Geochemistry and Igneous Petrology



Professor Jackson uses the isotopic and chemical composition of lavas erupted at plume-fed hotspot volcanoes to gain insight into the make-up of the Earth’s deep interior. In particular, he is interested in understanding the origins (recycling of subducted material, metasomatism, etc) and length scales (hemispheric to micron-scale) of heterogeneities in the mantle. He employs innovative in situ techniques to get at the composition of lavas, phenocrysts and the melt inclusions they host. Owing to the diversity of hotspots in the region, fieldwork in Polynesia plays an integral role in Professor Jackson’s research.
