huangho deposit (huang-ho'). A general term applied by Grabau (1936, p.253) to a coastal-plain deposit that consists of alluvium that is spread out over a level surface (as a floodplain or a delta) above the normal reach of the sea but that passes laterally into marine beds of equivalent age. Type locality: the loess-derived alluvial deposits at the mouth of the Huang Ho (Yellow River) in northern China. See also: shantung.
