From Source to Surface: The dynamics of heterogeneous mantle plumes

Timothy David Jones
This thesis is a compilation of three papers investigating the relationship between mantle plume dynamics, Earth's thermo-chemical structure, and geochemical trends recorded by volcanic hotspots, using numerical simulations that are supported by geophysical and geochemical data sets. The results show that hotspot lavas reveal a wide range of dynamical plumes behaviour previously unrecognised, and that the systematic geochemical trends recorded in hotspot lavas have a complex relationship with deep mantle structure and composition.
