Abstract

Frequency-domain electromagnetic (EM) sounding is becoming an increasingly useful deep-exploration tool with recent applications to crustal sounding and geothermal exploration (Tripp et al, 1978; Sternberg, 1979; Duncan et al, 1980; Stark et al, 1980). A major drawback of the method is that most field data are analyzed by computer after the data are returned to the laboratory; no intermediate parameters, such as apparent resistivity, are calculated to provide on-site information. The following example illustrates this problem.
