Shield, high molecular weight hydrocarbons, fatty alcohols, and fatty acids found in fracture calcites have been proposed to fuel microbial methanogenesis18and dominantly heterotrophic microbial communities in deep fluids supported by organics from black schist and other metasedimentary rocks or ...
The presence of ‘younger’ material suggests temporary preservation of either transported surface-derived or recently formed organic matter on rock surfaces rather than chemical bonding to material co-originating with the rock matrix. The high amounts of ‘younger’ material leached from rocks of the...
"What SHERLOC adds to the story is its capability to map the spatial distribution of organics inside rocks and relate those organics to minerals found there," he added. "This helps us understand the environment in which the organics formed." Related: The search for life on Mars (a photo ti...
During diagenesis, the “geopolymers” thus formed continuously undergo chemical transformations by which they become more and more insoluble and resistant. Kerogens are being formed, which—depending on the nature of the original organic matter contributions—can generate various amounts and sorts of ...
The process by which nuclei are formed in solution. Short-range-ordered The regular and predictable arrangement of atoms over a very short distance; in crystals, order does not persist over distances of more than a few nanometres and often extends over a distance of just a few bond lengths;...
72 found that by adding molecular oxygen, sulfur and nitrogen compounds to biphenyl (BP), large quantities of DBF, dibenzothiophene (DBT) and carbazole were produced due to the effects of activated carbon, and the resulting compounds formed in proportion to the amounts of O, S and N in the...
