Dual Nd isotopic archives in fossil teeth reveal bottom-current control of rare-earth element enrichment in deep-sea sediments

The global emergence of deep-sea sediments enriched in rare-earth elements and yttrium (REY) after the Late Eocene cooling coincides spatiotemporally with Antarctic bottom water (AABW) expansion, yet the underlying mechanism remains unresolved. Here, we present in situ elemental...
