The Central Scandinavian Dolerite Group - Protracted hotspot activity or back-arc magmatism? Constraints from U-Pb baddeleyite geochronology and Hf isotopic data
The Central Scandinavian Dolerite Group (CSDG) occurs in five separate complexes in central Sweden and SW Finland. U-Pb baddeleyite ages of dolerite dikes and sills fall into three age intervals: 1264-1271 (the Dalarna complex), 1256-1259 (the Vdsterbotten-Ulvo-Satakunta complexes) and similar to 1247 Ma (the Jamtland complex). Timing and spatial distribution of CSDG are unlike expressions of the
