From page 71...
... , rapid geochemical fluctuations in trace elements, stable isotopes, and Core levels describe a highly perturbed, unstable ocean-climate system. Significant positive excursions occur in 6~3C, 6~80, and Core values, and a final major trace element enrichment layer (advection event)
