Interpretation of data of magnetotelluric soundings of inhomogeneous media
Abstract
The present work examines the interpretation of three-dimensional magnetotelluric anomalies on the basis of numerical modeling which makes it possible to carry out calculations for arbitrary relationships of the medium parameters (resistance and conductivity). Emphasis is placed on three problems: (1) the investigation of the effect of three-dimensional inhomogeneities of the sedimentary mantle on the magnetotelluric field; (2) the development of difference methods for the solution of two- and three-dimensional magnetotelluric problems; and (3) the choice of gradient models as the background geoelectric section. Results are presented for the Far East, the Caucasus, and Central Asia.
