Zusammenfassung:This invention is related to the methods of electro-geological survey. Essentially, it consists in measuring of the process of transient over a polarizable medium using a dipole-axial device as impulses of current are sent through this medium. Several functions are formed in such a way as to ensure different manner of their dependence on the electromagnetic induction field and induced polarization field. One of these functions is formed in such a way as to increase an electromagnetic induction and induced polarization ratio as compared to DU(t)= –¡U(t)/–¡U 0 , where –¡U 0 is the difference of potential ”U measured during the passage of current. The second of these functions is formed in such a way as to decrease the electromagnetic induction and induced polarization ratio as compared to DU(t). The third of these functions is formed as a combination of time and spatial derivatives of the transient field. Simultaneous inversion of all the input functions is executed, including DU(t) obtained in one point of rec
