Extends eastward to the convergent plate tectonic boundaries. At the Chile Triple Junction, near the west coast of the TaitaoTres Montes Peninsula, an oceanic ridge known as the Chile Rise is actively subducting under the South American Plate. The term sial refers to the composition of the upper layer of the Earths crust, It is sometimes thought to be a continental crust, despite the fact that it is absent from the vast oceanic basins, but it is a geochemical term rather than a plate tectonic one. The Chile Rise, located on the southern side, is a divergent boundary between the Antarctic Plate and the Patagonian Plate, allowing magma to escape. Where the two plates meet, the denser oceanic lithosphere of the Nazca Plate is forced down and under the more buoyant continental lithosphere of the South American Plate, descending at an angle into the mantle in a process called subduction.
