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:

  1. Rates of magma generation and emplacement
  2. Magma sources
  3. Mineralisation processes
  4. Magma degassing histories
  5. Magma redox conditions

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