Western Continental Margin of India and Hydrocarbon Potential of Deep-Sea Basins

S. K. Biswas, N. K. Singh


The Western Continental Margin of India is a passive margin, extending NW-SE form Kutch to Comorin. It is tectonically differentiated into a shelfal horst-graben complex and paired ridges and depressions. The horst-graben complex of the shallow- water shelf is bordered by the pair of narrow Kori-Comorin depression and ridge all along the the margin. These elements cut across the shelf-slope boundary. The Kori-Comorin ridge is followed, in the deep basinal part, by the pair of Laxmi- Laccadive depression and ridge.

Two main phases of evolution of western margin of India - early rift phase and post-rift phase, have been identified. The depositional models of these two phases indicate that the deep- sea basins of western margin of India are prospective. The prospects encourage to exploration ventures in the deep water beyond 200 m isobath.
