    Abstract
    Total magnetic intensity data were collected over the Direction Bank, off Bombay on the western continental shelf of India and the isomagnetic anomaly map prepared at a contour interval of 25nT show NNW-SSE trend resemble those of the Dharwarians. Two dimensional model studies were carried out to understand the basement configuration of the Direction Bank. Derived models indicated that the source of the anomalies lie at a depth of 2.2 to 3.0 km and suggest that the subsurface formations were faulted over the Bank. A comparative study of these models with the seismic sections of ONGC suggest that the sources of the anomalies are from the Middle Eocene base present at those depths and indicate faulting of the Eocene base over which the present configuration of the Direction Bank lies
