Depth, IntCal20 age, declination, inclination, VGP latitude, VGP longitude, magnetic susceptibility, and relative paleointensity of core SG14 from Lake Suigetsu, Central Japan

DOI

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.
