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, olivine-bearing basaltic soil, and a pyroxene-bearing basaltic rock (Bounce rock). Spherules, interpreted to be concretions, are hematite-rich and dispersed throughout the outcrop. Hematitic soils both within and outside Eagle crater are dominated by spherules and their fragments. Olivine-bearing basaltic soil… Expand
In Situ Evidence for an Ancient Aqueous Environment at Meridiani Planum, Mars
TLDR
The geologic record at Meridiani Planum suggests that conditions were suitable for biological activity for a period of time in martian history. Expand
Mineralogy at Meridiani Planum from the Mini-TES Experiment on the Opportunity Rover
TLDR
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.

Mössbauer Spectroscopy at Gusev Crater and Meridiani Planum
Mössbauer instruments were included on the Mars Exploration Rover (MER) Mission to determine the mineralogical composition, diversity, and oxidation state of Fe-bearing igneous materials andExpand
Transformation of jarosite to hematite in simulated Martian brines
The presence of jarosite – a hydrous iron sulfate – at Meridiani Planum supports the past existence of water on Mars surface. Thermodynamic calculations suggest that jarosite should transform toExpand
Two Years at Meridiani Planum: Results from the Opportunity Rover
TLDR
Observations from microscopic to orbital scales indicate that ancient Meridiani once had abundant acidic groundwater, arid and oxidizing surface conditions, and occasional liquid flow on the surface. Expand
Soils of Eagle Crater and Meridiani Planum at the Opportunity Rover Landing Site
TLDR
The soils at the Opportunity site are fine-grained basaltic sands mixed with dust and sulfate-rich outcrop debris and spherules emerge from soils coated, perhaps from subsurface cementation, by salts. Expand
Chemistry of Rocks and Soils at Meridiani Planum from the Alpha Particle X-ray Spectrometer
TLDR
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
Chemistry and mineralogy of outcrops at Meridiani Planum
Analyses of outcrops created by the impact craters Endurance, Fram and Eagle reveal the broad lateral continuity of chemical sediments at the Meridiani Planum exploration site on Mars. ApproximatelyExpand

The MER rover Opportunity has carried out the first outcrop-scale investigation of ancient sedimentary rocks on Mars. The rocks, exposed in craters and along fissures in Meridiani Planum, areExpand
Jarosite Occurrences in the MIL 03346 Nakhlite: Implications for Water on Mars
Nakhlites are basaltic martian meteorites that have been shown to contain aqueous alteration products (Treiman 2005). Among the alteration products is the mineral jarosite, which was discovered inExpand

The Opportunity Rover's Athena Science Investigation at Meridiani Planum, Mars
TLDR
The Mars Exploration Rover Opportunity has investigated the landing site in Eagle crater and the nearby plains within Meridiani Planum, and the rocks are interpreted to be a mixture of chemical and siliciclastic sediments formed by episodic inundation by shallow surface water, followed by evaporation, exposure, and desiccation.
