A possible volcanic origin for the Greenland ice core Pt anomaly near the Bølling-Allerød/Younger Dryas boundary
Charlotte E. Green, James U. L. Baldini, Richard J. Brown et al., 2025. PLOS One 20(9), e0331811.
New platinum-group element data from the Laacher See tephra rule out that eruption as the source of the GISP2 Pt spike. Confirms on the GICC05 timescale a lag of several decades between the Pt spike and the NGRIP sulphur spike, places the Younger Dryas onset at 12,870 ± 30 yr BP, and proposes that the 14-year Pt spike records fractionated gas condensates from an Icelandic subglacial or submarine fissure eruption.
What it's used for here
