Abstract
Cartoon illustration of structure (Northern part of Saurashtra region) brings out three different basins beneath Deccan traps from magnetotelluric studies. Crustal inhomogeneities are brought out by different resistivity and conductivity zones. R1 and R2 forms the uplifted blocks of Jamnagar basin, R2, R3 forms the uplifted blocks of Jasdan basin and R4 forms the western fringe of Cambay basin. Conductivity anomalies C2 and C3 denote the trapped carbonate fluids expelled from recrystallized resistivity blocks whereas C4 denotes conductive dyke that may be the source for Deccan volcanism. Conductivity anomaly (A) may represents interconnected melts.296
