Abstract: 1294484 Electromagnetic prospecting SCINTREX Ltd 31 Dec 1969 [19 June 1969] 63604/69 Heading G1N The presence of subsurface conductors is determined by energizing an area with a primary field from a fixed source and continuously measuring the relative gradient of a characteristic of the resulting magnetic field with changing location at a substantial distance from the source. As shown, the primary field is produced by a lowfrequency energized coil 30, e.g. several miles in diameter, and the relative gradient of a characteristic, e.g. amplitude, phase, of any component of the resulting magnetic field is detected by a pair of similarly orientated, rigidly spaced coils 10, 12 connected to a bridge 20 and recorder 22. The signal-to-noise ratio may be improved using phase-locking techniques, e.g. a local oscillator which locks on the signal from one of the coils or the transmitter 36 and receiver 38 shown. The primary field may alternatively be produced by V.L.F. radio stations or the earth's lime-varying magnetic field, i.e. due to lightening discharges. Further more than one gradient direction and more than one characteristic may be determined. At a substantial distance from the source, in the absence of a subsurface conductor, the primary field produces a negligible gradient at the coils, but in the presence of conductor, the resulting field generated by that conductor produces a significant gradient.
