Abstract

Mahanadi Deep Water Basin is located in the Bay of Bengal, south of Bengal shelf, ranging in depth from 100 m to 2.5 Km, covering an area of 80000 Km2. The Basin has accommodated more than 8 km of Upper Cretaceous to Recent sediments. The basin has been formed due to Cretaceous rifting of Gondwanaland and separation of Australia-Antarctica Plate from Indian Plate. The 850E ridge, which divides the basin, is a gravity low anomaly feature.
