This study presents the first U/Pb SHRIMP II dates on zircons from metasomatic sillimanitehypersthene rocks within the Porya Guba nappe of the Lapland Granulite Belt. The results yielded a Paleoproterozoic Svecofennian age (1913–1914 Ma) of the HT/HP metasomatism in shear zones during collision-related metamorphic events in the Lapland Granulite Belt.
