Using the magnetovariational sounding method to image the deep resistivity structure of the Trans-European suture zone

The conductivity distribution across the Trans-European Suture Zone (TESZ) is presentedbased on the measurements along a 400 km northeastern directed profile, starting fromthe German-Polish Basin, crossing the TESZ and ending at the East European Craton.Two-dimensional inversion was applied to magnetotelluric transfer functions andmagnetovariational responses corresponding to 38 long-period simultaneously observedsites. Input data for the inversion procedure were created by rotating all transfer functionsto strike direction obtained from strike and dimensionality analysis. The results show athick sedimentary cover, several crustal inhomogeneities and a deep conductive structurebelow the center of the TESZ . In order to achieve a stable model, several sensitivityanalysis were carried out
