Several different phyllosilicates are observed, with inferred accompanying phases ranging from zeolites to sulfates to chlorides, each in distinct geologic settings. Hydrated sulfates are observed in several locations at mid-latitudes, and likely formed independently from the equatorial sulfates. These assemblages suggest a greater diversity of aqueous environments on ancient Mars than has previously been recognized, and their distribution implies that alteration was widespread during the Noachian Period, not restricted to a few locations.
