Volcanic emissions and the early Earth atmosphere

Abstract:

Despite uncertainties in our understanding of early Earth volcanism and atmospheric composition, thermodynamic modelling is able to offer estimates of the global production of reactive trace species (NO, OH, SO₃, Cl, Br, and I) from early Earth volcanism, and thereby to shed light on processes which may have been different in Earth's early atmosphere. Model results show that thermal decomposition of magmatic H₂O, CO₂ and SO₂ in high-T mixtures of magmatic and atmospheric gases (at T > 1400...
