Dr Karen V Smit 


My research interests are in the sample-based investigation of geological processes in the deep Earth.


Over the last 14 years, my research has included radiogenic and stable isotopic studies that use mantle xenoliths and diamonds to investigate the petrology and chemistry of the deep Earth; tectonic processes that affect the mantle and result in the growth of continents; and using the stable isotopic composition of diamonds as the ultimate tracer of the deep carbon and nitrogen cycles.
