numite

Numite is a fictional mineral that appears in science fiction and thought experiments about planetary geology; it is not an element or mineral recognized by scientific databases.

In depictions, numite is a dense, metallike mineral with a glassy luster; undisputed properties vary, but common traits include high density, electrical conductivity, and magnetic responsiveness; color ranges from dark gray to iridescent blue.

Formation and occurrence: In fiction, numite forms under high-pressure metamorphic conditions or in impact-generated fluids; some stories place it in metallic asteroidal deposits or in the mantles of icy moons.

Extraction and uses: Numite is typically described as valuable for energy storage, superconductivity, or as an exotic catalyst; processing involves high-temperature smelting or crystal growth under controlled atmospheres.

In culture and science fiction, numite functions as a plot device representing scarce, powerful materials.
