Abstract This paper describes the theory, equipment and applications of airborne natural electromagnetic system (ZTEM) and comparatively summarizes the measuring parameters, exploration results and working efficiency of both airborne natural EM and ground MT methods. The local-regional exploration scheme of combining airborne EM and ground MT method is proposed based on the above discussion. The ZTEM system is used for rapid survey in large area, thus ground MT is used to follow up the interested points in accessible area and provide a reference for data inversion of a ZTEM survey so as to ensure that the final exploration results truly represent the geological bodies in the whole area. It can provide advanced technologies for rapid and effective exploration in high mountainous, forest-cover, water-cover and environmental protection areas in China.
