Abstract

A special geologic-tectonic unit (the Carpathians and the surrounding Russian Platform) was selected to demonstrate the efficiency of electromagnetic induction methods from the point of view of geodynamics. In these regions there are significant changes in the distribution of electric conductivity due to difference in geologic structure and in geophysical parameters. After a description of recent geodynamic conceptions concerning the Carpathian system and a short review of the induction methods used in this region, conducting layers (or conductivity increases) detected in the Earth's crust and upper mantle are presented. Finally the role of the conductivity anomalies in developing geodynamic models is emphasized. Typical temperature-depth functions, and the connection between the main tectonic lines and the anomalies are also discussed.
