Remote reference (RR) magnetotelluric (MT) measurements were carried out over Eastern Indian craton. All the data processed with hybrid robust technique. A stitched section was prepared from 1-D MT inversion scheme using very fast simulated annealing (VFSA) technique which served as an input for 2-D modelling. VFSA splines bas been used inversion. subsurface conductivity model craton shows that granitic crust is electrically homogenous high a resistivity 30,000 ohm-m. Its depth extent 38 km.
