sid·er·o·phile

 (sĭd′ər-ə-fīl′)
adj.
Relating to or being an element, such as gold, platinum, or iridium, that exhibits metallic bonding and has an affinity for iron. On earth, the siderophile elements are found in greatest abundance in the iron core.
n.
A siderophile element.

Highly Siderophile and Strongly Chalcophile Elements in High-Temperature Geochemistry and Cosmochemistry
Today, roughly 98 percent of Earth's highly siderophile elements are tucked away in its iron-rich core.
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).
