Abstract:
The magnetovariational data in horizontal and vertical field components recorded along a profile running across the SONATA and Satpura ranges are separated into its external and internal parts with an objective to decipher the configuration of anomalous currents associated with an elongated Satpura conductivity anomaly (SCA). The inferred distribution of anomalous internal currents approximate the SCA as an arcuate structure with its upper surface simulating asymmetric anticlinal geometry, in close agreement with the results of numerical modelling. In retrospective sense the results demonstrate that constraints provided by mapping the configuration of internal current distribution can be used as a guide on the choice of conductive structures to be investigated by modelling.
