New data for intrusive meta-igneous rocks from the Southwest terrane of the Sør Rondane Mountains confirm the view that this is a juvenile oceanic arc terrane, with the main phase of subduction-related magmatic activity around 995–975 Ma. Younger magmatism (960–925 Ma) is more varied: a high Sr/Y (‘...
