Nanoscale mineral-microbial interactions, associations, and biosignatures in gypsum stromatolites

Project description

Looking for signs of microbial-mineral cooperation and life remnants in gypsum deposits

Stromatolites are laminated rocky structures made by tiny, sun-loving microorganisms. They comprise the oldest undisputed evidence of fossil life on Earth, dating back more than 3.5 billion years. Lake Bakili in Ethiopia hosts atypical stromatolites made of gypsum whose challenging accessibility has left them largely unexplored. With the support of the Marie Skłodowska-Curie Actions programme, the interdisciplinary NanoBioS project will study the microbiology and mineralogy of these newly discovered stromatolites. Scientists are looking for evidence of mineral-microbial interactions and potential remnants of living organisms in the stromatolites to better understand mineral-microbial synergy and shed light on how to distinguish inorganic biomorphs from real fossils in gypsiferous deposits.
