Description Continuous records of the total earth's magnetic field and the surface sediment samples from the ocean bottom have been collected off Ramakrishna Beach and Lawsons Bay along the Visakhapatnam Coast. The magnetic data has recorded significant anomalies upto 15 m water depth. The bulk percentage of the heavy mineral concentration varies between 20 and 40% upto 15 m water depth. In Lawsons Bay area, a large amplitude magnetic anomaly with its peak to peak value of more than 700 nT extending beyond 30 m water depth has also been recorded. Two dimensional modelling of this anomaly has revealed a shallow intrusive body with its upper surface faulted on either side
