The western sector of the Greater Antilles Outer Ridge was probably built out over flat-lying sediments in middle to late Miocene time. Deposition of the Caicos Outer Ri dge began shortly thereafte~ and increased deposition occurred on the western Greater Antilles Outer Ridge, a condition which has persisted to the present.
