Critically testing olivine-hosted putative martian biosignatures in the Yamato 000593 meteorite - Geobiological implications

McLoughlin, Nicola; Grosch, Eugene Gerald; Vullum, Per Erik; Guagliardo, Paul; Saunders, Martin; Wacey, David (Journal article; Peer reviewed, 2019)

On rocky planets such as Earth and Mars the serpentinization of olivine in ultramafic crust produces hydrogen that can act as a potential energy source for life. Direct evidence of fluid–rock interaction on Mars comes from ...
On the biogenicity of Fe-oxyhydroxide filaments in silicified low-temperature hydrothermal deposits: Implications for the identification of Fe-oxidizing bacteria in the rock record

Johannessen, Karen Cecilie; McLoughlin, Nicola; Vullum, Per Erik; Thorseth, Ingunn Hindenes (Journal article; Peer reviewed, 2019)

Microaerophilic Fe(II)‐oxidizing bacteria produce biomineralized twisted and branched stalks, which are promising biosignatures of microbial Fe oxidation in ancient jaspers and iron formations. Extracellular Fe stalks ...
