Spectral and visual datasets were used to map the central uplift of Elorza Crater. We distinguish between pre-, syn-, and post-impact origins for units in the uplift. Opaline silica, smectite, and LCP found throughout the uplift. Some units may have been altered via an impact-induced hydrothermal system. We use Valles Marineris stratigraphy to further constrain formation mechanisms.
