PhD Position in Deformation & Microstructures of Eclogites
100%, Zurich, fixed-term
The Structural Geology and Tectonics Group led by Professor Whitney Behr welcomes applications for a 4-year Ph.D. position on subduction interface rheology, deformation, and microstructures.
Eclogite is a dense, high-pressure metamorphic rock that can influence the strength of subduction interfaces and the deep lower crust, affecting plate coupling, slab pull, crustal foundering, and how stresses accumulate and release at depth. Field observations indicate that, under certain conditions, eclogite deforms by diffusion creep-a weak, grain-size-sensitive mechanism that can accelerate deformation, enhance fluid transport, and help localize strain. However, the strength of eclogite in this regime has never been quantified experimentally. This project will deliver the first high-pressure/high-temperature calibration of eclogite diffusion-creep behavior and directly validate it against natural samples from Norway’s Western Gneiss Region using field and microstructural observations. The PhD student will focus on shear/deformation experiments, detailed microstructural analyses (EBSD/EDS, microprobe, FTIR, micro-CT), and the integration of experimental and natural datasets, including participation in field campaigns in the Western Gneiss Region.
Job description
- Perform shear/deformation experiments under diffusion-creep conditions; assist with high-P/T runs
- Conduct microstructural and petrological analyses of experimental and natural samples (EBSD/EDS, microprobe, FTIR, micro-CT)
- Participate in fieldwork and sampling in Norway; link natural structures to laboratory results
- Present findings at group meetings, international conferences, and in peer-reviewed journals
Profile
- MSc in Earth Sciences/Geology or a related field
- Background in structural geology, petrology, or rock mechanics; enthusiasm for experimental and microstructural work
- Solid English skills; collaborative, organized, and comfortable with field campaigns
- Curiosity, positivity, and care with delicate equipment
