Evaporative Salts from Saline Lakes on Tibet Plateau: an Analog for Salts on Mars,
Martian salts: Salts have been identified on Mars by spectrometers on orbiters and rovers. Among them, Mg-, Ca-, and Fesulfates were identified or implied in Meridiani outcrop [1] and in Gusev salty soils and rocks [2,3]; kieserite (MgSO4.H2O) and “polyhydrated sulfates” were found in Valley Marineris, Meridiani Planum, and gypsum (CaSO4.2H2O) near North Pole [4,5,6,7]. Recently, chloride-beari...
متن کاملAlteration of immature sedimentary rocks on Earth and Mars: Recording aqueous and surface–atmosphere processes
a r t i c l e i n f o a b s t r a c t Rock alteration and rind formation in analog environments like Antarctica may provide clues to rock alteration and therefore paleoclimates on Mars. Clastic sedimentary rocks derived from basaltic sources have been studied in situ by martian rovers and are likely abundant on the surface of Mars. However, how such rock types undergo alteration when exposed to...
متن کاملThermal Emission Spectroscopy of Zeolite Minerals
Introduction and background: Zeolite minerals are hydrated framework aluminosilicates common to altered volcanic and volcanoclastic rocks, and the soils derived from them [1]. The mineralogy, chemistry, textural context, and abundance of zeolites provides insight into chemical weathering, hydrothermal, and metamorphic processes on Earth, in a variety of climates and tectonic settings. Zeolites ...
متن کاملDepth selective Mössbauer spectroscopy: Analysis and simulation of 6.4 keV and 14.4 keV spectra obtained from rocks at Gusev Crater, Mars, and layered laboratory samples
[1] The miniaturized Mössbauer spectrometer (MIMOS) II Mössbauer spectrometers on the Mars Exploration Rovers (MER) simultaneously obtained 6.4 keV and 14.4 keV Mössbauer spectra from rock and soil targets. Because photons with lower energy have a shallower penetration depth, 6.4 keV spectra contain more mineralogical information about the near-surface region of a sample than do 14.4 keV spectr...
متن کاملSynthesis of a spinifex-textured basalt as an analog to Gusev crater basalts, Mars
Analyses by the Mars Exploration Rover (MER), Spirit, of Martian basalts from Gusev crater show that they are chemically very different from terrestrial basalts, being characterized in particular by high Mgand Fe-contents. To provide suitable analog basalts for the International Space Analogue Rockstore (ISAR), a collection of analog rocks and minerals for preparing in situ space missions, espe...
