Rhenium isotope variations in Icelandic groundwaters and hydrothermal systems (2024)
Journal Article
Wang, W., Dickson, A. J., Dellinger, M., Burton, K. W., Clark, D. E., Eggertsson, G. H., Einarsdóttir, Í. E., Ingimarsson, H., Mesfin, K. G., Hilton, R. G., & Prytulak, J. (2024). Rhenium isotope variations in Icelandic groundwaters and hydrothermal systems. Earth and Planetary Science Letters, 647, Article 119046. https://doi.org/10.1016/j.epsl.2024.119046

The isotopic composition of rhenium (Re) has potential for use as a proxy to infer changes in seafloor redox and/or global oxidative weathering intensity. Despite an emerging dataset on this nascent isotope system in Earth's surficial environments, v... Read More about Rhenium isotope variations in Icelandic groundwaters and hydrothermal systems.

Rhenium Isotopes Record Oxidative Weathering Intensity in Sedimentary Rocks (2024)
Journal Article
Dickson, A. J., Hilton, R. G., Prytulak, J., Minisini, D., Eldrett, J. S., Dellinger, M., Stow, M., & Wang, W. (2024). Rhenium Isotopes Record Oxidative Weathering Intensity in Sedimentary Rocks. Geochemistry, Geophysics, Geosystems, 25(10), Article e2024GC011795. https://doi.org/10.1029/2024gc011795

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. Earth and Planetary Science Letters, 643, Article 118825. https://doi.org/10.1016/j.epsl.2024.118825

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.
