Oxidative weathering of organic carbon in sedimentary rocks is a major source of CO2 to the atmosphere over geological timescales, but the size of this emission pathway in Earth's past has not been directly quantified due to a lack of available proxy...

Vanadium isotope fractionation during plutonic differentiation and implications for the isotopic composition of the upper continental crust (2024)
Journal Article
Stow, M. A., Prytulak, J., Humphreys, M. C., Hammond, S. J., & Nowell, G. M. (2024). Vanadium isotope fractionation during plutonic differentiation and implications for the isotopic composition of the upper continental crust.

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...

Rhenium elemental and isotopic variations at magmatic temperatures (2024)
Journal Article
Wang, W., Dickson, A., Stow, M., Dellinger, M., Burton, K., Savage, P., …Prytulak, J. (2024). Rhenium elemental and isotopic variations at magmatic temperatures. Geochemical perspectives letters, 28, 48-53. https://doi.org/10.7185/geochemlet.2402

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.
