| contents | The varved sediment of Lake Suigetsu is one of the most precisely age-controlled sedimentary archives in the world, with annual layers (varves) counted by dual methods as well as > 800 radiocarbon dates. The dataset has been used as a central component of the IntCal20 radiocarbon calibration model. In addition, the sedimentation rate around 40 kyr BP is quite high (90‒100 cm/kyr). From the core SG14 of the sediment, we have obtained a high (21-yr) resolution paleomagnetic record from 45 to 35 IntCal20 kyr BP. The record includes the Laschamp Excursion and a new post-Laschamp (Suigetsu) excursion. The mid-ages and varve-counted durations are 42,050 ± 120 IntCal20 yr BP and 790 yr for the Laschamp Excursion, and 38,830 ± 140 IntCal20 yr BP and 550 yr for the post-Laschamp (Suigetsu) excursion, respectively. These excursions coincide with the double minima of paleointensity and maxima of Δ14C. |
