siderophile

Righter created a "bulk Moon" model composition similar to that of our planet to compare the concentrations of 14 volatile siderophile (metal-loving) elements from the Moon samples with his calculated values.

Iron became the dominant material in the core, intermixed with small amounts of several siderophile ("iron-loving") elements such as nickel and sulfur.

Highly Siderophile and Strongly Chalcophile Elements in High-Temperature Geochemistry and Cosmochemistry

Gold and platinum belong to a class of chemical elements known as the highly siderophile, or "iron-loving," elements.

It was noted that density variations are due to a larger or smaller amount of siderophile elements in the rock.

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.

Waterman, rather than making rock come alive theoretically in the way Russell does, chooses to reanimate it by reviving the few remnant rockbound organisms--endolithic lichens and siderophile bacteria.

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.

Platinum and gold are among eight occupants of the periodic table belonging to the category known as the highly siderophile elements.
