In situ evidence for serpentinization within the Máaz formation, Jezero crater, Mars Open
As both a source of atmospheric H 2 and a sink for liquid water, the serpentinization of olivine-bearing rocks is widely thought to have influenced the long-term evolution of the early martian atmosphere and hydrosphere. However, the mecha…
