Abstract
Abstract
A technique is suggested to separate the effect of conductive overburden from the recorded time‐domain electromagnetic anomalies. Such a separation leads one to construct a relatively undistorted picture of the conductor underlying a conductive overburden. A parameter τ (with dimensions of time) is introduced to characterize various conductors. To illustrate the applicability of the technique, four ‘Input’ (Mark V) anomalies obtained over the Cuddapah District, A.P., India have been analyzed and different values of the time‐parameter τ corresponding to the overburden and the mineralized zones are obtained.
