Approximate Joint Inversion of MT and DC Geoelectric Data in Case of 2D Structures

P053 APPROXIMATE JOINT INVERSION OF MT AND DC GEO-ELECTRIC DATA IN CASE OF 2D STRUCTURES M. DOBRÓKA 1 M. KIS 2 and E. TURAI 1 Summary 1 Using the Generalized Series Expansion method an inversion algorithm is proposed for the processing of DC and MT data measured above 2D structures. In the algorithm approximate forward modeling is applied with the parameters of the locally 1D model. It is shown that GSE inversion gives highly acceptable estimate for the laterally changing parameters of the model. Introduction In the geoelectric exploration of the earth structures magnetotelluric and DC methods are traditionally applied.
