Journal Article
Perrin, A., Goes, S., Prytulak, J., Davies, D., Wilson, C., & Kramer, S. (2016). Reconciling mantle wedge thermal structure with arc lava thermobarometric determinations in oceanic subduction zones. Geochemistry, Geophysics, Geosystems, 17(10), 4105-4127. https://doi.org/10.1002/2016gc006527

Subduction zone mantle wedge temperatures impact plate interaction, melt generation, and chemical recycling. However, it has been challenging to reconcile geophysical and geochemical constraints on wedge thermal structure. Here we chemically determin...

Sediment transport from the subducted slab to the mantle wedge is an important process in understanding the chemical and physical conditions of arc magma generation. The Aleutian arc offers an excellent opportunity to study sediment transport process... Read More about Tracking along-arc sediment inputs to the Aleutian arc using thallium isotopes.

The stable isotope composition of vanadium, nickel, and molybdenum in crude oils (2015)
Journal Article
Ventura, G. T., Gall, L., Siebert, C., Prytulak, J., Szatmari, P., Huerlimann, M., & Halliday, A. N. (2015). The stable isotope composition of vanadium, nickel, and molybdenum in crude oils. Applied Geochemistry, 59, 104-117. https://doi.org/10.1016/j.apgeochem.2015.04.009

Crude oils often have high concentrations of transition metals including vanadium (V), nickel (Ni), iron (Fe), and to a lesser extent molybdenum (Mo). Determining the conditions under which these metals enter into crude oil is of interest for the und...
