Mössbauer spectra measured on Mars by the Spirit rover during the primary mission are characterized by two ferrous iron doublets (olivine and probably pyroxene) and a ferric iron doublet (tentatively associated to nanophase ferric iron oxide). Two sextets resulting from nonstoichiometric magnetite are also present, except for a coating on the rock Mazatzal, where a hematite-like sextet is present. Greater proportions of ferric-bearing phases are associated with undisturbed soils and rock… 
Basaltic rocks analyzed by the Spirit Rover in Gusev Crater.
TLDR
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.
Magnetic properties of Martian olivine basalts studied by terrestrial analogues
Here we present a comparison study of terrestrial olivine basalt and relatively un-weathered basalt studied by the Mars Exploration Rover Spirit on Mars. The Mössbauer spectra of terrestrial olivine
High manganese concentrations in rocks at Gale crater, Mars
The surface of Mars has long been considered a relatively oxidizing environment, an idea supported by the abundance of ferric iron phases observed there. However, compared to iron, manganese is
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 and
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,
Mössbauer spectroscopy on Mars: goethite in the Columbia Hills at Gusev crater
In January 2004 the USA space agency NASA landed two rovers on the surface of Mars, both carrying the Mainz Mössbauer spectrometer MIMOS II. The instrument on the Mars-Exploration-Rover (MER) Spirit
Mössbauer and VNIR study of dust generated from olivine basalt: application to Mars
Mössbauer spectroscopy of surface rocks, soil, and dust on Mars from the Mars Exploration Rovers (MER) suggests that the mineral olivine is widespread on the surface. Detection of the mineral by
Weathering of Martian and Earth surface studied by Mössbauer spectroscopy
Martian regolith and Earth’s basaltoid samples have been investigated by means of Mössbauer spectroscopy. The identification of the same minerals: olivine, pyroxene, magnetite, hematite and

Initial Results from the Mini-TES Experiment in Gusev Crater from the Spirit Rover
TLDR
The Miniature Thermal Emission Spectrometer on Spirit has studied the mineralogy and thermophysical properties at Gusev crater and two spectrally distinct coatings are observed on rocks, a possible indicator of the interaction of water, rock, and airfall dust.
Magnetic Properties Experiments on the Mars Exploration Rover Spirit at Gusev Crater
The magnetic properties experiments are designed to help identify the magnetic minerals in the dust and rocks on Mars—and to determine whether liquid water was involved in the formation and
Oxidation State of Iron in SNC Meteorites as Studied by Mössbauer Spectroscopy
Mossbauer investigations of three meteorites of the type SNC-achondrites are reported. The results are compared with Mossbauer spectra of other meteorites, and selected terrestrial and lunar rocks.
The Spirit Rover's Athena science investigation at Gusev Crater, Mars.
TLDR
The Mars Exploration Rover Spirit and its Athena science payload have been used to investigate a landing site in Gusev crater, but no clear evidence for lacustrine sedimentation has been found to date.
Textures of the soils and rocks at Gusev Crater from Spirit's Microscopic Imager.
TLDR
The Microscopic Imager on the Spirit rover analyzed the textures of the soil and rocks at Gusev crater on Mars at a resolution of 100 micrometers, finding rock textures consistent with a volcanic origin and subsequent alteration and/or weathering by impact events, wind, and possibly water.
