Chaotic Crater Floor (Mars)
Reference work entry
Intracrater occurrence of chaotic terrain; a crater interior morphology.
Chaotic floor crater (CF); Collapsed crater (CC, Rodriguez et al. 2005).
Knobs and irregular mesas that occur in groups or as isolated features (van Kan Parker et al. 2010) inside martian craters (Figs. 1, 2, 3, and 4). Their extent is limited to (1) the inner margin of the crater rim or (2) a circular moat if no rim is present. Craters exhibiting chaotic floor are typical starting points of small and medium size outflow channels and occur in close proximity of chaotic terrains and fractured floor craters (Korteniemi et al. 2006 and references therein). Some collapsed floor craters have no apparent outlets.
