APXS derived geochemistry of shallow water lens bodies within the Mirador formation, Gale crater, Mars – Evidence for intermittent wet periods and implications for the water record - Supplemental Data Files

Table S1. Compositional Data. (S1a) APXS compositional data for targets from sol 3078 to sol 4028; (S1b) Percentage change relative to mean Mount Sharp group (pre-Marker Band Valley). All data reported as wt. % except Ni, Zn, Br (ppm). Error = 2σ statistical precision error. Table S2. Average calculations. (S2a) Summary of results. (S2b) Contigo interdune lenses, Mirador fm. (S2c) Mount Sharp group (sols 722-3532). (S2d) Clay Sulfate Transition (CST) (sols 3085-3712). (S2e) Chenapau mbr, Mirador fm above Amapari Marker Band. (S2f), Contigo mbr in Marker Band Valley and Catrimani mbr in Marker Band Valley; both Mirador fm, below Amapari Marker Band Valley. Table S3. Variance analysis. (S3a) Summary of results. (S3b). Calculations, including: Kruskal-Wallis test; Welch’s test; Levene’s Test; Games Howell post-hoc test; Q-test results. (S3c) List of included targets. Table S4. Two- and three-end member Iterative modeling calculations. (S4a) Summary of results. (S4b) Three-end member model: Mirador fm (pre-Marker Band Valley) (MBV) plus Gale sands (active) plus dust. (S4c) Three-end member model: Clay Sulfate Transition (CST) (excluding MBV) plus Gale sands (active) plus dust. (S4d) Two-end member model: Mirador fm (pre-MBV) plus Naukluft Plateau (Stimson fm). (S4e) Two-end member model: Mirador fm (pre-MBV) plus Emerson Plateau (Stimson fm). (S4f) Two-end member model: CST (excluding MBV) plus Naukluft Plateau (Stimson fm). (S4g) Two-end member model: CST (pre-MBV) plus Emerson Plateau (Stimson fm).
