Figure 5(a): The archetype of chaos areas that have been mapped as green in Fig. 3. This area is within the large "green" unit east of Mannan'an. The archetype for terrain marked as red is Conamara (Fig. 1).
Figure 5(b): A montage of several examples of chaos features that have been marked as blue in Fig. 3. These features are interpreted as the last vestiges of old chaos areas, which have survived because there topography makes them relatively immune to destruction by tectonic resurfacing.
