DOI: 10.1016/j.chemgeo.2021.120192
Abstract: Abstract The distribution of nitrogen between the different terrestrial reservoirs (core-mantle-atmosphere) and how this may have changed since the earliest planetary stages is uncertain. In particular, the primordial degassing processes of the magma ocean and… read more here.
