Career Research Highlights
Colin has applied new and established geochemical techniques in innovative ways to understand the origins of magmatism and its relationship to tectonics. He has developed particular expertise in SE Asia and the western Pacific where he has studied subduction initiation, lithosphere erosion, mantle melting, crustal growth and recycling of subducted crust and sediment. Colin has also conducted pioneering work in the analysis and use of light elements to investigate magmatic processes, in recognition of which he received the Geological Society’s Wollaston Fund in 2007. He was responsible for setting up a stable isotope laboratory at Durham with more than £300,000 of SRIF2 funding and has obtained more than £500,000 of other grant income since 2001.
