Abstract

Presents results of magnetotelluric investigations of 19 long-period magnetotelluric soundings along the NW-SE oriented Pannonian Geotraverse. After a brief description of the data acquisition systems and data processing methods used, the measured and interpreted data, giving information about both the deep structure of the lithosphere/asthenosphere and the basinal structure of the region, are presented. The average asthenospheric depth was found to be in the range of 50-70 km, depending on the type of curve and number of sites taken into consideration. Below narrow, deep extensional 3-D subbasins, like the Bekes graben, conducting asthenospheric plumes come up to a depth of about 40 km in accordance with the upwelling of the highly dense mantle material. The stable magnetotelluric anisotropy is due to structural inhomogeneities.
