- Data in this repository are included as main research results in the Journal of Geophysical Research: Planets manuscripts entitled: "Extensive diagenesis revealed by fine-scale features at Vera Rubin ridge, Gale crater, Mars" "A lacustrine paleoenvironment recorded at Vera Rubin ridge, Gale crater: Overview of the sedimentology and stratigraphy observed by the Mars Science Laboratory Curiosity rover". Table captions: Table 1. Murray formation targets from the Vera Rubin ridge used in the Gini mean index score (GIMS) analysis (sols 1808-2298) with summary information and GMEAN values with associated standard deviation errors. The grain size regimes (GSRs) were defined during the calibration procedure in Rivera-Hernández et al. (2020) and are defined as: mud (GMEAN=0.00-0.07; GSR1) and coarse silt to very fine sand (GMEAN=0.07-0.10; GSR2). Rocks with GMEAN=0.07 are exactly at GSR1 and GSR2 boundary and are reported as GSR1/GSR2. Next to the target names, the symbol * denotes that the ChemCam target was imaged by the Mars Hand Lens Imager (MAHLI), the symbol ** denotes that the dust removal tool was used before the MAHLI image was taken, and ~ signifies that a location close to the ChemCam target was imaged by the MAHLI. Table 2. The mean, median, minimum and maximum GMEAN and the minimum and maximum grain size regime (GSR) for each Murray formation locality in the Vera Rubin ridge.
