Evidence for a late chondritic veneer in the Earths mantle from high-pressure partitioning of palladium and platinum

Holzheid, A; Sylvester, Paul; O'Neill, Hugh; Rubie, David; Palme, Herbert


The high-pressure solubility in silicate liquids of moderately siderophile 'iron-loving' elements (such as nickel and cobalt) has been used to suggest that, in the early Earth, an equilibrium between core-forming metals and the silicate mantle was established at the bottom of a magma ocean. But observed concentrations of the highly siderophile elements - such as the platinum-group elements platinum, palladium, rhenium, iridium, ruthenium and osmium - in the Earth's upper mantle can be explained...[Show more]
