VNIR carbonate spectra from within and outside of Jezero crater. (a) Overview of investigated area in the Nili Fossae region. (b) Enlarged view of box from panel (a) showing CRISM pixels (red) associated with the corresponding numbered carbonate‐bearing spectra in panel (f) extracted from outside of Jezero crater. The combined coverage of the analyzed CRISM images in this area (FRT0000C256, FRT000095FE, and FRT000028BA) is outlined in black. (c) Same as panel (b), but for CRISM image FRT0000C968. (d) Same as panel (b), but for CRISM image FRT00016A73. (e) Same as panel (b), but for carbonate‐bearing spectra extracted both from outside (13–14) and inside (15–27) Jezero crater from CRISM image HRL000040FF. (f) The CRISM spectra extracted from each labeled pixel cluster in panels (b)–(e) compared to mineral spectra measured in the laboratory (black). These spectra show evidence for carbonate, Fe/Mg‐phyllosilicate, olivine, and either hydrated silica or Al‐phyllosilicate. The carbonate spectra extracted from within and outside of Jezero crater are also qualitatively similar.
