Datafromthe Observatoire pour la Minéralogie, l'Eau, les Glaces, et l'Activité (OMEGA) on the Mars Express spacecraft identify the distinct mafic, rock-forming minerals olivine, low-calcium pyroxene (LCP), and high-calcium pyroxene (HCP) on the surface of Mars. Olivine- and HCP-rich regions are found in deposits that span the age range of geologic units. However, LCP-rich regions are found only in the ancient Noachian-aged units, which suggests that melts for these deposits were derived from… 

Phyllosilicates on Mars and implications for early martian climate

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.

Olivine dissolution by acidic fluids in Argyre Planitia, Mars: Evidence for a widespread process?

Compositional and morphological analyses of basin rim units in Argyre Planitia are con- sistent with local olivine-rich materials that become relatively olivine-poor in the process of being

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

Mineralogy of the Martian Surface

The past fifteen years of orbital infrared spectroscopy and in situ exploration have led to a new understanding of the composition and history of Mars. Globally, Mars has a basaltic upper crust

Opaline silica in young deposits on Mars

High spatial and spectral resolution reflectance data acquired by the Mars Reconnaissance Orbiter Compact Reconnaissance Imaging Spectrometer for Mars (CRISM) instrument reveal the presence of H_2O-

Aqueous environmental history of Mars revealed by mineralogy and geochemistry of outcrop exposures of sedimentary rocks

Recent high-resolution spectral images and in-situ observations have revealed more than 1000 outcrops of diverse aqueous mineral deposits on Mars. Layered deposits of phyllosilicates (and carbonates)

Hydrated silicate minerals on Mars observed by the Mars Reconnaissance Orbiter CRISM instrument

The diversity of phyllosilicate mineralogy is expanded with the identification of kaolinite, chlorite and illite or muscovite, and a new class of hydrated silicate (hydrated silica).

Evidence for magmatic evolution and diversity on Mars from infrared observations

Observations show that the martian crust, while dominated by basalt, contains a diversity of igneous materials whose range in composition from picritic basalts to granitoids rivals that found on the Earth.



Basaltic rocks analyzed by the Spirit Rover in Gusev Crater.

Chemical analyses of rocks by the Alpha Particle X-ray Spectrometer are consistent with picritic basalts, containing normative olivine, pyroxenes, plagioclase, and accessory FeTi oxides, which extend the known range of rock compositions composing the martian crust.

Seeing through the dust: martian crustal heterogeneity and links to the SNC meteorites

It is possible to infer, even through the veil of dust, that the SNC meteorites have mineralogic affinities to major volcanic provinces on Mars and are therefore truly representative of the heterogeneity observed on the surface of the "red planet".

A Global View of Martian Surface Compositions from MGS-TES

Thermal Emission Spectrometer (TES) data from the Mars Global Surveyor (MGS) are used to determine compositions and distributions of martian low-albedo regions. Two surface spectral signatures are

Discovery of Olivine in the Nili Fossae Region of Mars

We have detected a 30,000-square-kilometer area rich in olivine in the Nili Fossae region of Mars. Nili Fossae has been interpreted as a complex of grabens and fractures related to the formation of

Constraints on the composition and petrogenesis of the Martian crust

[1] Spectral interpretation that silicic rocks are widespread on Mars implies that Earth's differentiated crust is not unique. Evaluation of observations bearing on the composition of the Martian

Mars Surface Diversity as Revealed by the OMEGA/Mars Express Observations

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.

Spectral evidence for weathered basalt as an alternative to andesite in the northern lowlands of Mars

The results continue to indicate the dominance of unaltered basalt in the southern highlands, but reveal that the northern lowlands can be interpreted as weathered basalt as an alternative to andesite.

Effects of pure silica coatings on thermal emission spectra of basaltic rocks: Considerations for Martian surface mineralogy

On Mars, silica derived from chemical weathering could precipitate to coat rocks and particles. We suggest that rock coatings of secondary amorphous silica may account for a widespread Martian

Searching for the source regions of martian meteorites using MGS TES: Integrating martian meteorites into the global distribution of igneous materials on Mars

Abstract— The objective of this study was to identify and map possible source regions for all 5 known martian meteorite lithologies (basalt, lherzolite, clinopyroxenite, orthopyroxenite, and dunite)

Effects of glass content and oxidation on the spectra of SNC-like basalts: Applications to Mars remote sensing
