TRANSCRIPT
Contact between putative delta and brecciated substrate in western Eberswalde CraterLatitude/longitude: -23.784 North, 326.481 East
Rationale:Phyllosilicate-bearing, putative delta deposits onlap older rocks interpreted as impact megabreccia.
Morphology and Mineralogy: The brecciated, ridge-forming deposit contains light-toned veins and Fe-bearing phyllosilicate signatures in CRISM spectra. The light-toned, fractured, layered rocks at the terminus of the putative delta have CRISM spectra consistent with phyllosilicates and pyroxene (Milliken, 4th MSL Workshop Presentation, 2010).
What will the rover specifically do here?Characterize the composition and small-scale textures of layered rock; study the composition of light-toned veins; characterize the lithology of the brecciated substrate.
