Career Research Highlights
Nowell is a specialist in multi-collector plasma ionisation and thermal ionisation mass spectrometry. Much of his career has specialised in Lu-Hf isotope measurements applied to mantle samples, combining this approach with Re-Os geochemistry to provide powerful constraints on the origins of potassic magmas and pyroxenite lithologies in the mantle. Recently he has been developing methods for ultra-low (pg and below) Pt analyses in DNA extracted from anti-cancer drug therapy patients (with the Northern Institute for Cancer Research) and laser ablation sulphur isotope ratio measurements in DGT gels (with Lancaster Environmental Sciences School).
Research Interests
● Development and application of the Lu-Hf isotope system. ● Development of laser ablation and solution based analytical methodolgies using Multi Collector ICP Mass Spectrometry (MC-ICP-MS) ● Methodologies for accurate and precise correction of atomic and polyatomic interferences during MC-ICP-MS isotope ratio measurements. ● Geochemistry of kimberlites and lamproites. ● Isotopic evolution of the mantle & crust
Teaching areas
