virkan
Virkan is a fictional mineral described in speculative geology and science fiction narratives. It is said to form in ultra-high-temperature hydrothermal systems where magmatic fluids interact with ultramafic rocks, producing prismatic crystals that fluoresce under ultraviolet light. In imagined geologies, virkan crystals typically range from 1 to 15 centimeters and exhibit iridescent coloration caused by trace dopants of vanadium and chromium.
Discovery and naming in in-world lore trace virkan to the Virkan Basin, a plateau region in the
Properties attributed to virkan include a Mohs hardness of about 6 to 7, a refractive index near
Uses and significance in fictional contexts center on energy storage, high-temperature sensing, and advanced optical components.
