The NE Fennoscandian Shield comprises numerous ultramafic platinum-group element (PGE) bearing intrusions. This paper involves the use of precise isotope analyses with U‐Pb on zircon and baddeleyite. It refines the chronology of these disparate intrusions and indicates a protracted 130 Ma magmatic evolution with major events at 2.53, 2.50, 2.45, and 2.40 Ga. This degree of precision on these events refines our understanding of the formation of Precambrian crust in NE Europe and specifically in the Kola region. The results will also help mining companies in exploration for barren vs mineralised intrusions; importantly many of these metals are critical in modern electronics and catalytic converters.
The results also indicate at a major period of enriched mantle magmatism at this period and help refine our understanding of mantle convection in the late Precambrian.
