GEOPHYSICAL INVESTIGATIONS BY TRANSIENT ELECTROMAGNETIC (TEM) METHOD
The transient electromagnetic (TEM) method of mineral prospecting has been investigated. Empirical field studies have been made in controlled mineral environments using two commercial TEM systems. The test surveys have demonstrated the operational and coupling characteristics of the coincident, vertical and separated loop geometries, and the type of TEM response to be expected for a variety of target situations. A parametric model study of the TEM coincident loop technique has been undertaken to provide a generalised scheme for the interpretation of TEM anomalies, and to provide insight on the important survey design parameters. Substantial agreement has been found between theoretical responses based on simulated targets, and field responses obtained over known mineral deposits. The study indicates that TEM techniques in general offer inherent advantages over traditional frequency domain systems, particularly for deep mineral exploration.
