Chemolithotrophy on the Noachian Martian breccia NWA 7034 via experimental microbial biotransformation

چکیده

Abstract Multiple lines of evidence indicate an active hydrogeological history Mars and chemolithoautotrophy-suited environments within its Noachian terrains. As a result, one the primary aims upcoming missions to is search for signs ancient life. Here we report on laboratory-scaled microbially assisted chemolithoautotrophic biotransformation Martian breccia Northwest Africa (NWA) 7034 composed (~4.5 Gyr old) crustal materials from Mars. Nanoanalytical hyperspectral analysis provides clues trafficking distribution meteorite inorganic constituents in microbial cell. We decipher biomineralization patterns associated with reveal nanometer-sized lithologies located inside cell outer surface layer. These investigations provide opportunity trace putative bioalteration processes crust assess potential biogenicity materials.

Evidence for a widespread basaltic breccia component in the martian low-albedo regions from the reflectance spectrum of Northwest Africa 7034

Northwest Africa (NWA) 7034 is the first breccia meteorite from Mars, and unlike the shergottite, nakhlite, and chassignite (SNC) martian meteorites, it matches the estimated chemical composition of martian crust. Here we show that the visible-infrared reflectance spectrum of NWA 7034 is unique compared to other SNCs and is more similar than them to remotely sensed data from Mars, suggesting th...

Unique meteorite from early Amazonian Mars: water-rich basaltic breccia Northwest Africa 7034.

We report data on the martian meteorite Northwest Africa (NWA) 7034, which shares some petrologic and geochemical characteristics with known martian meteorites of the SNC (i.e., shergottite, nakhlite, and chassignite) group, but also has some unique characteristics that would exclude it from that group. NWA 7034 is a geochemically enriched crustal rock compositionally similar to basalts and ave...
