Title: The ongoing collision of India and Asia, starting about 45 million years ago, produced the majestic Himalayas.
Caption: A. Converging plates generated a subduction zone, while partial melting triggered by the subducting oceanic slab produced a continental volcanic arc. Sediments scraped from the subducting plate were added to the accretionary wedge. B. Position of India in relation to Eurasia at various times. (Modified after Peter Molnar) C. Eventually the two landmasses collided, deforming and elevating the sediments that had been deposited along their continental margins.
