PCT No. PCT/SU84/00048 Sec. 371 Date Apr. 11, 1986 Sec. 102(e) Date Apr. 11, 1986 PCT Filed Aug. 21, 1984 PCT Pub. No. WO86/01609 PCT Pub. Date Mar. 13, 1986.A method for geophysical prospecting of complex orebodies, wherein elastic waves are excited at least two times in the rock mass containing orebodies and the radio-frequency electromagnetic pulses produced by said orebodies are recorded during each excitation to pinpoint the arrival time of the first and last pulses in each pulse train (1,2,3,4,5,6), then the difference is found between the maximum arrival time of the last pulse and the minimum arrival time of the first pulse in the pulse trains (1,3,5 and 2,4,6) representing one orebody, said differences being the basis for determination of the thickness of each orebody. |
