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(ρ_s) caused by underground geological bodies. According the differences and distribution trends of the ρ_s 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.
