    Abstract
    Bathymetric and magnetic data along 25 profiles covering the Bombay High and adjacent area on the mid-shelf and inner shelf off the Bombay Coast are studied. Except for the NW-SE and ENE-WSW trending anomaly closures in the east of the high, the magnetic anomalies mostly trend E-W. Correlation of the anomalies with well logs reveals that the positive magnetic anomalies aries from the basalts (December Traps) underlain by granites. Two-dimensional model studies of the anomalies under numerical constraints reveal (1) the structure of the magnetic basement and (2) sediments of 2.0 to 3.5 km thickness resting on the basalts, the latter reaching 0.8 km in thickness. Maps of the surface model of the basalts and granites, the basalt isopachs and the nature of the basement are prepared. The basement structure models with steep slopes in the south and discontinuous zones in the east which are interpreted in terms of pre- to post-basement faults.The faults, which are of regional extent, divide the crustal blocks underlying the mid-shelf from those of the inner shelf. The significance of the present study is discussed in the context of hotspot and plate tectonic concepts relating to Mascarene Plateau and Western India.
