The Argentine Basin is formed by the eastern continental slope of the South American Plate and by the Falkland Escarpment, the edge of a submarine plateau. At its deepest point located at the base of the escarpment, is the Argentine Abyssal Plain. The Argentine Basin shows the typical featureless quality of abyssal plains, and in this respect is quite different from the Drake Passage and Scotia Sea which exist south of the Falkland Plateau.
