Dr Emma Humphreys-Williams
Chemical Laboratories Manager
Division: Imaging and Analysis Centre
Summary
I manage the chemical labs at the NHM, which specialise in the elemental analysis of natural and applicable synthetic samples. My research interests include; geochemistry of volcanic rocks and their relationship to melting processes; using intraplate volcanism to understand mantle melting processes and its evolution through time; volcanic carbonatites composition and occurrence; Mantle xenoliths as tracers of metasomatic processes; Alkaline rocks and carbonatites – a global view
