Strongly peraluminous granites provide independent evidence for an increase in biomass burial across the Precambrian–Phanerozoic boundary Open
Strongly peraluminous granites (SPGs) are generated by the partial melting of sedimentary rocks and can thus provide a novel archive to reveal secular trends in Earth’s environmental history that integrate siliciclastic sedimentary litholo…

A primary magmatic source of nitrogen to Earth’s crust Open
The igneous portion of Earth’s continental crust represents a long-term sink of terrestrial nitrogen, but the origin of the nitrogen in this reservoir remains ambiguous. Possible sources include magmatic differentiation of mantle-derived m…

Boocock et al_Behaviour of N during differentiation - Hekla Open
Raw and compiled N data, major/trace element data and other isotopic data for the Hekla volcanic system. Data supports nitrogen not behaving as a volatile element and not degassing during magmatic differentiation.

Reconstructing Nitrogen Sources to Earth’s Earliest Biosphere at 3.7 Ga Open
Earth’s sedimentary record has preserved evidence of life in rocks of low metamorphic grade back to about 3.2–3.5 billion years ago (Ga). These lines of evidence include information about specific biological metabolisms, permitting the rec…

Nitrogen Mass Fraction and Stable Isotope Ratios for Fourteen Geological Reference Materials: Evaluating the Applicability of Elemental Analyser Versus Sealed Tube Combustion Methods Open
Thirteen commercially available silicate reference materials (RM) and one in‐house reference material, eleven of which have no previously published values, were analysed for nitrogen mass fraction and isotopic ratios with an Elemental Anal…
