Summary: | The identification of tephra within varved deposits of a former ice-dammed lake that existed in Scotland during the Younger Dryas provides an opportunity to calibrate 10Be production rates using previously published 10Be concentrations from the lake shoreline and independently derived ages for the tephra’s derived from the Greenland Ice Core records. The best-estimate ages of the tephras yield indistinguishable 10Be production rate values for spallation with an average value of 4.26 ± 0.21 atoms g-1 a-1 using the ‘Lm’ scaling scheme. These values are in best agreement with the most proximal reference 10Be production rate from Norway. |
