Magnetic anomalies in Central Bengal fan

Abstract

Total magnetic field anomalies recorded over the Central Bengal Fan are analysed and the depths to the magnetic basement are computed using the analytical signal and the Werner deconvolution methods. To the west and east of 85 degrees E, the basement layer delineates the basement high and the Graben, both trending nearly parallel to the east coast of India. The basement high recorded from the present studies nearly coincides with the 85 degrees E ridge and the western flank of the Graben reported earlier in this region
