Kviitungite

Kviitungite is a fictional mineral species used in speculative mineralogy and science fiction world-building. It is not recognized by real-world mineral databases or the International Mineralogical Association, and no physical specimens exist in scientific catalogs. The name is invented for narrative purposes and has no formal etymology or type locality in reality.

In in-universe descriptions, kviitungite is imagined as a copper- and iron-rich oxide-sulfide that forms as irregular to prismatic microcrystals within hydrothermal veins. Its composition is variable, typically described as containing copper and iron with sulfur and oxygen in a sulfide-oxide matrix; trace elements such as nickel and cobalt may be present.

Physical properties attributed in fiction include a metallic to submetallic luster, a dark gray to black color, and an opaque appearance. Mohs hardness is described as moderate, and density as relatively high. It is said to occur with other copper-bearing minerals such as chalcopyrite and bornite in altered basaltic rocks.

In fictional geology, kviitungite is valued for its alleged electrical or magnetic properties and is sometimes depicted as an ore of interest for advanced alloys, though these claims have no basis in real science.

Discovery and usage: The mineral name appears in world-building texts, lore, and speculative papers, not in peer‑reviewed mineral descriptions. See also: fictional minerals, mineral nomenclature in fiction.
