A volcanic environment for bedrock diagenesis at meridiani planum on Mars

Article Abstract:

An alternative model is proposed for diagenesis of Meridiani bedrock that involves deposition of volcanic ash followed by reaction with condensed sulphur dioxide and water baring vapours emitted from fumaroles. The model proposed for the Meridiani bedrocks has implications for the history of water and potential habitability of Mars that are significantly different from the sedimentary deposit/evaporite model proposed by the MER team.

Implications for hydrologic processes on Mars from extensive bedrock outcrops throughout Terra Meridiani

Article Abstract:

A remote sensing data is used to show that the light-toned outcrops at the landing site are not a local phenomenon. The Mars Emission Exploration Rover Opportunity landed in Meridiani early in 2004 and has since discovered light-toned bedrock outcrops rich in chemical and textural signatures of long-term water interaction locally at the landing site.

Meridiani Planum and the global hydrology of Mars

Article Abstract:

Presence of evaporitic sulphate mineral in Meridiani Planum region of Mars suggests possibility of ancient groundwater networks. Presence of evaporites is investigated.
