Age models of core 1 based on sedimentological evidences and 4 AMS ¹⁴C datings. Dots represent mean values of 1σ-ranges whereas error bars indicate 2σ-ranges. All dates were calibrated with CALIB v 5.0.1. The age model considering bulk sedimentation-rates (including event layers LT B2 and B3) is indicated by dashed lines, whereas the age model based on background sedimentation-rates (event layers LT B2 and B3 removed) is drawn with solid lines. For the purpose of establishing a concise event chronology, the age model on the basis of background sedimentation was used in this study
