Abstract
Magnetic and bathymetric data collected in the Central Indian Basin, between 8°S and 16°S latitudes, and 71°E and 82°E longitudes have been studied. The inferred fracture zones at 73°E, 76°30′E and 79°E demarcate the Central Indian Basin into zones, depicting right lateral offsets of the magnetic lineations A21 to A26. Multibeam sonar surveys carried out over a part of the study area depict bathymetric evidence for the 79°E fracture zone. Several seamounts are mapped in this region based on echosounding and multibeam sonar data. It is observed that these seamounts cluster along the fracture zones. The tectonic implications of the seamount distribution in relation to the fracture zones are discussed.
