Hi all, Sorry if you get this several times through different channels. I'm very happy to advertise a 36-month postdoc position hosted at the Department of Earth Sciences, Oxford, supported by a NERC Pushing the Frontiers grant "NITRO-MET: Reactive Nitrogen Supply Driven by Orogenic Metamorphism". This project has collaborators and project partners at the universities of Hull, St Andrews, Edinburgh, and Halle (Germany). This project seeks to quantify the behaviour of nitrogen and its isotopes during orogenesis, specifically focusing on the role of mica and feldspar in pelitic sediments undergoing regional metamorphism and partial melting. This will be achieved through field sampling, laboratory analyses, and petrological modelling of metamorphic phase equilibria in orogenic environments. Nitrogen retention and degassing rates during burial, exhumation, and later erosion will be determined using time-dependent thermal-tectonic models of collisional orogenesis. As the flux of bio-essential elements from continental landmasses to the oceans plays a major role in the development of Earth-surface habitability, these data will be used to test broader hypotheses about how plate tectonic and surface processes associated with the supercontinent cycle are related to marine productivity and greenhouse-icehouse periodicity throughout geological time. We are looking for candidates with knowledge/experience of field mapping and sampling in metamorphic terranes, chemical and petrological analysis of metamorphic rocks, petrological modelling of phase equilibria, and stable isotope geochemistry. This work will involve fieldwork in Canada and visits to the Edinburgh Ion Microprobe Facility to conduct SIMS analyses. The deadline is midday on 8th May, 2026.
