* Emplacement and development of large igneous provinces.
* Origin and nature of mantle plumes.
* Partial melting processes in the mantle and crystallisation / mixing processes in the crust.
* U-series disequilibrium studies of mantle dynamics & melting, magma chamber processes, and geochronology.
* Subduction-related magmatism and element fluxes at subduction zones.
* Environmental geology: e.g. pollution tracers, weathering processes, geoarchaeology.
* Geochemical monitors of past global environmental changes.
* Melt inclusions in crystals as a monitor of melt compositional diversity and pre-eruptive volatile contents.
