METHOD FOR GEOPHYSICAL PROSPECTING OF COMPLEXOREBODIESABSTRACTA method for geophysical prospecting of complex ore-bodies, wherein elastic waves are excited at least twotimes in the rock mass containing orebodies and the radio--frequency electromagnetic pulses produced by said orebo-dies are recorded during each excitation to pinpoint thearrival time of the first and last pulses in each pulsetrain, then the difference is found between the maximumarrival time of the last pulse and the minimum arrival timeof the first pulse in the pulse trains representing oneorebody, said differences being the basis for determinationof the thickness of each orebody.Accompanying drawing.
