The mineralogical and elemental compositions of the martian soil are indicators of chemical and physical weathering processes. Using data from the Mars Exploration Rovers, we show that bright dust deposits on opposite sides of the planet are part of a global unit and not dominated by the composition of local rocks. Dark soil deposits at both sites have similar basaltic mineralogies, and could reflect either a global component or the general similarity in the compositions of the rocks from which… Expand

The role of aqueous alteration in the formation of martian soils
Abstract Martian equatorial dark regions are dominated by unweathered materials and it has often been assumed that they have not been significantly altered from their source lithology. The suite ofExpand

On the in situ aqueous alteration of soils on Mars
Abstract Early (>3 Gy) wetter climate conditions on Mars have been proposed, and it is thus likely that pedogenic processes have occurred there at some point in the past. Soil and rock chemistry ofExpand
Elemental Geochemistry of Sedimentary Rocks at Yellowknife Bay, Gale Crater, Mars
The absence of predicted geochemical variations indicates that magnetite and phyllosilicates formed by diagenesis under low-temperature, circumneutral pH, rock-dominated aqueous conditions during the early history of Mars. Expand
No Martian soil component in shergottite meteorites
Abstract We report on the major and trace element geochemistry of the impact melts contained in some shergottite meteorites. It has been previously proposed that some of these impact melts formedExpand


Spectroscopic evidence for hydrous iron sulfate in the Martian soil
[1] Despite in situ analyses by several landers, the composition of the Martian soil remains unclear. Recently, constituent minerals in the soil have been proposed from thermal emissivity andExpand
Chemistry of Rocks and Soils at Meridiani Planum from the Alpha Particle X-ray Spectrometer
The Alpha Particle X-ray Spectrometer on the Opportunity rover determined major and minor elements of soils and rocks in Meridiani Planum, indicating the interaction with water in the past is indicated by the chemical features in rocks and soils. Expand
Mineralogy at Meridiani Planum from the Mini-TES Experiment on the Opportunity Rover
The Miniature Thermal Emission Spectrometer on Opportunity investigated the mineral abundances and compositions of outcrops, rocks, and soils at Meridiani Planum, finding Bounce rock is dominated by clinopyroxene and is close in inferred mineral composition to the basaltic martian meteorites.

Chemical Composition of Martian Soil and Rocks: Complex Mixing and Sedimentary Transport
Chemical compositions of Martian soil and rocks indicate complex mixing relationships. Mixing of rock and soil clearly takes place and explains some of the chemical variation because sulfur,Expand
An assessment of the meteoritic contribution to the Martian soil
The addition of meteoritic material to the Mars soils should perturb their chemical compositions, as has been detected for soils on the Moon [Anders et al., 1973] and sediments on Earth [Kyte andExpand
Is the Martian lithosphere sulfur rich
It is proposed that the high sulfur measured in Martian fines may represent more than enrichment by upward migration of soluble sulfate salts. It may in fact reflect intrinsic surface abundances of SExpand
