PhD Studentship: Magma emplacement and its evolution: deciphering between magmatic and tectonic processes

Primary Supervisor: Dr Zoja Vukmanovic

Scientific background: 

Layered intrusions represent natural laboratories frozen in time that provide us an opportunity to study how magma cools and differentiates, and how precious metals concentrate to form ore deposits. The ore deposits found in these intrusions are critical in achieving a carbon-zero future.  

However, these natural laboratories are often affected by tectonic events, overprinting the primary magmatic processes. Complicated geological histories result in modification of the mineral chemistry and rock microstructure. The study area, Bjerkreim-Sokndal (BKS) layered intrusion in Southern Norway, provides ample evidence of deformation, representing the best place to study both magmatic and tectonic processes. Apart from ilmenite (Ti) deposits, BKS has been recently identified as the most promising phosphate rock resource in Norway. The main aim of this project is to decipher between magmatic and post-emplacement microstructure to understand the formation and evolution of the intrusion. Additionally, how deformation has affected ore mineralisation hosted in BKS in terms of their microstructure and their geochemistry.  

Research methodology: 

The key objectives of this project are to 1) differentiate between magmatic and post-emplacement microstructure, and 2) identify the effect of deformation on the geochemistry of the main rock-forming minerals. The completion of both objectives will entail a combination of 1) fieldwork and petrography; 2) electron backscatter diffraction analyses (University of Cambridge); 3) Magnetic fabric analysis (University of St Andrews) and 4) mineral chemistry (Norwegian Geological Survey, Trondheim). The field trip will be carried out in year 1 (two weeks) in Bjerkreim Lobe of the BKS intrusion.  

Training:  

The individual will receive bespoke training in (1) digital and traditional mapping techniques (all supervisors); (2) microstructural analysis via electron backscatter diffraction analysis (EBSD), SEM, transmitted and reflected light microscopy (Vukmanovic); (3) rock magnetic techniques (McCarthy). Training will be largely one-to-one, working closely with supervisors at their modern laboratory facilities. 

Person specification:  

We are looking for applicants who have a BSc/MSc in Geology or related discipline and enthusiasm for field work and a strong motivation to succeed. We encourage applications from individuals who wish to mould this project around their research interests. 

Entry Requirements:

At least UK equivalence Bachelors (Honours) 2:1. English Language requirement (Faculty of Science equivalent: IELTS 6.5 overall, 6 in each category). 

Mode of Study:

Full-time

Start Date:

1 October 2026

Funding Information

ARIES studentships are subject to UKRI terms and conditions. Successful candidates who meet UKRI’s eligibility criteria will be awarded a fully-funded studentship, which covers fees, maintenance stipend (£20,780 p.a. for 2025/26) and a research training and support grant (RTSG). A limited number of studentships are available for international applicants, with the difference between 'home' and 'international' fees being waived by the registering university. Please note, however, that ARIES funding does not cover additional costs associated with relocation to, and living in, the UK, such as visa costs or the health surcharge.
