Chaotic Terrain (Mars)
Reference work entry
Distinctive area of broken terrain that primarily consists of polygonal, flat-topped blocks of various sizes, of which many preserve remnants of the surrounding upland surface.
Chaos; Chaos region
Chaotic terrains are irregular to circular fractured areas (Figs. 1 and 2) that consist of jumbles of blocks that vary in size and shape from knobs and irregular conical mounds to angular mesas with preserved remnants of the upland plateau, and they are often located in enclosed to semi-closed depressions surrounded by fractured highlands (Sharp 1973; Nummedal and Prior 1981; Warner et al. 2011).
