UHP metamorphism recorded by kyanite-bearing eclogite in the Seve Nappe Complex of northern Jämtland, Swedish Caledonides

► First evidence for UHP metamorphism in the Seve Nappe Complex of the Scandinavian Caledonides recorded by kyanite eclogite. ► Subduction of Baltica underneath an outboard terrane during the closure of the Iapetus Ocean in the Late Ordovician. ► UHP rocks emplaced from the hinterland collision zone during Scandian thrusting of the nappes.
