Abstract
Based on the field depth magnetotelluric measurements performed in the Tien Shan region, examples of the extraction of an electromagnetic field of endogenous origin are considered. The research was based on the following working hypothesis: irreversible rock deformations (cracking (and)) caused by the development of modern geodynamic processes form sources of the electromagnetic field of endogenous origin. The authors have introduced an approach that suggests the electromagnetic field of endogenous origin to be included in the impedance relations in an additive manner, which allows us to separate the electromagnetic field recorded on the surface, according to the position of the sources. The main point of this algorithm is that the known impedance of the lower half-space requires finding the difference between the tangential components of the electromagnetic field registered on the day surface. To implement the algorithm, a data processing programme for magnetotelluric sensing was compiled in order to identify sources of electromagnetic fields of endogenous origin.
