Supplementary Figure 8 | Carbonate, hydrated silica, phyllosilicate, and olivine-bearing rock in the crater floor fractured 2 unit. (a) Overview figure showing regional context of extracted CRISM spectra. (b) CRISM pixels (green) for spectra in (d) are shown in green. These pixels cover the crater floor fractured 2 unit. (c) Enlarged view of crater floor fractured 2 unit bedrock overlain by dark-toned material and aeolian bedforms. (d) UMass, TRR3, And TER CRISM spectra of pixels shown in (b). The absorption features are consistent with those described in Figure 12, and the compositional interpretation is the same. The geologic context is similar to that described in Figure 14, where dark-toned unconsolidated material and aeolian bedforms comprise the majority of the area covered by the CRISM data. This dark-toned unconsolidated material may be locally derived, in which case it has the same composition as the bedrock. Alternatively, this material may be the silica-rich material—described by Tarnas et al. (2019) and reported in Figures 15, 16, and S9 in this work—spectrally mixing with olivine, carbonate, and phyllosilicate-bearing bedrock in the crater floor fractured 2 unit.
