Soviteosan

Soviteosan is a fictional mineral concept that appears in speculative geology and educational exercises. Described as a complex silicate-oxide mineral with variable composition, it serves as a placeholder for discussing mineral classification, phase diagrams, and solid-solution during metamorphism. Because it is not a real mineral, reported formulas and properties vary by author and setting.

In the fictional framework, soviteosan is said to form under extreme metamorphic conditions, such as high-temperature and high-pressure environments in subduction zones or deep crustal rocks. Its structure is imagined as layered, with silicate tetrahedra connected to metal-oxide sheets, allowing a wide range of cation substitutions. This flexibility supports models of solid-solution and phase transitions.

Typical fictional descriptions assign rare-earth or transition metal elements to soviteosan, contributing to a variable color and refractive index in world-building contexts. The mineral is often depicted as rare and localized, occurring in ultramafic or granulitic assemblages in imaginary regions.

In practice, soviteosan is used as a teaching and storytelling tool to illustrate mineralogical concepts without risking misrepresentation of real minerals. It is not recognized by the International Mineralogical Association, and there are no lab measurements for soviteosan. Any data presented about it exist only within a fictional or speculative framework.
