Abstract
An important constraint on the reliability of cosmogenic nuclide exposure dating is the rigorous determination of production rates. We present a new dataset for 10Be production rate calibration from Mount Billingen, southern Sweden, the site of the final drainage of the Baltic Ice Lake, an event dated to 11,620 ± 100 cal yr BP. Five samples of flood-scoured bedrock surfaces (58.5°N, 13.7°E, 105–120 m a.s.l.) unambiguously connected to the drainage event yield a reference 10Be production rate of 4.19 ± 0.20 atoms g−1 yr−1 for the CRONUS-Earth online calculator Lm scaling and 4.02 ± 0.18 atoms g−1 yr−1 for the nuclide specific LSDn scaling. We also recalibrate the reference 10Be production rates for four sites in Norway and combine three of these with the Billingen results to derive a tightly clustered Scandinavian reference 10Be production rate of 4.13 ± 0.11 atoms g−1 yr−1 for the CRONUS Lm scaling and 3.95 ± 0.10 atoms g−1 yr−1 for the LSDn scaling scheme.
