Dataset for the manuscript Manganese-rich sandstones as an indicator of ancient oxic lake water conditions in Gale crater, Mars

This file is a csv file containing the average composition of rocks in the Murray formation in Gale crater, as determined by ChemCam, and metadata, for the manuscript Manganese-rich sandstones as an indicator of ancient oxic lake water conditions in Gale crater, Mars submitted to the Journal of Geophysical Research: Planets. The file contains the major oxide composition data for each observation point (comprised of at least 30 shots where the first 5 are removed due to Mars dust), the root mean squared error (RMSE) for each ChemCam observation point, and the standard deviation of the shot-to-shot data of that observation point (shot_stdev), and the sum of oxides of the observation point. The metadata includes the ‘Plot Label’ to indicate the category of the target (Dark Sandstones, Light Sandstones, Concretion, Other Diagenetic, Murray) as indicated in Figure 1 of the manuscript. The data was also used to produce Table 1. The filename, sol, spacecraft clock, target name, target distance from ChemCam, laser power, spectral totals, elevation, longitude, latitude, easting, northing, and notes metadata columns are provided for each observation point. The observations points are in order of ‘Plot Label’ and then by Spacecraft Clock.
