Geoelectric parameters of the northwestern part of the Ukrainian Shield from 2D inversion

open access: yesГеофизический журнал, 2020
Based on a 2D inversion of magnetotelluric data along six meridional profiles traversing the northwestern part of the Ukrainian shield, local objects of reduced resistivity (with ρ < 100 Ohm · m) in the Earth's crust and upper mantle are identified.
