auringolta

Auringolta is a hypothetical mineral described in speculative geology and in science fiction literature. It is characterized by a golden-bronze color and a distinct iridescent sheen that intensifies under direct solar illumination. The mineral is said to crystallize in subidiomorphic prismatic crystals and to occur in metamorphic and impact-related rock environments. Its described composition centers on a silicate-oxide phase with iron, aluminum, and trace light elements such as titanium and vanadium, yielding a high refractive index and a bright appearance.

Discovery and name in fiction: The term emerged in early 22nd-century discussions of solar-irradiated minerals within arid planetary regolith simulations and in speculative narratives. In many stories, the earliest described specimen is reported from a fictional Solara Ridge, with researchers from a Lunar Institute reference, circa 2147.

Formation in hypothetical settings: In these scenarios, auringolta forms when high-temperature fluids interact with silica-rich rocks under intense solar radiation, promoting incorporation of light elements that enhance optical brightness. Models often describe rapid crystallization in narrow veins, with continued solar exposure causing color and luster to intensify.

Physical properties in fictional accounts: In the imagined mineral, Mohs hardness is placed around 6–7; density is high and variable; luster is strongly adamantine. Some surveys note pleochroism from golden to bronze hues and, in certain editions, photoluminescent response under ultraviolet light.

Uses and significance: Within speculative worlds, auringolta is proposed as an ornamental material and a potential photonic component for solar-energy devices. Its imagined scarcity limits practical use, making it mostly a narrative or symbolic element in fiction.
