Evidence for Water at Meridiani
The Mars Exploration Rover Opportunity has examined sedimentary structures in the Burns formation at Meridiani Planum. The materials in this formation reflect, in part, subaqueous deposition of
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.

The layered deposits that comprise the Burns formation at Meridiani Planum have a chemical composition that closely resembles Martian basalts with addition of an oxidized sulfur component.
An interval of high salinity in ancient Gale crater lake on Mars
Precipitated minerals, including salts, are primary tracers of atmospheric conditions and water chemistry in lake basins. Ongoing in situ exploration by the Curiosity rover of Hesperian (around
Sedimentary textures formed by aqueous processes, Erebus crater, Meridiani Planum, Mars
New observations at Erebus crater (Olympia outcrop) by the Mars Exploration Rover Opportunity between sols 671 and 735 (a sol is a martian day) indicate that a diverse suite of primary and


In Situ Evidence for an Ancient Aqueous Environment at Meridiani Planum, Mars
The geologic record at Meridiani Planum suggests that conditions were suitable for biological activity for a period of time in martian history.
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.
Hematite on the Surface of Meridiani Planum and Gusev Crater
Meridiani Planum was selected as a landing side for the Rover Opportunity because of an indication of hematite observed from orbit. Meridiani Planum consists of sorted sands with aeolian features
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,
Formation of the hematite-bearing unit in Meridiani Planum: Evidence for deposition in standing water
[1] The most plausible models for the origin and evolution of a unique geologic unit in Meridiani Planum, Mars, are low-temperature precipitation of Fe oxides/oxyhydroxides from standing water,
Hydration state of the Martian coarse‐grained hematite exposures: Implications for their origin and evolution
[1] The discovery of areas of bulk gray hematite on the surface of Mars is among the most interesting of the results from Mars Global Surveyor (MGS). The individual outcrops are concentrated in
An integrated view of the chemistry and mineralogy of martian soils
It is shown 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, and Nickel abundances are enhanced at the immediate surface and indicate that the upper few millimetres of soil could contain up to one per cent meteoritic material.
