Processing of magnetotelluric dates with damped least squares method

Processing of Magnetotelluric Datas with Damped Least Squares Method. Magnetotelluric (MT) Method which is based upon the ideas of Cagniard (1953) is the way of determining the electrical conductivity distribution of the subsur face from measurement of natural transient electric and magnetic fields on the sub surface. Iterative inversion technique is used for the interpretation of MT sounding curves. Damped Least Squares Method (DLSM) for inversion shows a good ap proach. In this research, have been inversion of resistivities and phases of five MT sounding on a profile obtained from a survey in Italy carried out for this purpose. Hence, a computer program that calculates inversion of MT datas was used. Four different models were tried for each MT sounding, and it has showed that obtained apparent resistivities and phases curves with observed values there has been a good coherence.
