Two end-member scenarios of the India-Eurasia collision were tested. The conventional model invokes long-lived Andean-style subduction along southern Eurasia until continental collision between a maximum extent Greater India and Lhasa at ~60 Ma. The alternative scenario includes Tethyan intra-oceanic subduction, with back-arc opening along southern Eurasia from 120 to 50 Ma, and an initial collision between a smaller Greater India and the intra-oceanic subduction system at ~60 Ma. The back-arc is then subducted along an Andean-style margin until final continental collision at ~40 Ma.
