... Many of these planetesimals had metallic iron cores and during growth of the Earth this metal re-equilibrated with the Earth's silicate mantle, extracting siderophile (`iron-loving') elements into the Earth's iron-rich core. ... Chemical signature of core formation Growth of the Earth from planetary embryos and planetesimals resulted in the substantial partitioning of siderophile elements into the metallic core, leaving lithophile elements behind in the silicate mantle. ... REE, rare-earth elements....
