Global Mineralogical and Aqueous Mars History Derived from OMEGA/Mars Express Data
Global mineralogical mapping of Mars by the Observatoire pour la Mineralogie, l'Eau, les Glaces et l'Activité (OMEGA) instrument on the European Space Agency's Mars Express spacecraft provides new…

Sulfates in Martian Layered Terrains: The OMEGA/Mars Express View
TLDR
Outcrops in Valles Marineris, Margaritifer Sinus, and Terra Meridiani show evidence for kieserite, gypsum, and polyhydrated sulfates, which constitute direct records of the past aqueous activity on Mars.

Mars Surface Diversity as Revealed by the OMEGA/Mars Express Observations
TLDR
The OMEGA investigation, on board the European Space Agency Mars Express mission, has identified and mapped mafic iron-bearing silicates of both the northern and southern crust, localized concentrations of hydrated phyllosilicates and sulfates but no carbonates, and ices and frosts with a water-ice composition of the north polar perennial cap.

Phyllosilicates on Mars and implications for early martian climate
TLDR
It is inferred that the two main families of hydrated alteration products detected—phyllosilicates and sulphates—result from different formation processes, which occurred during two distinct climatic episodes: an early Noachian Mars, resulting in the formation of Hydrated silicates, followed by a more acidic environment, in which sulphates formed.

Jarosite and Hematite at Meridiani Planum from Opportunity's Mössbauer Spectrometer
Mössbauer spectra measured by the Opportunity rover revealed four mineralogical components in Meridiani Planum at Eagle crater: jarosite- and hematite-rich outcrop, hematite-rich soil,…

Impact craters and Venus resurfacing history
Venusian impact crater size-frequency distributions, locations, and preservation states were analyzed to reconstruct the history of resurfacing by tectonism and volcanism. An atmospheric transit…
