摘要
利用HDY-402型三频补偿式航电系统,在内蒙古自治区二连浩特～东乌旗地区获得的实测数据,通过反演计算,将实测的航空电磁场数据转换成反映地下地质体的视电阻率(ρs),根据ρs值的差异及分布趋势,以1:200000地质图为先验条件,对内蒙古自治区二连浩特～东乌旗地区进行了岩性构造填图,显示了该技术良好的应用效果。
This paper presents the results from the flying measured data of HDY-402 three-frequeney airbone electromagnetics system in erlianhot-dongwuqi area of Inner Mongolia Autonomous Region,and the authors carry out the inversion and convert the electromagnetic field into the apparent resistivity(ρs) caused by underground geological bodies.According the differences and distribution trends of the ρs value,lithological and structure mapping was carried out in erlianhot-dongwuqi region of Inner Mongolia compared with the existed 1:200000 Geological map,which shows a good results of the application of the technology.
