Description Inversion of magnetic data was carried out on 40 profiles collected across the continental margin of Visakhapatnam, Andhra Pradesh, India at a spacing of about 10 km and magnetic basement map for this region is prepared. The map reveals complex anomalies particularly beneath the inner shelf with amplitudes reaching as high as 1880 nT. These anomalies appear to be associated with the complex basement structure reported earlier. The significant features inferred include, (1) a shallow and highly faulted basement, in the inner shelf; (2) a NE-SW ridge-trough configuration in the mid shelf; (3) NW-SE trending basement upward off Bhimunipatnam to Kalingapatnam and (4) N-S trending shallow basement trend off Chilka Lake.
