Fully funded PhD opportunity in mantle and isotope geochemistry focused on the Gardar Alkaline Province in South Greenland. The project investigates mantle metasomatism, volatile processes, and the origin of critical metal enrichment, with particular attention to rare earth element (REE) and high field strength element (HFSE) mineralisation. The position is hosted at the Geological Survey of Denmark and Greenland (GEUS) and is carried out in collaboration with the Natural History Museum of Denmark , the University of Copenhagen , and Aarhus University . The PhD student will be enrolled at the PhD School of Science, University of Copenhagen . Research topics include trace element geochemistry, radiogenic isotopes (Sr–Nd–Pb), advanced stable isotope tracers, mantle source characterization, primitive melts, dyke swarms, and mantle xenoliths. The project uses existing sample collections, and no fieldwork is planned. Eligibility highlights: a master’s degree in geoscience, geochemistry, petrology, or a related field; strong analytical and quantitative skills; interest in mantle processes and/or isotope geochemistry; experience with geochemical or isotopic analytical methods is an advantage; fluent English is required. Funding: fully funded 3-year PhD employment under relevant trade union agreement, with salary and terms according to GEUS/Ministry rules. The working week is 37 hours. Application window: apply online by 25 May 2026 (Danish time). Required documents include CV, cover letter, MSc and BSc diploma/transcripts, and if the MSc is not yet completed, a signed pre-approval of the MSc thesis.

GEUS (Geological Survey of Denmark and Greenland) is offering a fully funded 3-year PhD position in mantle and isotope geochemistry focused on the Gardar Alkaline Province in South Greenland. The project, part of the Geocenter Denmark-funded REE-GAP research programme, investigates mantle metasomatism , volatile processes , and the origin of REE and HFSE mineralisation. The research uses existing sample collections from GEUS and the Natural History Museum of Denmark, with no fieldwork planned. The PhD will apply an integrated geochemical approach, including trace element geochemistry , radiogenic isotopes (e.g. Sr–Nd–Pb), and stable isotope tracers to study slab-derived fluids, sedimentary contributions, and mantle source modification. The work is based at GEUS and includes collaboration with the University of Copenhagen , Natural History Museum of Denmark , and Aarhus University . Eligibility highlights: a master’s degree in geoscience, geochemistry, petrology, or a related field; strong analytical and quantitative skills; interest in mantle processes and isotope geochemistry; experience with geochemical or isotopic methods is an advantage; fluent English required. The student will be enrolled in the PhD School of Science, University of Copenhagen , and the programme includes courses and a research stay abroad. Funding: the position is fully funded and salaried under the relevant trade union agreement for a 3-year appointment. Application deadline: 25 May 2026 (Danish time). Apply via the online portal and include CV, cover letter, diploma, transcripts, and MSc thesis pre-approval if applicable.

PhD opportunity in mantle geochemistry , isotope geochemistry , petrology , and critical metal enrichment at the Geological Survey of Denmark and Greenland (GEUS) , in collaboration with the Natural History Museum of Denmark , the University of Copenhagen , and Aarhus University . The project, Mantle Metasomatism and REE Fertility in the Gardar Alkaline Province (REE-GAP) , investigates mantle metasomatism and volatile processes in the Gardar Alkaline Province of South Greenland . The research focuses on how the lithospheric mantle becomes enriched in elements and volatiles that lead to rare earth element (REE) and high field strength element (HFSE) mineralisation. The work will use an integrated geochemical and isotopic approach, combining trace element geochemistry with radiogenic and advanced stable isotope tracers. Key research themes include: characterising mantle source compositions using primitive melts, dyke swarms, and mantle xenoliths; applying stable isotope systems to trace volatile sources and slab-derived components; integrating radiogenic isotope systems such as Sr–Nd–Pb ; and evaluating the role of volatile-rich metasomatism in alkaline magmatism. The project is based on existing sample collections curated at GEUS and SNM, and no fieldwork is planned . This is a fully funded 3-year PhD position . The student will be enrolled in the PhD School of Science, University of Copenhagen , and will follow the PhD programme including courses and a research stay abroad. The daily workplace will be at GEUS in Copenhagen. Eligibility highlights: a master’s degree in geoscience, geochemistry, petrology, or a related field; strong analytical and quantitative skills; interest in mantle processes and/or isotope geochemistry; experience with geochemical or isotopic analytical methods is an advantage; and fluent English communication. If the MSc is not yet completed, a signed pre-approval of the MSc thesis is required. Application deadline: 2026-05-25 . Apply online and submit a CV, short cover letter, diploma, and transcripts (MSc and BSc). If applicable, include the MSc thesis pre-approval document.
