  • Deep reservoir chemistry in ocean island basalts

Currently in progress; details forthcoming! Main questions are surrounding the fundamental relationships (or lack thereof) between unusual isotopic signals in material likely sourced from the deep mantle.

Highly siderophile elements (HSEs) are sensitive to oceanic crust generation. The evolution of HSE abundance and Re-Os isotopic compositions in the uppermost mantle can be captured in ophiolites, or slivers of oceanic crust and mantle accreted onto continental crust. Through time, these “snapshots” of HSE behavior preserved in ophiolites can record major episodes of oceanic crustal extraction, and potentially other large mantle events.

Extensions of dissertation and postdoc work

The Lau Basin is the world’s youngest ocean basin and is proximal to a subduction zone and mantle plume. Here, I’m interested in determining the mantle sources participating in the generation of rare modern-day boninitic (or bonitoid) melts.

  • Geochemistry and geodynamics of the Rurutu mantle plume

This is a work-in-progress stemming from observations of long-term Rurutu plume behavior. Eruptive patterns and dynamics observed in the Rurutu hotspot track inform the plume’s dynamic structure in the upper mantle. These patterns also reveal some characteristics of the underlying mantle source that feeds the Rurutu plume.
