Olekranonile

Olekranonile is a fictional mineral described in speculative geology and science fiction to illustrate how new minerals might be named and characterized. It is not recognized by real-world mineral databases or peer‑reviewed literature.

The name combines olecranon, the anatomical term for the elbow, with the common mineral suffix -ile, following a pattern often used in mineral naming. In fictional contexts, the term is sometimes employed to explore naming conventions and to provide a plausible-sounding addition to a geologic lexicon.

In imagined accounts, olekranonile appears as a translucent mineral with a pale-green to teal color and a vitreous to subadamantine luster. It is typically described as possessing a moderate hardness—constrained within a speculative range of about 4 to 6 on the Mohs scale—with a refractive index that lends it noticeable brilliance under light. Its crystal habit is commonly described as prismatic or tabular, though such details vary by story or hypothetical dataset.

Formation and occurrence in fiction place olekranonile in hydrothermal settings associated with ultramafic or aluminum-silicate–rich rocks. It is often described as forming in veins or pockets where interacting fluids crystallize silicate minerals, and it may be imagined alongside minerals such as serpentine, olivine, or calcite.

Uses and significance in speculative contexts include decorative jewelry in storytelling, as a model to discuss mineral science, or as a hypothetical material with properties like stable performance under variable temperatures or luminescent behavior. Because olekranonile is not a real mineral, there are no empirical data or specimens to reference outside fictional narratives.
