More than 50 varve‐thickness diagrams, which were established from glacial varved clays in south‐eastern Sweden were correlated with each other to form an 800‐year long floating varve chronology. AMS |214|0C measurements on terrestrial macrofossils from the varved clays enabled synchronization of the record with other high‐resolution archives. The synchronization indicates that the chronology spans between c. 13 150 and c. 12 350 calendar years BP and covers the later part of the Allerørd and the early part of the Younger Dryas. Calibrated radiocarbon dates, which were obtained on varved clays south of the floating chronology, indicate that the ice recession in south‐eastern Sweden may have started during late Bølling. Our results indicate a longer time‐span in varve years for the deglaciation than has been previously estimated
