The analysis of emerging stable isotopic systems in clastic sedimentary rocks is increasingly used to determine the average composition of the upper continental crust through geological time. Any temporal variations can then be linked to global-scale...

Recent analytical advances in the measurement of rhenium (Re) isotope ratios allow its potential as a palaeoredox and chemical weathering proxy to be explored. However, a successful isotopic proxy must be grounded by an understanding of its compositi... Read More about Rhenium elemental and isotopic variations at magmatic temperatures.

A significant portion of the continental crust is composed of plutonic igneous rocks. However, little is known
about the geochemical behaviour of N between the different minerals during magmatic differentiation. To
provide new constraints for the... Read More about Equilibrium partitioning and isotopic fractionation of nitrogen between biotite, plagioclase, and K-feldspar during magmatic differentiation.

A primary magmatic source of nitrogen to Earth’s crust (2023)
Journal Article

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 melts (that... Read More about A primary magmatic source of nitrogen to Earth’s crust.

Slab to back-arc to arc: Fluid and melt pathways through the mantle wedge beneath the Lesser Antilles (2023)
Journal Article
Hicks, S. P., Bie, L., Rychert, C. A., Harmon, N., Goes, S., Rietbrock, A., …Kendall, J. (2023). Slab to back-arc to arc: Fluid and melt pathways through the mantle wedge beneath the Lesser Antilles. Science Advances, 9(5), https://doi.org/10.1126/sciadv.add2143

Volatiles expelled from subducted plates promote melting of the overlying warm mantle, feeding arc volcanism. However, debates continue over the factors controlling melt generation and transport, and how these determine the placement of volcanoes. To...

Following the Indian-Asian continental collision, the Tibetan Plateau experienced continuous magmatism from south to north, most of which is characterized by high potassium (K) content and negative niobium‑tantalum‑titanium (Nb-Ta-Ti) anomalies. We p... Read More about Identifying Tethys oceanic fingerprint in post-collisional potassium-rich lavas in Tibet using thallium isotopes.
