Gini index mean score grain size estimates for Murray formation rocks in the Vera Rubin ridge (Gale crater, Mars) from ChemCam LIBS data (sols 1808-2298)

<p>Data in this repository are included as&nbsp;main research results in the Journal of Geophysical Research: Planets manuscripts entitled:</p> <p><em>&quot;</em>Extensive diagenesis revealed by fine-scale features at Vera Rubin ridge, Gale crater, Mars<em>&quot; </em></p> <p>&quot;A lacustrine paleoenvironment recorded at Vera Rubin ridge, Gale crater: Overview of the sedimentology and stratigraphy observed by the Mars Science Laboratory Curiosity rover&quot;.</p> <p>&nbsp;</p> <p><strong>Table captions:</strong></p> <p><em>Table 1.&nbsp;&nbsp;</em>Murray formation targets from the Vera Rubin ridge used in the Gini mean index score (GIMS) analysis&nbsp;(sols 1808-2298) with summary information and&nbsp;G_MEAN&nbsp;values with associated standard deviation errors. The grain size regimes (GSRs) were defined during the calibration procedure in Rivera-Hern&aacute;ndez et al. (2020)&nbsp;and are defined as: mud (G_MEAN=0.00-0.07; GSR1) and coarse silt to very fine sand (G_MEAN=0.07-0.10; GSR2). Rocks with G_MEAN=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.&nbsp;</p> <p><em>Table 2</em>.
