Geomorphic analysis of an active normal fault
Spectacular mountain front along the Aksehir normal fault.
Extension of the crust in southwest Turkey forms a series of normal faults whose slip rates and seismic hazard are not always well-known. I got involved in a project to study the activity of the Aksehir normal fault using a number of geomorphic indices that are easily obtained from digital elevation models.

MSci project: The thermal aureole of the Skaergaard intrusion
Where hot, molten rock intrudes into the Earth’s crust, it heats up the surrounding country rock and leaves a metamorphic aureole. Studying the thermal evolution of the aureole can yield clues on the initial temperature and the rate of cooling of the surrounding rock. During my Master’s thesis, I used the cathodoluminescence of Quartz to measure the maximum temperature attained by rocks in the aureole of the Skaergaard intrusion in eastern Greenland – with implications on the thermal evolution of the intruded magma body.
