A study was made of the magnetotelluric sounding method involving a tensor impedance relationship between the surface electric and magnetic micropulsation fields of the earth. A theoretical treatment of the tensor impedance including the vertical magnetic field relationship is offered with emphasis on its response to three-dimensional geometry. Some approximate mathematical models are proposed for use in interpreting three-dimensionality in the surface impedance. An experimental investigation conducted in central Texas is fully discussed.
