Mineralogical and Geochemical Trends of the Murray Mudstones, Gale Crater: A Combined Sample Analysis at Mars-Evolved Gas Analyzer and Chemistry and Mineralogy Instrument Assessment

Abstract: The Murray formation is predominantly composed of lacustrine mudstone that forms the basal layer of Aeolis Mons (informally Mt. Sharp) in Gale Crater, Mars. The Murray formation has distinct iron and sulfur mineralogical variation within its stratigraphy detectable by the Chemistry Mineralogy (Che-Min) instrument consisting of magnetite/hematite in the lower Murray and higher hematite, CaSO4, and smectite content in the upper Murray. The objectives of this work were to evaluate the Sample Ana…
