Datasets of alteration features identified within the Bradbury Group, Murray formation and Stimson formation to sol 1482 in addition to the Vera Rubin Ridge locality. BedfordCandice 2019 Datasets of ChemCam observation point analyses that targeted the main alteration features in the Bradbury Group, Murray formation (to sol 1482 and on the Vera Rubin Ridge) and the Stimson formation. These data were used to derive the geochemical alteration trends of the main alteration feature groups in Bedford et al. (2019; https://doi.org/10.1016/j.gca.2018.11.031) and Bedford (2019) thesis chapters 3, 4, and 5.<div><br></div><div>This dataset excludes calibration targets, but includes observation point analyses with high and low totals (outside the 95-105 wt% range) to account for volatiles expected in such features (e.g., S or H).</div>
