The study area is located in the south margin of the North China Block, the south end of the juncture between the Ordos Block and the Hehuai Block, which is part of Fen-Wei Graben System and located in the south of Shanxi Cenozoic fault basin in the central part of the North China Craton. The study area has complex regional geological structure, intense tectonic movement and frequent magmatic activities. Based on the latest high-precision aeromagnetic data, integrated interpretation was completed, combining with the existing geological and geophysical research results. According to the block features in different zones of the RTP aeromagnetic data, this article thoroughly studied the characteristics of aeromagnetic anomalies and found the relationship between aeromagnetic anomalies and surface geological information, and the fault distribution, magmatic rock distribution and magnetic characteristics in this area are discussed.
