The nature of horizontal anomalies and magnetotelluric impedance over southern India
The nature of horizontal anomalies and anomalous current systems in the region of the southern Indian peninsula is theoretically calculated with the aid of a thin sheet algorithm for northward and westward polarizations of a uniform inducing magnetic Held of period 20 min. The numerical model of the geoelectric structure is the one devised by Agarwal and Weaver (1989). The model results indicate the correspondence between the general features of the computed horizontal anomalies and the observed anomalies both at temporary array stations and at two permanent magnetic observatories (ANN and TRD). On the basis of model estimates of apparent resistivity and phase it is suggested that a one-dimensional interpretation of the sub-surface conductivity structure is valid near two of the array stations, whereas at all other coastal and inland stations, two-or three-dimensional interpretations of magnetotelluric (MT) data are required.
