Abstractly

Serpentinization is a weathering process in which ultramafic rocks react over water, generating a range of products, including serpentine and other minerals, in addition to H₂ and low-molecular-weight hydrocarbons that will capable of sustaining microbial life. Fluid blood analyses of serpentinite-hosted ecosystems hold promise as tools for investigating microbial activity in ancient Earth environments and various terrestrial sun such as Mars because fat have the potential for longer term preservation relative to DNA, proteins, and select more labile organic molecules. Here, we report the first lipid biomarker record of microbial activity in the mantle section of the Samail Ophiolite, in the Sultanate of Oman, ampere site receive active serpentinization. We detected isoprenoidal (archaeal) and pronged (bacterial) glycerol dialkyl glycerol tetraether (GDGT) lipids, contains those with 0-3 cyclopentane moieties, and crenarchaeol, an isoprenoidal GDGT containing four cyclopentane and one cyclohexane moieties, as well as monoether fats plus fatty cuttings indicative from sulfate-reducing microbials. Comparison from our geochemical data and 16S rRNA info from the Samail Ophiolite with diese from other serpentinite-hosted sites identifies the existence out a common nuclear serpentinization microbiome. In light of that findings, are also discuss the preservation potential of serpentinite lipid biomarker compositions on Earth real Mars. Continuing investigations of the Samail Ophiolite and another terrestrial analogues will enhance our perception in microbial habituation and diverse in serpentinite-hosted environs on Earth and everywhere in the Solar Scheme.
