WebJan 16, 2024 · Experiments have demonstrated the persistence of microbiological structures such as iron oxide organominerals up to 250 °C and 140 MPa (Picard et al., 2015a), and the preservation of lipids and polysaccharides within Fe-encrusted microbial cells at the same PT conditions (Picard et al., 2015b). WebOrganominerals are the mineralic products of organomineralization. They should be distinguished from minerals precipitated through inorganic processes, among which some may contain OM entombed or complexed during crystal growth, from organic minerals such as graphite and from biominerals produced by living organisms.
