Transient EM in the eastern goldfields

Abstract

Fig. 1 shows the results of a transient EM traverse MPPO-1 across a pyrite body on the edge of a salt lake in the Eastern Goldfields of Western Australia using 100 feet loops at 50 feet spacings. The results are presented as stacked profiles of the received signal strength at ten delay times ranging from 1.0 to 15 milliseconds after the cutoff of the transmitted pulse. To allow all values to be plotted the vertical scale used is linear to 100 uV and logarithmic beyond 100 uV.
