The eastern boundary of Sveconorwegian reworking in the Baltic Shield,defined by 40Ar/39Ar geochronology across the southernmost Sveconorwegian Province
New 40Ar/39Ar dates of hornblende, biotite and muscovite from 13 localities along a 130 km transect in southern Sweden provide insight into the cooling and exhumation history during Sveconorwegian orogeny, from 970 to 880 Ma. The Eastern Segment represents Baltican continental crust underthrust below the western Sveconorwegian terranes at 990–970 Ma. The western part of the Eastern Segment consistNew 40Ar/39Ar dates of hornblende, biotite and muscovite from 13 localities along a 130 km transect in southern Sweden provide insight into the cooling and exhumation history during Sveconorwegian orogeny, from 970 to 880 Ma.
