PhD Studentship: Magma emplacement and its evolution: deciphering between magmatic and tectonic processes University of East Anglia in United Kingdom

This PhD project at the University of East Anglia investigates the interplay between magmatic and tectonic processes in layered intrusions, focusing on the Bjerkreim-Sokndal (BKS) intrusion in Southern Norway. Layered intrusions serve as natural laboratories for understanding magma cooling, differentiation, and the concentration of precious metals into ore deposits, which are vital for a carbon-zero future. However, these geological formations are often modified by tectonic events, complicating the mineral chemistry and rock microstructure. The BKS intrusion is notable for its ilmenite (Ti) deposits and has recently been identified as Norway's most promising phosphate rock resource.

The project's main aim is to distinguish between magmatic and post-emplacement microstructures to elucidate the formation and evolution of the intrusion, and to assess how deformation has influenced ore mineralisation in terms of microstructure and geochemistry. Research objectives include differentiating magmatic from post-emplacement microstructures and identifying the effects of deformation on the geochemistry of key rock-forming minerals. Methodologies encompass fieldwork and petrography, electron backscatter diffraction analyses (in collaboration with the University of Cambridge), magnetic fabric analysis (with the University of St Andrews), and mineral chemistry studies (at the Norwegian Geological Survey, Trondheim). A two-week field trip to the Bjerkreim Lobe of the BKS intrusion is planned for the first year.

The successful candidate will receive tailored training in digital and traditional mapping techniques, microstructural analysis using EBSD, SEM, and microscopy, as well as rock magnetic techniques. Training will be delivered one-to-one in modern laboratory settings, working closely with supervisors. Applicants should hold a BSc or MSc in Geology or a related discipline, possess enthusiasm for fieldwork, and demonstrate strong motivation.

The project encourages candidates to shape the research according to their interests. Entry requirements include a UK equivalent Bachelors (Honours) 2:1 and an IELTS score of 6.5 overall (minimum 6 in each category). The position is full-time and starts on 1 October 2026.

Funding is provided through a fully-funded ARIES studentship, covering tuition fees, a maintenance stipend (£20,780 p.a. for 2025/26), and a research training and support grant. International applicants may have the difference between 'home' and 'international' fees waived, but relocation, visa, and health surcharge costs are not covered.
