<p>Possible Clays and Olivine in the Wall of Farah Vallis – A thin layer of olivine was detected by the CRISM instrument on MRO, and underlying that, we’ve detected clays. HiRISE can aid in the mapping of these mineralogical signature and give us a better idea for the stratigraphy and thickness of these units.
