Chapter 3: Statement of the Magnetotelluric Problem

3.1 THE TIKHONOV-CAGNIARD TRANSFORMATIONS

The unfortunate peculiarity of magnetotellurics lies in the fact that we solve a geoelectric problem in which the source of an electromagnetic field is unknown (more exactly, it is known, but only in a very general way). How can we avoid this difficulty? The fundamental idea for the magnetotelluric method can be formulated as follows. Because we do not have precise information on the distribution of currents in the magnetosphere or the ionosphere, we must abandon a traditional geoelectric concept based on the study of the relationship between electromagnetic fields and their sources, and proceed to determine the electric conductivity of the earth by studying the ratios between the electric and magnetic fields, or between the various components of the magnetic field. This idea of Tikhonov’s opened a new period in the development of the technology of geoelectric methods and electric exploration.
