PhD in Mantle and Isotope Geochemistry – Gardar Alkaline Province Geological Survey of Denmark and Greenland in Denmark

PhD opportunity in mantle and isotope geochemistry at the Geological Survey of Denmark and Greenland (GEUS) in Copenhagen, Denmark, in collaboration with the Natural History Museum of Denmark, the University of Copenhagen, and Aarhus University.

The project is part of REE-GAP and investigates mantle metasomatism, volatile processes, and the origin of REE and HFSE mineralisation in the Gardar Alkaline Province of South Greenland. Research will use an integrated geochemical and isotopic approach, combining trace element geochemistry, radiogenic isotopes (Sr–Nd–Pb), and advanced stable isotope tracers.

Key research themes include characterising mantle source compositions using primitive melts, dyke swarms, and mantle xenoliths; tracing volatile sources and slab-derived components; and evaluating the role of volatile-rich metasomatism in alkaline magmatism. The project is based on existing sample collections, 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, with daily workplace at GEUS. Salary and employment terms follow the relevant trade union agreement.

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 methods is an advantage; fluent English.

Application deadline: 25 May 2026 (Danish time). Required documents: CV, short motivation/qualification cover letter, diploma, MSc and BSc transcripts, and if the MSc is not yet completed, a signed and institution-confirmed pre-approval of the MSc thesis.
