Cross section of carbonate‐bearing rocks inside Jezero crater. (a) HiRISE DTM (Fergason et al., 2020) of carbonate‐bearing rocks in Jezero crater in the margin fractured unit. The green and blue colors are CRISM pixel clusters from which the spectra in panel (c) were extracted. (b) Elevation profile of cross section shown in panel (a), with the areas covered by the CRISM pixel clusters labeled. (c) CRISM spectra (blue and green) of the pixel clusters shown in panel (a) compared to library spectra (black), showing that this entire outcrop cross section is carbonate‐bearing.
