Investigation of Sodium Sulfate Spectra from the Great Salt Lake as a Model for Characterizing Aqueous Geochemistry and Climate History of Martian Paleolakes
[#2143]
We look at the spectra of a natural sample of mirabilite, a salt that can form in cold and arid brine lakes, as a way to infer the geochemistry of ancient Mars.
