CRISM mapping reveals Pre-/Early-Noachian alteration is discontinuous in the crust. Higher temperature alteration assemblages occur in Eastern Coprates Chasma. Assemblage constrains lateral offset of Valles Marineris to less than ∼25–50 km. Evidence for thrust faulting in western Coprates Chasma with compositional mapping. Diverse Noachian primary mineralogy (LCP dominates, +/− plagioclase and olivine).
