The Miniature Thermal Emission Spectrometer (Mini-TES) on Spirit has studied the mineralogy and thermophysical properties at Gusev crater. Undisturbed soil spectra show evidence for minor carbonates and bound water. Rocks are olivinerich basalts with varying degrees of dust and other coatings. Dark-toned soils observed on disturbed surfaces may be derived from rocks and have derived mineralogy (±5 to 10%) of 45% pyroxene (20% Ca-rich pyroxene and 25% pigeonite), 40% sodic to intermediate… 

Basaltic rocks analyzed by the Spirit Rover in Gusev Crater.

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.

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.
