Decreasing extents of Archean serpentinization contributed to the rise of an oxidized atmosphere
Nature Communications, 2021 Throughout the Archean, H2 generation via low-temperature ultramafic serpentinization likely helped prevent atmospheric O2 accumulation and continued until the abundance of ultramafic rocks diminished setting the stage for the Great Oxidation Event.
