• Alpha Particle X‐Ray Spectrometer (APXS): Results from Gusev crater and calibration report (2006, methodology): “[68] For the Mars Pathfinder mission, a similar Cl content was found for the derived soil-free rock composition of Ares Vallis [Brückner et al., 2003; Foley et al., 2003b].”
• Mineralogy and evolution of the surface of Mars: A review (2007, background): “Indeed, the Martian regolith contains about 20wt% Fe (Bell III et al., 2000; Foley et al., 2003; Rieder et al., 1997) mostly under the form of iron oxides and (oxy)hydroxides.”
• Identification of quartzofeldspathic materials on Mars (2004, background): “Alpha proton X-ray spectrometer results also suggest andesitic compositions at the Mars Pathfinder landing site [McSween et al., 1999; Foley et al., 2003].”
• Bacterial Iron Oxidation in Circumneutral Freshwater Habitats: Findings from the Field and the Laboratory (2004, background): “Current theories on the formation of Fe(III)-rich Martian soils invoke weathering of basalts through hydrothermal processes, volcanization, or palagonization, ie, the process of rapid cooling and mineral exchange that occurs when volcanic basalts come in contact with water ( McSween and Keil 2000 ; ”
• Global distribution of near-surface hydrogen on Mars (2004, methodology): “…(APXS) data from Mars Pathfinder used stoichiometry arguments to estimate H2O abundances from observed excess oxygen, yielded an average H2O mass fraction for soils ranging up to 1.7% (but generally desiccated), and for rocks ranging between 0.1 ± 1.3% and 4.3 ± 1.3% [Foley et al., 2003].”
• Equatorial and midlatitude distribution of chlorine measured by Mars Odyssey GRS (2007, background): “both elements have been measured at the landing sites [Brückner et al., 2003; Clark et al., 1982; Foley et al., 2003; Gellert et al., 2004; Rieder et al., 2004; Wänke et al., 2001].”
