Outlook of IP anomal effect of a body settled in the electric field of an underground point current electrode

The borehole underground IP survey present one of the main directions to increase the depth investigation of Electrical Prospecting for topper ore deposits search. The IP anomal effects are strongly increased when the current source is aproached the underground polarizable are bodies. Moreover, the outlook of spacial distribution and the intensity of this effect are quite different in comparison with cases when current arrays are settled into earth's surface.
