Funded Activity Summary
From plume source to hotspot: quantifying mixing in mantle plumes and its implications for the nature of deep-mantle heterogeneity. Mantle plumes are buoyant upwellings that bring hot material from Earth's deep-mantle to the surface, forming volcanic hotspots, like Hawaii. Although extensively studied, the geochemical variations recorded in hotspot lavas have, so far, proved difficult to understand, particularly how they relate to their heterogeneous deep-mantle source. This project aims to use state-of-the-art geodynamical models to determine how deep-mantle heterogeneities are transported into a plume and how such heterogeneities are mixed during plume ascent. This will facilitate the linking, for the first time, of geochemical variations at volcanic hotspots to the deep-mantle's thermo-chemical structure, under an Earth-like, fluid-dynamical framework.Funded Activity Details
