摘要

Earth is a differentiated planet. Its primordial building blocks of iron-rich metal, oxides, silicate minerals, and volatile elements and compounds have been transformed over geological time into the modern-day structure of core, mantle, crust, ocean and atmosphere. Chemical and physical processes such as mantle convection, tectonic-plate recycling and magma generation through partial melting should have scrambled, if not obliterated, any coherent geochemical signature of the primordial material. Even if a vestige of such material remained, it seems unlikely that it would be found in any samples from Earth's surface or the shallow subsurface that are available to geologists.
