Based on the analysis of gravitational and magnetic anomalies eastern part East European Platform, it is concluded that inhomogeneities caused by serpentinization processes are present in Earth’s crust. This conclusion confirmed conducting geological geophysical studies reference objects with serpentinite outcrops.

Abstract The ca. 3.5 Ga Bon Accord Ni deposit was located in the Barberton Greenstone Belt of Kaapvaal Craton, South Africa, and contained a unique assemblage Ni-rich minerals including trevorite (NiFe2O4). It initially interpreted as metamorphosed extraterrestrial body, recently ruled out by Cr isotope data, subsequently fragment Archean Earth’s core. More recent suggestions have highlighted s...

Abstract Mantle serpentinization influences the rheology of altered peridotites and global fluxes energy volatiles, generation seafloor sub-seafloor chemolithotrophic life, carbon cycle. As a by-product serpentinization, molecular hydrogen (H2) is generated, which supports chemosynthetic communities, this mechanism may have driven origin life on early Earth. At continent-ocean transition zones ...

Abstract Serpentinization of peridotites in Earth’s mantle is associated with the generation hydrogen and low molecular weight organics that could support subsurface life. Studies microbial metabolisms peridotite-hosted environments have focused primarily on methanogenesis, yet DNA sequences, isotopic composition sulfides thermodynamic calculations suggest there potential for sulfate reduction ...
