PSP_006588_1615_RED_abrowse-PCF-LXTT.jpgRelatively young "Rampart" Crater (Absolute Natural Colors; credits for the additional process. and color.: Dr Paolo C. Fienga - Lunexit Team)91 visiteThis image captures the Western Side of a relatively young Rampart Crater located in the Tharsis Region.
Rampart Craters are surrounded by a fluidized Ejecta Blanket (an Ejecta Blanket is the material thrown out around a Crater when the impact occured, in this case resembling the whites of a fried egg, where the crater is the yolk). Researchers speculate that these may form when an object impacts ground that contains fluid (liquid or frozen) that is released upon impact.
THEMIS images V06896002 and V10266002 provide context images for this side of the Crater and show better its Rampart.
Within the Crater we see evidence of Landslides originating at the upper edges. These Landslides have exposed individual Rocky Layers as well as Outcrops of stronger rock types which are more resistant to erosion.MareKromium
