It lies in the Oxia Palus quadrangle in a region called Margaritifer Terra, and its exact coordinates on Mars are 2°36′N 21°30′W / 2.6°N 21.5°W / 2.6; -21.5.

The floor of Aram Chaos also contains huge blocks of collapsed, or chaotic, terrain that formed when water or ice was catastrophically removed.

This crater was then filled with sediments, likely carried by aeolian processes, that were deposited into Aram Chaos over time.

Subsequently, and in tandem with the compilation of these sedimentary layers, and aquifer formed beneath the surface of the crater.

[7] High resolution MOC images of the chaotic terrains in Aram Chaos show possible volcanic features within the crater, including hills resembling volcanoes, possible magmatic intrusions within the older rock layers, and possible volcanic ash deposits on the crater floor.
