APPLYING THE HORIZONTAL SPATIAL GRADIENT METHOD FOR THE DEEP CONDUCTIVITY ESTIMATIONS IN THE UKRAINE

摘要

The analysis of the long-period magnetovariation data obtained in the Ukraine and from the project PREPAN-95 are presented. The response functions have been estimated for the harmonics of daily variations for the periods of 4-24 hours using the horizontal spatial gradient method of the magnetic field components. These results together with data of the nearest geomagnetic observatories have given the possibility to compare the mantle geoelectrical structures for three different tectonic regions in the Ukraine. The greatest difference is observed between the Ukrainian shield and the Carpathians together with the Tornquist -Teisseyre zone.
