Levyosien

Levyosien is a fictional mineral described in speculative geology and science fiction. It is presented as a layered silicate mineral that forms under high-temperature hydrothermal conditions in basaltic crusts and is used in fictional materials science to explore advanced energy and photonic properties.

The name levyosien combines the constructed root levyo- with the common mineral suffix -sien; in the fictional literature, it honors a pioneer geologist and follows a convention of science-fiction mineral nomenclature.

Levyosien is described as forming tabular crystals with a layered structure. Typical composition is dominated by silicon-oxygen framework with aluminum and magnesium in the lattice, with trace transition metals such as vanadium or iron substituting in. Colors range pale blue to emerald green; Mohs hardness around 6–7; it exhibits luminescence under UV light and high anisotropy in thermal conductivity.

In the fictional setting, levyosien forms in ultramafic to basaltic rocks within hydrothermal veins on the planet Zyrion. It is believed to crystallize from silica-rich fluids under pressures of 1–5 gigapascals and temperatures of 700–900 degrees Celsius, often alongside other silicate minerals.

In speculative contexts, levyosien is proposed as a candidate material for high-density energy storage, ion conduction along layered planes, and photonic devices. It serves as a theoretical model for studying pressure-induced phase transitions and anisotropic transport, though there is no empirical confirmation in real-world geology.
