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.Keywords

A 560 m thick rock succession of Middle Bhuban Formation (Surma Group) exposed between Bawngkawn and Durtlang, Aizawl, Mizoram has been studied for its magnetostratigraphic attributes. A total of 7 normal and 7 reverse magneto-Zones have been delineated in this section. The GPTS correlated ages of this section lie between -21.77 Ma (at the base) to ∼15.16 Ma (at the top) with a total duration of ∼6.6 Ma. The GPTS event C6n occurring at the stratigraphic level between 146 m to 266 m may be considered for basin wide correlation as it is the longest normal event that has been recorded with greater confidence i. e. better alpha- 95. The average sediment accumulation rate (SAR) estimated for this section is 8.48 cm/Ka. Overall the SAR is higher in the lower part of the section with a spike of 26.8 cm/Ka at <21 Ma. The decrease in SAR to 2.1 cm/Ka at around 18 Ma in the upper part of the section may be investigated for possible hiatus.Keywords
