elunditel

Elunditel is a fictional mineral described in speculative geology and fantasy literature. It does not correspond to any recognized mineral in real-world science, but is used in fictional narratives to explore mineral properties, discovery, and value in a believable geological setting.

In fictional descriptions, elunditel is a rare blue‑green silicate mineral noted for a faint luminescence under ultraviolet light. Reported physical properties vary by source, but common portrayals assign a Mohs hardness around 5.5–6.5, a density near 3.9 g/cm3, and a refractive index around 1.70–1.75. Its appearance is typically described as having a metallic to vitreous luster with a distinct color banding under mixed lighting.

Occurence and formation are usually tied to hydrothermal activity in ultramafic or related igneous rocks, with elunditel appearing in veins alongside minerals such as magnetite, chromite, and amphibole. The mineral is often presented as forming at high temperatures with slow cooling, though other stories place its genesis in younger tectonic settings. The exact chemical composition remains debated within these fictional worlds, with hypotheses ranging from a complex aluminosilicate to an iron- and magnesium-bearing silicate with trace rare-earth elements.

Etymology and naming in the fiction trace elunditel to a mythical Elund region and a conventional mineral suffix. The term is popular in narrative contexts for exploring themes of discovery, rarity, and the speculative boundaries between science and imagination. In real science, elunditel is treated as a fictional construct used for worldbuilding and storytelling.
