PhD student position in Metamorphic Petrology and Geochemistry: Petrochronology of fluid-rock interactions in subduction zones

The computational petrology and geochemistry group hosted at the Institute of Geological Sciences, University of Bern is seeking a PhD student to contribute to the development of new analytical techniques and numerical tools for the investigation of fluid-rock interaction processes and element mobility in subduction zones.

The open position is fully funded for 36-48 months, within the framework of the Horizon 2020 ERC StG project PROMOTING . The PhD candidate is expected to develop a strong multidisciplinary profile including both analytical petrology and numerical modeling skills.

There are two main objectives of this PhD project. (1) The development of a technique for the exploration of element repartition in 3D by integrating computerized tomography (CT) scan and electron probe micro-analyzer (EPMA). (2) The development of a general framework to model multi-rock systems including phase equilibria and isotope fractionation models. These new tools will be combined with in-situ geochronology and applied to different rock types in high- pressure and ultra-high pressure terranes throughout the Western Alps. The aim of this work is to deepen our understanding on the magnitude and tempo of fluid-rock interaction processes in subduction zones.
