Abstract
During recent years many magnetotelluric (MT) and magnetovariational (EM) soundings across the Northeast German and the Polish Basin have been realized. Two-dimensional (2-D) models were constructed for most of the obtained data of the study area. However, there are clear indications for three-dimensionality, particularly seen in the behaviour of induction vectors. Therefore 2-D modelling can only be regarded as a first step in interpretation that might even yield a false image of conductivity structures at depth. The primary objective of this work was to obtain a detailed, three-dimensional image of electrical conductivity distribution in the Earth’s crust below the Trans-European Suture Zone (TESZ) in the northwest part of Poland (Pomerania). To achieve this purpose we applied a 3-D inversion code (Siripunvaraporn et al. 2005), which allowed us to obtain more realistic model geometries. We got a clearer image of the highly conductive rock complexes, which we tentatively connected to deformation fronts, as well as their position in relation to the margin of the East European Platform (Dadlez, 2000).
