My research focuses on investigating the chemical stratigraphy of robust accessory minerals to understand the generation and evolution of silicic magmas within the Earth’s crust. These minerals often document multiple stages of magma evolution which coupled with their inventory of key elements enables better constraints on a wide variety of igneous processes including:

Rates of magma generation and emplacement

Magma sources

Mineralisation processes

Magma degassing histories

Magma redox conditions

These processes have direct applications for the evolution of Earth’s continental crust mineralisation and exploration for geothermal energy.
