Estimating past fluid pH and evaporative conditions in Gale crater using terrestrial analog samples from Death Valley, CA

open access: yesMeteoritics &Planetary Science, EarlyView.
Abstract Boron and lithium have been observed in Ca‐sulfate veins of Gale crater. These elements are highly water mobile and can inform us regarding the aqueous processes that may have taken place in Gale crater. However, the analysis of B in Gale crater is limited to low‐Fe rocks and minerals due to spectral interference of Fe with B in ChemCam data ...
