Description Total magnetic field intensity measurements along two parallel NW-SE tracks from the Direction Bank to the Kori Bank show corelatable magnetic anomalies. High frequency positive anomalies observed northwest of Kathiawar coast terminating at about 21~'N are interpreted due to the magnetic basement i.e., basalts at a depth of about 2km. A low amplitude negative anomaly observed around 21~'N (between 69~'E and 70~'E) may be due to the westward extension of the Narmada-Son lineament. Absence of significant anomalies south of these high frequency anomalies may be due to thin Traps or greater thickness of sediments. High amplitude and broad wavelength negative anomaly observed off Bombay (19~'N, 71.5~'E) is interpreted as due to contact or faulting of Precambrian formations and Deccan Traps
