Abstract:
The problem of developing a normal model of the electric conductivity of the continental lithosphere is currently at the level of discussion, despite more than half a century of the deep electromagnetic sounding. In the present paper, the normal model is understood as a model of electric conductivity of the lithosphere (shield and platform) free of the lateral influence of the Earth's crustal conductors, marginal seas, and other objects of horizontal electric inhomogeneity. Such a model should reflect a one-dimensional distribution of electric conductivity at a particular depth, as it depends on the composition, thermodynamic state, and fluid regime of the Earth's interior.
