Journal ArticleDOI
Phyllosilicate diversity and past aqueous activity revealed at Mawrth Vallis, Mars
Janice L. Bishop,Eldar Noe Dobrea,Nancy K. McKeown,Mario Parente,Bethany L. Ehlmann,Joseph R. Michalski,Ralph E. Milliken,François Poulet,Gregg A. Swayze,John F. Mustard,Scott L. Murchie,Jean-Pierre Bibring +11 more
TL;DR: The stratigraphy of Fe/Mg-smectite overlain by a ferrous phase, hydrated silica, and then Al-phyllosilicates implies a complex aqueous history, which could be explained here by hydrothermal activity.
Journal ArticleDOI
Groundwater activity on Mars and implications for a deep biosphere
Joseph R. Michalski,Joseph R. Michalski,Javier Cuadros,Paul B. Niles,John Parnell,A. Deanne Rogers,S. P. Wright +6 more
TL;DR: In this article, an evaluation of the possibility of groundwater upwelling, which might provide clues to subsurface habitability, reveals evidence in the deep McLaughlin crater for clays and carbonates that probably formed in an alkaline, groundwater-fed lacustrine setting.
Journal ArticleDOI
In-Situ and Experimental Evidence for Acidic Weathering of Rocks and Soils on Mars
Joel A. Hurowitz,Scott M. McLennan,Nicholas J. Tosca,Raymond E. Arvidson,Joseph R. Michalski,Douglas W. Ming,Christian Schröder,Steven W. Squyres +7 more
TL;DR: In this paper, a model for rock surface alteration is developed which indicates that a leached alteration zone is present on rock surfaces at Gusev, and the chemistry of rock surfaces analyzed after brushing with the RAT is largely representative of the leached zone.
Journal ArticleDOI

TL;DR: Gale Crater was selected as the Mars Science Laboratory landing site based on diversity, context, and biosignature preservation as mentioned in this paper, and the final four sites have layered sedimentary rocks with spectral evidence for phyllosilicates.
Journal ArticleDOI
Deep crustal carbonate rocks exposed by meteor impact on Mars
TL;DR: In this article, Spectral analyses of rocks exposed from deep within an impact crater reveal that carbonate deposits may have once had a CO2-rich atmosphere, but carbonate rocks that could provide evidence for such conditions are sparse.
