The Saurashtra Pen.n.ula an. its adjoin.n. region. covered by Deccan.Traps (DT) are on. of the importan. parts of the In.ian.con.in.n.al lithosphere w.th in.erestin. geophysical an.malies, tecton.-thermal evolution.sin.e the Mesozoic times. Kn.w.edge on.the deep structure ben.ath these formation. is importan. for un.erstan.in. the seismo-tecton.cs of the region. This region.has gain.d importan.e after the occurren.e of a major earthquake (7.9 Mw. n.rth of Saurashtra, n.mely Bhuj earthquake durin. 2001. It is also observed that Saurashtra region.has experien.ed several earthquake sw.rms limited to small region.. Accordin.ly, it is importan. to in.estigate the deep structure of the Saurashtra region.from seismotecton.cs poin. of view. In.our study, magn.totelluric results of the deep crustal structure alon. five n. orien.ed traverses are presen.ed. The five traverses are—Halvad-Rohisa (HR), Sapar-Isw.ria (SI), Mota Dahin.ara-Bamagadh (mb), Jodiya-Jamkhan.orn. (JJ) an. VavBeraja-Devda (VD). The total len.th of these 5 traverses is about 670 km. The derived deep geoelectric structure is also compared an. correlated w.th gravity data to get more con.iden.e on.the derived results. The 2-D geoelectric section.has delin.ated an.malous high con.uctivity structure at places exten.in. from 20 km to about 40 km. From the spatial correlation. an.malous high con.uctive structure derived from MT data w.th in.en.e localized seismic activity is an.in.erestin. observation. In.the presen. study, the results of magn.totelluric studies alon. w.th other geophysical results are presen.ed.
