Abstract
More than 50 varve-thickness diagrams, which were established from glacial varved clays in south-eastern Sweden were correlated with each other to for m an 800-year long floating varve chronology. AMS C-14 measurements on terr estrial macrofossils from the varved clays enabled synchronization of the r ecord with other high-resolution archives. The synchronization indicates th at the chronology spans between c. 13 150 and c. 12 350 calendar years BP a nd covers the later part of the Allerod and the early part of the Younger D ryas. Calibrated radiocarbon dates, which were obtained on varved clays sou th of the floating chronology. indicate that the ice recession in south-eas tern Sweden may have started during late Boiling. Our results indicate a lo nger time-span in varve years for the deglaciation than has been previously estimated.
