| Zusammenfassung |
| In the Eastern end of the Eastern Alps – at the Austrian-Hungarian border – there are Pennninic Nappes among them the Köszeg-Rechnitz tectonic window having complicated metamorphic history from the Jurassic time. The organic material of the Penninic Ocean transformed to meta-anthracite. Its amount in the calc-phyllite has been estimated by the geochemists to 0.2 percent.
Magnetotelluric soundings have been carried out to determine:
– the resistivity decrease due to the above amount of conductive material,
– the different EM distortions in E and B polarization caused by the conductor near and far from it,
– the asthenospheric depth in the area of the tectonic window stepping out from the shallow asthenosphere of the Pannonian Basin,
– looking for relation between geoelectric and seismic crustal structures. |
