Research interests
My research focuses on chemical and isotopic heterogeneity in the mantle. In particular, I am interested in determining the magnitude and spatial distribution of such heterogeneities and determining the implications of these anomalous compositions in various tectonic settings. I use a variety of isotope systems to investigate these problems and collaborate with a number of research groups in Europe and the US. My current research interests are relatively diverse but have a common peridotite theme:
The Pb paradox and Os isotopic gap: the role of mantle sulphides as refractory domains. With Steve Shirey (Carnegie Institution, Washington) Jessica Warren (Stanford University), Janne Koorneeff (Vrije University)
The effects of melt depletion, metasomatism, and supergene weathering on S-Se-Te and PGE in pyroxenite xenoliths from Kilbourne Hole, NM. With Stephan König (University of Tübingen) and Lukáš Ackerman (Czech Academy of Research, Prague)
Controls on the high PGE content of primary spinel. With Camilla Watson, Lewis Whitely, Richard Walshaw (University of Leeds), Zhuyin Chu (State Key Laboratory for Lithosphere Evolution, Chinese Academy of Science), Samantha Hammond (Open University).
Nd isotope heterogeneity at the grain scale in the mantle. With Ethan Baxter (Boston College) Matt Jackson (University of California, Santa Barbara), Jessica Warren (University of Delaware)
The effects of melt depletion, metasomatism and supergene weathering on 3He/4He and trace element abundances in peridotite-hosted olivine. With David Graham (Oregon State University), Samantha Hammond (The Open University) and Cees-Jan de Hoog (University of Edinburgh)
The nature and extent of stable isotope (Ni, Mo, V, Cr) fractionation in mantle peridotites. With Yu- Hsuan Liang (Academia Sinica, Taiwan), Julie Prytulak (Durham University), Naomi Saunders (University of Oxford), Matthew Jerram (University of Oxford), Alex Halliday (Columbia University)
Trace element systematics of variably altered peridotite-hosted base metal sulphides. With Jessica Warren (University of Delaware) Munir Humayun (Florida State University), Richard Walshaw (University of Leeds)
What do pallasite meteorites tell us about processes deep in the interior of differentiated planet(essimal)s? With Maeve Quinlan-Murphy (University of Leeds), Andrew Walker (University of Leeds), Chris Davies (University of Leeds), Thomas Mueller (University of Leeds, Jon Mound (University of Leeds).
Unravelling Early Earth evolution: the onset of plate tectonics at Isua, SE Greenland. With Thomas Mueller (University of Leeds), Sandra Piazolo (University of Leeds), Alex Webb (University of Hong Long)
Improving the precision of measurements of Nd isotopes in foraminifera for paleo-oceanographic applications. With Frances Proctor (University of Leeds), Tracy Aze (University of Leeds)
Chemical and isotopic tracers of the transition between oceanic and continental sub-continental lithospheric mantle. With Elena Curtis (University of Leeds), Dan Morgan (University of Leeds), Matt Pankhurst (INVOLCAN)
The origins of Scottish orogenic gold. With Shane Webb (University of Leeds), Taija Torvela (University of Leeds), Rob Chapman (University of Leeds)
