PhD candidate who’s research focusses on understanding volcanic and magmatic processes at mid-ocean ridges through the application of in-situ analytical techniques.
Broadly, my research interests include volcanic and magmatic processes and crustal evolution. More specifically I am interested in using crystal-scale studies to understand the processes occurring in magma plumbing systems.
To date my PhD research has examined the physical nature of, and processes occurring within, the Gakkel Ridge magma plumbing system. This has involved using an integrated dataset of mineral and glass geochemistry, melt inclusion geochemistry and crystallisation pressures, basalt crystal content and bathymetric and geophysical datasets.
Crystal-scale records of the Gakkel Ridge plumbing system
Whilst Mid-ocean ridges (MOR), such as the East Pacific Rise and Mid-Atlantic Ridge have been studied extensively, the Gakkel Ridge, the slowest spreading MOR in the World’s oceans has received comparatively little attention. Using the crystal cargo of basalts dredged from along the Gakkel Ridge in 2001, this project aims to investigate how the physical nature of (e.g., melt vs. crystal content and crystallisation pressures), and processes occurring within (e.g., magma mixing, mush disaggregation), the magma plumbing system change along axis and what controls any variations.
Ultimately, by constraining the physiochemical conditions of the Gakkel Ridge magma plumbing system we can better understand crustal accretion at ultraslow spreading ridges.
The PhD project is supervised by Dr Johan lissenberg (Cardiff) and Prof. Katharine Cashman (Bristol).
