Clay mineralogy in west Chryse Planitia, Mars: Supporting Datasets

This repository contains the supporting materials associated with Brossier et al. (202x), submitted to journal (DOI) - it includes: [outcrops.shp] - shapefiles (and auxiliary files) for all clay outcrops mapped in the studied areas (Lunae Planum and Tempe Terra), through 14 CRISM hyperspectral targeted cubes. These outcrops were mapped using the index maps showing pixels with strong absorptions near 1.9 and 2.3 microns, and therefore most consistent with the presence of clays. [CRISM_spectra.txt] - Text file including the denoised reflectance (I/F) values for the CRISM spectra of the clay-bearing outcrops in Lunae Planum and Tempe Terra. All spectra are smoothed and normalized for a better comparison.  Note: All imagery and altimetry datasets are available through the NASA PDS server (see link below).
