In the late Cretaceous, approximately million years ago and subsequent to the splitting off from Gondwana of conjoined Madagascar and India, the Indian Plate split from Madagascar. It began moving north, at about per year, and is believed to have begun colliding with Asia as early as million years ago, in the Eocene epoch of the Cenozoic. However, some authors suggest the collision between India and Eurasia occurred much later, around million years ago. If the collision occurred between 55 and 50 Mya, the Indian Plate would have covered a distance of , moving more quickly than any other known plate. In 2012, paleomagnetic data from the Greater Himalaya was used to propose two collisions to reconcile the discrepancy between the amount of crustal shortening in the Himalaya (~) and the amount of convergence between India and Asia (~). These authors propose a continental fragment of northern Gondwana rifted from India, traveled northward, and initiated the soft collision between the Greater Himalaya and Asia at ~50 Mya. This was followed by the hard collision between India and Asia occurred at ~25 Mya. Subduction of the resulting ocean basin that formed between the Greater Himalayan fragment and India explains the apparent discrepancy between the crustal shortening estimates in the Himalaya and paleomagnetic data from India and Asia. However, the proposed ocean basin was not constrained by paleomagnetic data from the key time interval of ~120 Mya to ~60 Mya. New paleomagnetic results of this critical time interval from southern Tibet do not support this Greater Indian Ocean basin hypothesis and the associated dual collision model.
