My research focuses on the evolution of magmas in the sub-volcanic plumbing system. The formation of magma (composed of molten rock and solid particles termed crystals) is often complex and multi-stage. Although ultimately sourced from the mantle, the magmatic composition is often modified during assent through a combination of assimilation of foreign crustal material, mixing of magmas, crystallisation. These processes creates chemical heterogeneities within the magma, although subsequent magmatic evolution may erase these signatures.
My current research interests include:
- the relationship of basalt, andesite and rhyolitic magmas in arc settings and their petrogenesis.
- application of crystal forensics methods to decipher the history of magmas
- application of diffusion chronometry methods to investigate the timescales of magmatic processes prior to eruption
- linking crystal specific studies to monitoring signals at active volcanoes
- development of protocols of the analysis of geological materials at nanoscale spatial resolution
