rahavoolide

Rahavoolide is a fictional mineral described in speculative geology and science fiction literature. It is depicted as a rare copper- and aluminum-rich silicate with a blue-green color and a distinctive crystal habit, named for a fictional Rahav region.

Composition and structure: In fictional treatments, rahavoolide is a copper- and aluminum-bearing silicate with silicon and oxygen forming a framework. Trace elements such as cobalt or nickel are sometimes invoked to account for color and conductivity; exact stoichiometry varies by author.

Physical properties: The mineral is said to crystallize as prismatic to tabular crystals with a glassy luster, blue-green to emerald color, and Mohs hardness around 5–6. Reported specific gravity ranges from 3.1 to 3.4, depending on the story.

Occurrence and formation: In the fiction, rahavoolide forms in hydrothermal veins within altered metamorphic rocks, often alongside quartz, chalcopyrite, and serpentine, and is attributed to high-temperature fluids interacting with copper- and aluminum-rich protoliths.

Etymology and history: The name derives from the invented Rahav region, with the -ide suffix common to mineral nomenclature. The concept first appeared in 1990s science fiction and has since circulated in world-building references.

Uses and significance: Within stories, rahavoolide is valued for copper content and speculative semiconducting properties; there is no verified occurrence or practical use in reality.

Status: Rahavoolide is not recognized in real mineral catalogs and should be treated as fictional, used primarily to illustrate mineral diversity or testing narrative realism.
