In this study, we obtained information on the characteristics of the lithosphere magnetic field in the study area using four mobile geomagnetic observation datasets recorded in the Fujian region during 2014-2015. In order to separate shallow and deep anomalies, the data was processed with upward continuation, at depths of 5 km, 10 km, 20 km, and 30 km, among others, and the deep anomalies were extracted. The results show that there were obvious geomagnetic anomalies in the Changle-Zhaoan fault zone, which might be related to the geological structure distribution and the seismic activity in the Fujian region.
