Abstract
An approach has been applied, according to which the electromagnetic field of endogenous origin is included in the impedance relations in an additive way, which allows to separate the electromagnetic field recorded on the day surface in compliance with the position of sources. Practical examples of distinguishing an electromagnetic field of endogenous origin in field recordings of magnetotelluric soundings performed in the Tien Shan region are presented. The characteristics of the distinguished electromagnetic field of endogenous origin are compared with the parameters of lunar-solar tides and anisotropic properties of electrical resistance The detected relationships of these parameters indicate new possibilities for studying permanent deformations in the Tien Shan lithosphere using magnetotelluric data.
