Partitioning of palladium at high pressures and temperatures during core formation

K. Righter , M. Humayun & L. Danielson

An early equilibration of the Earth|[rsquo]|s mantle with the metals that later formed the core may explain the concentrations of iron-loving (siderophile) elements in the mantle. However, a subset of these elements, the highly siderophile elements including palladium, are present in greater concentrations than expected.
