Oxia Planum

Oxia Planum
Location Oxia Palus quadrangle

Oxia Planum is a plain located on Mars (near )[1] that has been chosen as a preferred landing location for the ExoMars rover.[2][3]

Oxia Planum contains one of the largest exposures of clay-bearing rocks and are around 3.9 billion years old.[4] The site is iron-magnesium rich clays, indicating that water once played a role here. The site sits in an area of valley systems with the exposed rocks exhibiting different compositions, indicating a variety of deposition and wetting environments.

Clay accumulation underneath the remnants of a fan or delta near the outlet of Coogoon Vallis may offer preservation for biosignatures against the planet's harsh radiation and oxidation environment.[4][5][6]
