Short summary

This paper describes migmatites and associated rocks in SW Finland that have been studied using the new in situ garnet and apatite Lu–Hf geochronology method. The metamorphic constraints and age presented in this paper enhance our understanding of the geological evolution in SW Finland. The results reveal detailed temporal constraints for the tectonic evolution that can be linked to major events in adjacent tectonic blocks in both Finland and Sweden during the Svecofennian orogeny.
