Large Pt anomaly in the Greenland ice core points to a cataclysm at the onset of Younger Dryas
Michail I. Petaev, Shichun Huang, Stein B. Jacobsen et al., 2013. Proceedings of the National Academy of Sciences 110(32), 12917–12920.
Trace-element analysis of GISP2 ice across the Bølling-Allerød/Younger Dryas boundary finds a large platinum anomaly without a matching iridium anomaly. The Pt/Ir ratio rules out mantle or chondritic sources; the authors suggest an Ir-poor iron meteorite, which they note is unlikely to produce an airburst or wide wildfires.
What it's used for here
The strongest single geochemical signal near the boundary, and its authors' own caveats.
