Research interests

My current research interests are focussed on the use of accessory minerals, principally zircon and apatite, to reveal information on crustal processes.

1. Zircon as an indicator of low and medium grade metamorphic processes.

2. Apatite thermochronology and the thermal structure of the shallow crust.

3. Grain boundaries and the movement of fluids through the crust. The morphology of apatite mineral surfaces as a guide to palaeoporosity and deformation in crustal rocks.

4. Chemical zoning in accessory minerals as a monitor of crystallisation history.

5. The initial phases of orogenic evolution and links between surface processes and tectonics.

. The kinetics of metamorphic reactions and the importance of chemical zoning in rock-forming minerals such as micas, in controlling equilibrium.

The use of thermochronology to monitor denudation histories in high elevation tectonic regions.

The geological evolution of the British Caledonides.

.
