Bacterially-Mediated Formation of Rock Coatings in Kärkevagge, Swedish Lapland: A Mineralogical and Micro-Environmental Analog for Mars
… preserve evidence of that life is that of rock coatings. Rock coatings are mineral accretions on rock surfaces. On Earth, they are widespread and occur with considerable chemical diversity. There is growing evidence for a biotic role in their formation on Earth, particularly with respect to …

Studying signatures of water on Mars at two macro and micro scales : orbital analyses of hillslope geomorphology and ChemCam calibration for surficial rock chemistry
… second set of studies, carbonate minerals and rock coatings and rinds were measured by LIBS in a simulated martian environment to better understand the signature of these materials on Mars. This work is in preparation for the Mars Science Laboratory (MSL) rover mission, in which a LIBS …

Effect of halite and calcite coatings on thermal infrared spectra wih implications for Mars exploration
… of surface solutions on Mars. Salts deposited as coatings are particularly important for attaining this knowledge because the thermal infrared (TIR) remote sensing method for determining mineral abundance is limited to the top few hundred micrometers of the surface. To better understand the TIR …
