Description:
Deep magnetovariational soundings have been carried out using the data of the geomagnetic observatory net and the MAGSAT satellite. Complex apparent resistivities estimated from satellite data by two independent methods are found to be in accordance with numerous mean values obtained only from ground data. Assuming the spherical symmetry of the Earth's layers the interpretation in the parametric models class of joint results has been done. The global estimation of the electrical conductivity structure of the Earth's mantle indicates the presence of a high conductivity layer about 200 km thick at a depth of approximately 600-700 km. © 1993, Society of Geomagnetism and Earth, Planetary and Space Sciences.
