Research Interest
Zircon as an indicator of low and medium grade metamorphic processes. Garnet zoning and the role of diffusion processes in controlling metamorphic reractions. Grain boundaries and the movement of fluids through the crust. The morphology of mineral surfaces as a guide to reaction history, palaeoporosity and deformation in crustal rocks. Chemical zoning in accessory minerals as a monitor of crystallisation history. The initial phases of orogenic evolution and links between surface processes and tectonics.
