Decompressed eclogites in the Sveconorwegian Province, SW Sweden, have been dated using U-Pb geochronology. Zircons are common as inclusions in garnet and kyanite, and other minerals in the decompressed eclogites. Titanite inclusions are found exclusively in the core of garnets. The mineral inclusions and the chemical zoning of the garnets suggest inital growth under prograde amphibolite facies conditions followed by eclogite facies metamorphism and subsequent decompression through the high-pressure granulite and upper amphibolite facies. The zircon and titanite thus formed prior to the eclogite stage of the P-T path. The age of the eclogite forming event was determined by ion probe dating of zircon inclusions in garnets. The obtained age of 972+/-14 Ma is the maximum age of the eclogitisation. The age of the titanite inclusions in garnet is 945+/-4 Ma. This age is similar to other U-Pb ages of titanite in the region which suggest that the titanite has been isotopically reset and that the age reflects cooling.The mode of occurrence, textural relationships and the chemical homogeneity suggest that the zircons formed from Zr released from magmatitic Fe-Ti oxides and possibly amphiboles during breakdown of magmatic minerals at the onset of the Sveconorwegian metamorphism.Spot analyses of complex zircons from a granitic dyke in the eclogite yielded an age of 1403+/-15 Ma for magmatic cores and an age of 963+/-22 Ma for metamorphic rims. The older age is a minimum age of the eclogite protolith and correspond to the age of a generation of granites in the region. The rim age is within error identical to the age of eclogite metamorphism. The eclogite metamorphism in SW Sweden is younger than its Grenvillian counterparts in Scotland, Canada and USA.
