| Description |
The present study mainly focuses on the northern part of the Cauvery offshore basin, between latitudes 10 degrees and 14 degrees N, and longitudes 80 degrees and 82 degrees E, over which the bathymetry, gravity and magnetic data are collected. The bathymetry map in general shows a linear N-S trend, except between latitudes 10 degrees 45 minutes N and 12 degrees 15 minutes N, where the contours trend coastward indicating a major fault zone. Similar trend is also evidenced by the geophysical anomalies. The free-air gravity anomaly map is characterized by a significant north-south trending linear gravity low with major discontinuities along 12 degrees 15 minutes N and 11 degrees 45 minutes N respectively, indicating major fault zones. Total field magnetic anomaly map also shows two major discontinuities, FG1 and FG2, along 12 degrees 15 minutes N (off Pondicherry), and 10 degrees 45 minutes N (south of Karaikal) respectively
