Abstract
After, a methodical overview of the magnetotelluric and telluric methods, the paper with the help of test example from the Pannonian basin (Hungary) illustrates the effectiveness of a combined telluric and magnetotelluric methods in the study of basement structures of deep basins. It is strongly emphasized that in the case of such adeep basin me relation between the gravity map and basin structure may be totally distorted by the crustal-mantle anomalies, first of all by the intrusion of mantle material of high density. Recognising the merits of combined telluric-magnetotelluric method in the exploration of sedimentary basins for hydrocarbon traps, the significance of the application of these methods to Indian sedimentary basins is highlighted. Usefulness of electrical conductance map, derived from these investigations, in demarcating thermally favourable zones of hydrocarbon maturation is envisaged.
