Salty Environments: The importance of evaporites and brine environments as habitats and preservers of biosignatures

The habitability of ancient Mars is directly related to the presence of late Noachian surface waters and their stability over geologic time. Evaporite minerals can capture and entomb organic matter, biological compounds, and intact cells within their intercrystalline and intracrystalline structure because they precipitate relatively quickly.
