Abstract

Gravity and magnetic studies have been carried out along Rewa to south of Shahdol transect, Madhya Pradesh, Central India to understand the nature of the structural features conjugated with different geological entities and thickness sedimentary column. The detail gravity and magnetic data have been collected along 220 km long profile with 0.5 km station interval. The qualitative analysis of the data shows multiple geological entities i.e Mahakoshal, Gondwana sediments and deccan trap including deep seated faults (F1: SNNF, F2: SNSF and F3). Further, signature of sediment column under the deccan trap is also identified. Spectral analysis of the potential field data reveals the average depth of the deeper crustal layer approximately 21 km and depth to the basement (Mahakoshal/Crysatalline) 4.0 km on which Gondwana sediments were deposited. The thickness of the vindhyan sediments at Rewa and south of shahdol are estimated as 2.2 km and 450 m respectively. The results are well correlated with the deep borehole data and with gravity and magnetic results, Magnetotelluric and Deep seismic studies. Theese finding may be useful to develop a conceptual model for exploring mineral and energy resources along Rewa to Shahdol transect
