METHODS OF MAGNETOTELLURIC ANALYSIS
Abstract
Magnetotelluric prospecting is a method of geophysical exploration that makes use of the fluctuations in the natural electric and magnetic fields that surround the earth. These fields can be measured at the surface of the earth and they are related to each other by a surface impedance that is a function of the conductivity structure of the earth's substrata. This report describes some new methods for analyzing and interpreting magnetotelluric data. A discussion is given of the forms of the surface impedance for various classes of models, including one, two and three dimensional models. Here, an n dimensional model is one in which the parameters describing the model are functions of at most n space coordinates. Methods are discussed for estimating the strike direction for data that is at least approximately two dimensional.
