根据瑞典东南部的冰川纹层粘土建立的50多个纹层厚度图相互关联，形成了长达800年的浮动纹层编年史。AMS| 214|对来自纹泥的陆地宏体化石的测量使记录与其他高分辨率档案同步。同步指示时序表跨越c。13150和C。12 350日历年BP和覆盖Allerørd的后期和新仙女木的早期部分。在浮动年代学以南的纹粘土上获得的校准放射性碳年代表明，瑞典东南部的冰衰退可能在博林晚期开始。我们的研究结果表明，冰川消退的时间跨度比以前估计的要长，
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
