Anomalous δ15N values in the Neoarchean associated with an abundant supply of hydrothermal ammonium
Abstract Unusually high δ15N values in the Neoarchean sedimentary record in the time period from 2.8 to 2.6 Ga, termed the Nitrogen Isotope Event (NIE), might be explained by aerobic N cycling prior to the Great Oxidation Event (GOE). Here we report strongly positive δ15N values up to +42.5 ‰ in ~2....
