The Spirit landing site in Gusev Crater on Mars contains dark, fine-grained, vesicular rocks interpreted as lavas. Pancam and Mini-Thermal Emission Spectrometer (Mini-TES) spectra suggest that all of these rocks are similar but have variable coatings and dust mantles. Magnified images of brushed and abraded rock surfaces show alteration rinds and veins. Rock interiors contain </=25% megacrysts. Chemical analyses of rocks by the Alpha Particle X-ray Spectrometer are consistent with picritic… 

Fluid lava flows in Gusev crater, Mars

[1] Rocks on the floor of Gusev crater are basaltic in composition, as determined from measurements by the Mars Exploration Rover, Spirit. On the basis of compositional data, models of the basaltic

Chemistry of Rocks and Soils in Gusev Crater from the Alpha Particle X-ray Spectrometer

The alpha particle x-ray spectrometer on the Spirit rover determined major and minor elements of soils and rocks in Gusev crater in order to unravel the crustal evolution of planet Mars. The

Mineralogy at Gusev Crater from the Mössbauer Spectrometer on the Spirit Rover

The ubiquitous presence of olivine in soil suggests that physical rather than chemical weathering processes currently dominate at Gusev crater.

Alkaline volcanic rocks from the Columbia Hills, Gusev crater, Mars

[1] Irvine, Backstay, and Wishstone are the type specimens for three classes of fine-grained or fragmental, relatively unaltered rocks with distinctive thermal emission spectra, found as float on the

Initial Results from the Mini-TES Experiment in Gusev Crater from the Spirit Rover

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.

Geochemical properties of rocks and soils in Gusev Crater, Mars: Results of the Alpha Particle X-Ray Spectrometer from Cumberland Ridge to Home Plate

[1] Geochemical diversity of rocks and soils has been discovered by the Alpha Particle X-Ray Spectrometer (APXS) during Spirit's journey over Husband Hill and down into the Inner Basin from sol 470

Pyroclastic Activity at Home Plate in Gusev Crater, Mars

Textural observations indicate that the lower strata were emplaced in an explosive event, and geochemical considerations favor an explosive volcanic origin over an impact origin, so Home Plate likely represents accumulation of pyroclastic materials.

Hydrothermal origin of halogens at Home Plate, Gusev Crater

[1] In the Inner Basin of the Columbia Hills, Gusev Crater is Home Plate, an 80 m platform of layered clastic rocks of the Barnhill class with microscopic and macroscopic textures, including a bomb

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.

Textures of the soils and rocks at Gusev Crater from Spirit's Microscopic Imager.

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.

Localization and Physical Properties Experiments Conducted by Spirit at Gusev Crater

Physical properties experiments show a decrease of 0.2% per Mars solar day in solar cell output resulting from deposition of airborne dust, cohesive soil-like deposits in plains and hollows, bright and dark rock coatings, and relatively weak volcanic rocks of basaltic composition.
