Oleksid

Oleksid is a fictional mineral that appears in speculative geology and science fiction contexts. It is typically described as a layered silicate mineral with distinctive optical and electrical properties that make it useful in theoretical discussions about mineral physics.

Etymology and naming: The name oleksid is a constructed term, often attributed to authors who create minerals for world-building. It is not sanctioned by any mineralogical authority.

Physical properties (in fiction): In most depictions oleksid has a hardness near 6–7 on the Mohs scale, a color range from pale teal to deep blue-green, and a vitreous to pearly luster. The crystal structure is usually described as containing alternating silicate layers with planarly coordinated metals, yielding anisotropic electrical conduction in some models.

Occurrence and formation: In fictional narratives, oleksid forms in high-pressure, high-temperature environments such as subduction-zone rocks or deep planetary crust. It is sometimes said to crystallize from fluids enriched in lithium, vanadium, or rare earth elements, though these details vary by author.

Uses and cultural role: Within stories, oleksid crystals are sometimes described as gemstones or as theoretical semiconductors with unusual charge mobility. Because oleksid is a fictional material, there is no real-world synthesis or safety data.
