Geology and mineralogy – research and personnel

Geology and mineralogy – research and personnel


At Åbo Akademi University, geological research is primarily conducted within the areas of bedrock geology and environmental geochemistry. Bedrock geology priorities research on the Fennoscandian Shield: its formation, evolution and resources. We specialise in magmatic petrology, structural geology, isotope geology and mineralogy. Environmental geochemistry research focuses on how anthropogenic and climate-related geochemical processes in land areas affect watercourses. We identify risk factors and develop strategies and methods for reducing the environmental loading of watercourses and coastal areas of the Baltic Sea.

Our water courses are strongly dependant on climate change, geology and land-use. In envioronmental geochemistry we study the interaction between hydrogeochemical processes in the catchment and recipient water courses. Photo: Peter Österholm.
