Carbonate and phyllosilicate‐bearing aeolian bedforms proximal to margin fractured unit. (a) CRISM pixels (purple) for the spectra shown in panel (d). These pixels cover aeolian bedforms immediately west of the margin fractured bedrock shown in Figure S5 in Supporting Information S1. (b and c) Enlarged views of carbonate and phyllosilicate‐bearing aeolian bedforms. (d) UMass, TRR3, and TER CRISM spectra (purple) from purple pixels shown in panel (a) compared to library spectra (black). The spectral interpretation is the same as described in Figure 3. This aeolian material is therefore interpreted to derive from the proximal margin fractured unit bedrock.
