    Squyres, Steven W.; Arvidson, Raymond E.; Ruff, S.; Gellert, R.; Morris, R. V.; Ming, D. W.; Crumpler, Larry S.; Farmer, J. D.; Marais, D. J. Des; Yen, A.; McLennan, S. M.; Calvin, W. M.; Bell, James F., III; Clark, Benton C.; Wang, A.; McCoy, Timothy J.; Schmidt, M. E.; de Souza, P. A., Jr. (2008)
    Mineral deposits on the martian surface can elucidate ancient environmental conditions on the planet. Opaline silica deposits (as much as 91 weight percent SiO2) have been found in association with volcanic materials by ...

(2008)
    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 to 1368. The APXS ...
  • Hydrothermal origin of halogens at Home Plate, Gusev Crater

    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 sag, suggestive of a ...
  • Hydrothermal processes at Gusev Crater: An evaluation of Paso Robles class soils 
    Yen, A. S.; Morris, R. V.; Clark, Benton C.; Gellert, R.; Knudson, A. T.; Squyres, Steven W.; Mittlefehldt, D. W.; Ming, D. W.; Arvidson, Raymond E.; McCoy, Timothy J.; Schmidt, M.; Hurowitz, J.; Johnson, J. (2008)

A.; McCoy, Timothy J.; Mittlefehldt, D. W.; Schmidt, M. E.; de Souza, P. A., Jr.; Squyres, Steven W. (2008)
    Spirit's Mossbauer (MB) instrument determined the Fe mineralogy and oxidation state of 71 rocks and 43 soils during its exploration of the Gusev plains and the Columbia Hills (West Spur, Husband Hill, Haskin Ridge, ...
  • Meteorites on Mars observed with the Mars Exploration Rovers 
    Schroeder, C.; Rodionov, D. S.; McCoy, Timothy J.; Jolliff, B. L.; Gellert, R.; Nittler, L. R.; Farrand, W. H.; Johnson, J. R.; Ruff, S. W.; Ashley, J. W.; Mittlefehldt, D.

S.; Zipfel, J.; Economou, T. (2008)
    Reduced weathering rates due to the lack of liquid water and significantly greater typical surface ages should result in a higher density of meteorites on the surface of Mars compared to Earth. Several meteorites were ...
  • Mineralogy of volcanic rocks in Gusev Crater, Mars: Reconciling Mossbauer, Alpha Particle X-ray spectrometer, and Miniature Thermal Emission Spectrometer spectra 
    McSween, Harry Y.; Ruff, S. W.; Morris, R. V.; Gellert, R.; Klingelhöfer, Göstar; Christensen, Philip R.; McCoy, Timothy J.; Ghosh, A.; Moersch, J. M.; Cohen, B. A.; Rogers, A. D.; Schroder, C.; Squyres, Steven W.; Crisp, J.; Yen, A. (2008)
