My research interests involve geochemistry, igneous petrology, and the development of analytical techniques. My particular interests include; (1) processes occurring at subduction zones, such as the dehydration of the subducting slab and the generation of arc magmas; (2) the recycling and redistribution of certain elements, particularly volatile and fluid-mobile elements, between different Earth reservoirs (e.g., mantle, crust and atmosphere).
After primarily working with stable isotope systems (e.g., O, S and B) I have recently switched focus to the noble gases (He, Ne, Ar, Kr and Xe), and their numerous isotopes, to investigate:
– The presence of recycled and primordial material in the source of MORB (mid ocean ridge basalt) and OIB (ocean island basalt)
– The fluxes of volatiles into (e.g., at subduction zones) and out of the mantle (e.g., at spreading centres)
– The geochemical evolution of mantle over the course of Earth’s history
This research forms part of the ERC funded NOBLE project and the NERC funded consortium project ‘Mantle Volatiles: Processes, Reservoirs and Fluxes’ (http://www.deepvolatiles.org/).
