Electromagnetic Induction Profile (PREPAN95) from the East European Platform (EEP) to the Pannonian Basin

Complex electromagnetic measurements along a profile crossing different great tectonic units in East-Central Europe (East European Platform, Paleozoic Europe and Carpatho-Pannonian region) were carried out by Hungarian, Polish, Slovak and Ukrainian institutes. Beside recent MT sounding curves, geomagnetic induction vectors, polar diagrams, apparent resistivity and phase pseudosections, a short description of earlier magnetotelluric (MT) and magnetovariational (MV) experiments is also given. For interpretation of these data 1D and 2D inversions were used after separation of the quasi E and B polarized curves. The Carpathian conductor clearly appears in the magnetovariational profile. MT soundings indicate that the mantle conductive basement — presumabely the asthenosphere — steeply deepens from the Neogene Pannonian Basin characterized by high heat flow towards the much colder EEP through the Paleozoic area.
