To expand the scope of unsteady electromagnetic fields in marine and land prospecting and mapping studies of deep-seated and/or polarized geological objects, such as oil and gas deposits, kimberlite bodies and other minerals, it is advisable to consider an engineering-analytical multicomponent model of an electrically conductive layer when excited by horizontal electric dipole – the classic causative agent of the formation of the field of horizontally layered media. To simplify analytical studies, the Cole-Cole dispersion model adopted for the polarized known plane S η was adopted as polarizable electrically conductive layer. The components of analytical expressions are described that describe the establishment of the electromagnetic field of an induction-induced polarizing conductive layer — objects of hydrocarbon deposits and sulphide ore occurrences. To identify the deep horizontal inhomogeneities of the section, equations are given that describe multicomponent fluxes of magnetic induction of polarized formation.
