Integrated Petrological and Fe-Zn Isotopic Modelling of Plutonic Differentiation (2021)
Journal Article
Stow, M. A., Prytulak, J., Humphreys, M. C., & Nowell, G. M. (2022). Integrated Petrological and Fe-Zn Isotopic Modelling of Plutonic Differentiation. Geochimica et Cosmochimica Acta, 320, 366-391. https://doi.org/10.1016/j.gca.2021.12.018

The upper continental crust is formed from chemically diverse granitic plutons. Active debate surrounds the range of physical conditions (P-T-X-fO2) and differentiation processes which occur in mush bodies that solidify to form plutons. Transition me...

Thallium Isotopic Compositions in Hawaiian Lavas: Evidence for Recycled Materials on the Kea Side of the Hawaiian Mantle Plume (2021)
Journal Article
Williamson, N. M., Weis, D., & Prytulak, J. (2021). Thallium Isotopic Compositions in Hawaiian Lavas: Evidence for Recycled Materials on the Kea Side of the Hawaiian Mantle Plume. Geochemistry, Geophysics, Geosystems, 22(9), Article e2021GC009765. https://doi.org/10.1029/2021gc009765

Hawaiian volcanoes record 6 Ma of potentially deep mantle chemistry and form two parallel volcanic chains that are geochemically unique, named Loa and Kea. Loa volcanoes erupt lavas with isotopically enriched compositions thought to reflect the prese...

Isotopic Compositions of Plagioclase From Plutonic Xenoliths Reveal Crustal Assimilation Below Martinique, Lesser Antilles Arc (2021)
Journal Article
Brown, J., Cooper, G., Nowell, G., Macpherson, C., Neill, I., & Prytulak, J. (2021). Isotopic Compositions of Plagioclase From Plutonic Xenoliths Reveal Crustal Assimilation Below Martinique, Lesser Antilles Arc. Frontiers in Earth Science, 9, Article 682583. https://doi.org/10.3389/feart.2021.682583

The chemical and isotopic compositions of volcanic arc lavas often show evidence for involvement of a sedimentary component during magma genesis. Determining where this sedimentary component is added to arc magmas is of vital importance for constrain...

Nature of the Cuvier Abyssal Plain crust, offshore NW Australia (2021)
Journal Article
Reeve, M. T., Magee, C., Bastow, I. D., McDermott, C., Jackson, C. A., Bell, R. E., & Prytulak, J. (2021). Nature of the Cuvier Abyssal Plain crust, offshore NW Australia. Journal of the Geological Society, 178(5), Article 172. https://doi.org/10.1144/jgs2020-172

Magnetic stripes have long been assumed to be indicative of oceanic crust. However, continental crust heavily intruded by magma can also record magnetic stripes. We re-evaluate the nature of the Cuvier Abyssal Plain (CAP), offshore NW Australia, whic... Read More about Nature of the Cuvier Abyssal Plain crust, offshore NW Australia.

Thallium elemental and isotopic systematics in ocean island lavas (2021)
Journal Article
Brett, E., Prytulak, J., Rehkämper, M., Hammond, S., Chauvel, C., Stracke, A., & Willbold, M. (2021). Thallium elemental and isotopic systematics in ocean island lavas. Geochimica et Cosmochimica Acta, 301, 187-210. https://doi.org/10.1016/j.gca.2021.02.035

The Earth’s mantle exhibits marked chemical heterogeneity. We provide an examination of thallium systematics in ocean island basalts (OIB): new high-precision trace element analyses, including Tl, and Tl isotopic compositions for 48 OIB spanning the...
