Abstract

In the area of the typical 3D Békés basin ("graben") high anisotropy (difference) appears in the extreme values of the magnetotelluric impedance phases in the period interval corresponding to the indication of the conductive asthenosphere. As proved by the forward 2D/3D modelling, this anisotropy can only be explained by a strong 2D effect. This fact may confirm the validity of the results of the 2D inversion of PGT1 magnetotelluric data indicating the upwelling of the asthenosphere below the Békés basin.
