Abstract

Besides the traditional electromagnetic data processing, nowadays one can see more and more transformation solutions (especially for very large data systems), which provide images about deep geological structures and their dimensions free of the orientation of the measuring system. The key parameters of these transformations are called tensor invariants. In this paper the detailed information about the quality, joint interpretation possibilities and applicability of the most used tensor invariants in electromagnetic investigation is presented. Comparison of various invariant results (together with dimensionality analysis) with results of classical magnetotelluric interpretations (inversions) to a 2D datasets in a research area in West-Transdanubia (Hungary) was applied and the main tectonic lines could be identified. In the contact zone of three tectonic units (Pannonian Basin, Eastern Alps and Dinarides), in a complicated – basin and range – geological situation magnetotelluric deep soundings were carried out along a 140 km long profile with a site distance of 2 km. The MT sites followed the Hungarian part of the CELEBRATION-07 (CEL-7) deep refraction profile, and the MT spacing was the same as the seismic one.
