Deposition of sediments at the mouth of submarine canyons may form enormous fan-shaped accumulations called submarine fans on both the continental slope and continental rise. Alluvial or sedimentary fans are shallow cone-shaped reliefs at the base of the continental slope that merge together, forming the continental rise. Erosional submarine canyons slope downward and lead to alluvial fan valleys with increasing depth. It is in this zone that sediment is deposited, forming th… WebFeb 22, 2016 · The process, called relamination, starts at the edge of a continental plate, where an oceanic plate is diving under the continental plate and magma is rising to form …
