tarusid

Tarusid is a fictional mineral used in science fiction and world-building contexts. In the stories and simulations where it appears, tarusid is described as a rare aluminosilicate-oxide mineral with a metallic luster and iridescent sheen, forming slender tabular crystals. It is commonly attributed chemical traits such as trace elements of titanium and vanadium, a Mohs hardness around 6–7, a density near 5.0 g/cm3, and a refractive index around 1.75. Colors range from dark gray to blue-black, with vivid rainbow-like iridescence under direct light.

Formation and occurrence: In fiction, tarusid is said to form under extreme high-temperature and high-pressure conditions, such as subduction-zone metamorphism, impact-melt pockets, or synthetic reactors in advanced civilizations. Natural occurrence is described as exceedingly rare or localized to fictional regions or meteorite inclusions; there is no verified geological site for tarusid in the real world.

Uses and significance: Tarusid is often depicted as a strategic material for decorative stone, high-performance ceramics, or exotic electronics, sometimes associated with piezoelectric or pyroelectric properties in speculative sources. Because tarusid is a fictional construct, there are no established synthesis protocols or peer-reviewed studies in real mineralogy.

Etymology and reception: The name tarusid is typically linked to fictional regions or star systems named Tarus, and it has been adopted by several authors and game designers to anchor world-building details. The concept serves as a narrative device to explore material science in speculative settings.
