Light elements in the Earth's outer core: A critical review

JP Poirier - Physics of the earth and planetary interiors, 1994 - Elsevier
There is little doubt that densities for the Earth's outer core, inferred from seismology, require
that it is constituted of an alloy of liquid iron and light elements. However, the nature of the …
