Hematiteen

Hematiteen is a term used in speculative or fictional contexts to denote an iron oxide mineral closely related to hematite. It is not an officially recognized mineral by the International Mineralogical Association (IMA), and there is no formal chemical formula for hematiteen in mainstream mineral databases as of 2025.

The term combines hematite-related roots with the -een suffix common in mineral names, signaling a derivative or closely related phase of iron oxide.

Descriptions in literature describe hematiteen as a dense oxide with a metallic to earthy luster, typically dark red to black in color. Some speculative accounts assign a refractive index and magnetism akin to hematite, though these properties are not standardized.

Within fictional works, hematiteen is said to form through oxidation of iron-bearing minerals in high-temperature environments or as a lab-produced oxide via controlled oxidation of iron compounds. There are no verified natural occurrences in peer-reviewed mineral records.

In fiction, hematiteen is often depicted as a pigment, gemstone substitute, or potential iron ore for early metallurgical applications. In non-fiction contexts, the material remains unverified.

Because hematiteen is not an established mineral, readers should distinguish between factual mineral literature and fictional narratives in which the term appears.
