On the basis of the 1:250000 geological survey in Along Mountain area characterized by shallow forest-covered fields, the authors describe in this paper the technological equipment of the Common Offset Seismic (COF) and electromagnetic dipole methods, and make a comparison between the two methods. Taking into account the geological section drawn by the geochemical method and the longitudinal velocities and resistivities of different rock samples, this paper also discusses the validity and application of the two methods in the shallow fields.
