Theoretically, when a planet or large body differentiates enough to form a core, certain elements including osmium, iridium, ruthenium, platinum, palladium, and rhenium-known as highly siderophile elements-are segregated into the core.
Its impact origin was confirmed with the discovery of shatter cones (Dietz 1960), shocked quartz (Carlton and others 1998; Koeberl and others 1998), and coesite (Cohen and others 1961) and is supported by the enrichment of siderophile elements at the center of the structure (Carlton and others 1998; Koeberland others 1998).
Third, the chalcophile (Cu, Pb, Zn, Cd, Mo, As, Ag, Bi) and siderophile elements (Ni, Co) form a large group occupying the middle of the diagram.
Some siderophile and chalcophile elements such as Au and the Platinum Group elements (PGE's) are more strongly partitioned into immiscible sulfide liquid than Ni.
