A very unusual triple junction arises due to the fact that this plate is diverging from the Antarctic plate, forming a mid-ocean ridge that is being subducted.
The processes that gave rise to the Laramide orogeny can be studied using this present-day plate because it is unusually undergoing flat-slab, or shallow angle, subduction. A very unusual triple junction arises due to the fact that this plate is diverging from the Antarctic plate, forming a mid-ocean ridge that is being subducted. This plate's northern border with the Cocos plate, with which it is part of a triple junction, includes a mysterious "gore" in which the Galápagos Islands lie. Its subduction is responsible for the Andean orogeny. For 10 points, name this eastern Pacific plate that is being subducted by the South American plate and is named for a region in Peru.
