Nazca Plate The lithospheric plate which is subducting under the South American Plate along the line of the Peru—Chile Trench. Its other plate margins are the ridges and transform faults which separate it from the Pacific, Cocos, and Antarctic Plates. The Nazca Plate is thought to have decreased in size: the former, more extensive plate has also been called the Phoenix Plate.
