  • Evidence for mechanical and chemical alteration of iron-nickel meteorites on Mars: Process insights for Meridiani Planum 
    Ashley, J. W.; Golombek, M. P.; Christensen, Philip R.; Squyres, Steven W.; McCoy, Timothy J.; Schroeder, C.; Fleischer, I.; Johnson, J. R.; Herkenhoff, Kenneth E.; Parker, T. J. (2011)
    The weathering of meteorites found on Mars involves chemical and physical processes that can provide clues to climate conditions at the location of their discovery. Beginning on sol 1961, the Opportunity rover encountered ...
  • Geochemical properties of rocks and soils in Gusev Crater, Mars: Results of the Alpha Particle X-Ray Spectrometer from Cumberland Ridge to Home Plate 
    Ming, D. W.; Gellert, R.; Morris, R. V.; Arvidson, Raymond E.; Bruekner, J.; Clark, Benton C.; Cohen, B. A.; d'Uston, C.; Economou, T.; Fleischer, I.; Klingelhöfer, Göstar; McCoy, Timothy J.; Mittlefehldt, D. W.; Schmidt, M. E.; Schroeder, C.; Squyres, Steven W.; Treguier, E.; Yen, A. S.; Zipfel, J. (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 
    Schmidt, M. E.; Ruff, S. W.; McCoy, Timothy J.; Farrand, W. H.; Johnson, J. R.; Gellert, R.; Ming, D. W.; Morris, R. V.; Cabrol, Nathalie A.; Lewis, K. W.; Schroeder, C. (2008)
    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 ...
  • Iron mineralogy and aqueous alteration from Husband Hill through Home Plate at Gusev Crater, Mars: Results from the Mossbauer instrument on the Spirit Mars Exploration Rover 
    Morris, R. V.; Klingelhöfer, Göstar; Schroeder, C.; Fleischer, I.; Ming, D. W.; Yen, A. S.; Gellert, R.; Arvidson, Raymond E.; Rodionov, D. S.; Crumpler, Larry S.; Clark, Benton C.; Cohen, B. 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. W.; Herkenhoff, Kenneth E.; Fleischer, I.; Haldemann, A. F. C.; Klingelhöfer, Göstar; Ming, D. W.; Morris, R. V.; de Souza, P. A.; Squyres, Steven W.; Weitz, Catherine M.; Yen, A. 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 ...
