Definition

Intracrater occurrence of chaotic terrain; a crater interior morphology.

Category

A type of  modified crater

A type of  chaotic terrain (Mars)

Synonyms

Chaotic floor crater (CF); Collapsed crater (CC, Rodriguez et al. 2005).

Description

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.
