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 composition of soils is similar to those at previous landing sites, as a result of global mixing and distribution by dust storms. Rocks (fresh surfaces exposed by the rock abrasion tool) resemble volcanic rocks of primitive basaltic composition with low intrinsic potassium contents. High abundance of… 

Chemistry of Rocks and Soils at Meridiani Planum from the Alpha Particle X-ray Spectrometer

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.

Alteration Processes in Gusev Crater, Mars

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.

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.

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.

X-ray Diffraction Results from Mars Science Laboratory: Mineralogy of Rocknest at Gale Crater

The Mars Science Laboratory rover Curiosity scooped samples of soil from the Rocknest aeolian bedform in Gale crater that revealed plagioclase, forsteritic olivine, augite, and pigeonite, with minor K-feldspar, magnetite, quartz, anhydrite, hematite and ilmenite, which are similar to that found on Earth in places such as soils on the Mauna Kea volcano, Hawaii.
