Continents in the Mantle Transition Zone? Sediment Recycling and the Geochemical Fertilization of the Deep Mantle

Continental crust is both created and destroyed at subduction zones. The project will investigate the geochemical enrichment of the mantle from "continent" subduction, its relationship to West Kimberley diamond deposits, shoshonite magmas and Au-Cu mineralization, and its implications for continent growth rates and mantle heterogeneity
