Description Magnetic data over the eastern continental margin of India and adjacent Bengal fan demarcate two major lineaments. A high amplitude N - S trending lineation of the Cauvery offshore Basin corresponds to the offshore fragment of the 80 degrees Elineament recorded onland. A N - S lineation of very high amplitude anomaly off Chilka lake considered as the possible northward extension of the 85 degrees E ridge delineated, hitherto in Bengal Fan. A subduced magnetic anomaly zone is demarcated seaward of the continent-ocean boundary (COB) in the Bengal Fan. Over the northern Bengal Fan this zone is delineated east of 85 degrees E lineation. This quiet zone might have evolved during the Early Cretaceous period of normal magnetic polarity between MO and 34 (120 - 84 Ma) anomalies
