Supplementary Figure 9 | Smooth dark-toned silica-bearing material overlying crater floor fractured unit. (a) CRISM pixels (blue) for the spectra shown in (d). These pixels cover the smooth dark-toned material reported to be silica-bearing by Tarnas et al. (2019). (b) Enlarged view of smooth dark-toned silica-bearing material overlying the crater floor fractured unit. (c) Another enlarged view of smooth dark-toned silica-bearing material overlying the crater floor fractured unit. (d) UMass, TRR3, And TER CRISM spectra from blue pixels shown in (a). These spectra are consistent with hydrated silica and the Jezero crater hydrated silica detections reported in this material in different locations by Tarnas et al. (2019).
