The archaeological excavation can be usefully addressed by the results of surface geophysical investigations. Th ese investigations are based on the diff erentiation of some physical properties of the archaeological material and host soil. Th e most commonly used are the magnetic susceptibility, electrical resistivity and dielectric permittivity. Th e fi rst is related to the presence of magnetized mineral fragments, the second to the diff erent attitude of terrains and archaeological materials to conduction of the electric current, the third to the speed of propagation of electromagnetic waves, which are refl ected at the surfaces of discontinuity. Some examples illustrate how the various investigations are carried out and the eff ectiveness of their results.
