The rocky road to organics needs drying
Autor: Muriel Andreani, Gilles Montagnac, Clémentine Fellah, Jihua Hao, Flore Vandier, Isabelle Daniel, Céline Pisapia, Jules Galipaud, Marvin D. Lilley, Gretchen L. Früh Green, Stéphane Borensztajn, Bénédicte Ménez
Publikováno v: Nature Communications, Vol 14, Iss 1, Pp 1-12 (2023)
How complex organics form in a prebiotic world remains a missing key to establish where life emerged. The authors present a road to abiotic organic synthesis and diversification in hydrothermal contexts involving magmatism and rock hydration.

Abiotic formation of condensed carbonaceous matter in the hydrating oceanic crust
Autor: Marie Catherine Sforna, Daniele Brunelli, Céline Pisapia, Valerio Pasini, Daniele Malferrari, Bénédicte Ménez
Publikováno v: Nature Communications, Vol 9, Iss 1, Pp 1-8 (2018)
Thermodynamic calculations suggest that condensed carbonaceous matter should be the dominant product of abiotic organic synthesis during serpentinization of the oceanic crust at Mid-Ocean Ridges. Here the authors report natural occurrences of such ca

Stromatolites are organo-sedimentary structures that represent some of the oldest records of the early biosphere on Earth. Cyanobacteria are considered as a main component of the microbial mats that are supposed to produce stromatolite-like structure

Publikováno v: Science advances. 8(37)
Recent thermodynamic and experimental studies have suggested that volatile organic compounds (e.g., methane, formate, and acetate) can be produced and stabilized in subduction zones, potentially playing an important role in the deep carbon cycle. How

Magnetic characterization of ghost rocks from the Sterkfontein cave (South Africa): are iron oxides linked to biological activity?
Autor: Laurent Bruxelles, Aude Isambert, Maud Watkinson, Richard Maire, Céline Pisapia, Emmanuelle Gérard, Bénédicte Ménez
The Sterkfontein caves system in the Cradle of Humankind (South Africa) is a karstic environment resulting from a ghost-rock karstification process that developed in the Malmani dolomite formation presenting interlayered more resistant chert layers (
