Kristie Dorfler

I received my PhD at VT in 2014. My research interests focus on high- to ultra-high-temperature (> 1000 °C) metamorphic reactions that occur in mid–to-deep crustal contact settings. This involves understanding various properties of UHT metamorphism and its implications for crust–mantle relationships including (I) partial melting and methods of melt extraction in contact aureoles or in xenoliths (II) country rock–magma interaction, specifically with mafic–to-ultramafic magmas, and melt mixing that occurs between these two materials (III) constraints on mineral reactions and textural development (or arrested development) in dry, UHT environments. My primary methods involves analytical techniques with an electron microprobe, SEM or optical microscope in addition to computer modeling to thoroughly understand these systems on a micron-scale. Field observations, in conjunction with laboratory work, lead me to understand the seamless connection between micro- and macro-scale metamorphic processes.


I left Virginia Tech in August 2014 for a Visiting Assistant Professor position in the Geology Department at Oberlin College where I will focus on teaching undergraduate courses including both Mineralogy and Petrology, and providing some assistance to undergraduate research projects under the primary advising of Zeb Page.
