The offshore Indus basin is a rift and passive margin basin which developed following the separation of the Indian Plate from Africa in the late Jurassic. During the Late Cretaceous, the separation of Madagascar from India occurred and was followed by rapid northward movement of the Indian plate. In the early Paleocene, the Indian plate passed over the Reunion hotspot. This event also led to the extrusion of large volcanic rocks, known as the Deccan Traps. During the Eocene, the Indian plate collided with the Eurasian plate, uplifting the Himalayas. Presence of the Middle Eocene sandstones in the distal Indus fan, which contain feldspar grains with an origin in or north of the Indus suture zone, is an evidence to the occurrence of this event. The Indian plate continues to collide with the Eurasian plate as shown by earthquakes in and around the Himalayas.
