Freya George is a second year PhD student in the Department of Earth Sciences at Carleton University in Ottawa, Canada. Her research attempts to further our understanding of some of the fundamental metamorphic mineral-forming processes. This work combines high-resolution X-ray µ-computed tomography with quantification of the compositional variation contained within mineral populations and numerical simulation of garnet growth. The EGU 2016 poster presented results pertaining to a metapelitic garnet population from the Sikkim Himalaya, and showed that the garnet progressively nucleated and grew very rapidly, with approximate maintenance of an equilibrated state to peak metamorphic conditions.
