Geochemistry and Mineral Resources

The group's research is focused on using the geochemistry, mineralogy and petrology of rocks to understand the origin and evolution of the Earth’s crust, mantle, atmosphere, biosphere and hydrosphere, how and why these reservoirs have changed, and which geological and tectonic processes have shaped our planet over geological time.

In addition, the interface to material science is also of interest and a part of research is directed towards the mineral-related materials used in industry.

The research is heavily focused on geochemical and mineralogical analytical work, in laboratories based at IGN (Microprobe, XRD, TIMS, ICPMS) and also carried out in collaboration with laboratories and facilities hosted by external international partners. The group also contributes a broad range of petrological, mineralogical and geochemical courses in the Department, ranging from introductory level to advanced Master’s levels courses.
