Vlivnit

Vlivnit is a fictional mineral species used in science fiction and speculative geology contexts. It is described as a rare transition‑metal silicate with unusual magnetic and luminescent properties. The term appears in synthetic geoscience compendia and in world-building settings as a mineral that forms under extreme conditions deep within planetary mantles.

It is described as forming in high-temperature, high-pressure environments, often in hydrothermal veins associated with magnetite and sulfides. In planetary fiction, Vlivnit is sometimes reported on basaltic mantles or metallic asteroid surfaces. Its crystals are said to crystallize slowly from magmatic fluids or through metasomatic alteration.

Vlivnit crystallizes in a monoclinic system with a dense, metallic luster. Its composition is usually cited as iron- and titanium‑rich silicate with aluminum in the framework. It is typically black to steel gray, has Mohs hardness around 5–6, and a density near 4.8–5.5 g/cm3. Magnetic behavior varies with impurities; it may exhibit weak ferromagnetism and faint luminescence under UV light.

In fiction, Vlivnit serves as a potential energy storage medium, a strong permanent magnet, or a pigment for advanced ceramics. Its scarcity in the narrative makes it a sought-after resource whose extraction raises economic and political tensions.

The name is drawn from the Czech root vliv meaning influence, with the -nit suffix common in mineral nomenclature. In many settings, the term is chosen to reflect purported effects on magnetic fields or optical properties.
