are converted into the apparent resistivity,namely Hρs,Mρs,Lρs.After comparing the geological mapping effects among Hρs,Mρs and Lρs,the Hρs contour map is considered as the best one to reflect lithostructural mapping,to improve the practical meaning and application of air apparent resistivity mapping by contrasting with the original geological maps,providing a theoretical basis for the final period data interpretation.
