Kozmosit

Kozmosit is a fictional mineral species used in geology education and mineral nomenclature demonstrations. The name is derived from kosmos, the Greek word for universe, reflecting a speculative cosmic origin.

Composition and structure: Described as a silicate-oxide mineral containing aluminum, silicon and alkali metals with trace elements. The simplified empirical formula is variable in educational examples. It is stated to crystallize in the monoclinic crystal system and to form prismatic crystals that are transparent to translucent.

Physical properties: Kozmosit is described as having a vitreous to sub-vitreous luster, a white to pale gray streak, and a Mohs hardness around 6. Specific gravity is typically cited around 3.2–3.6.

Occurrence and environment: In fictional depictions, kozmosit forms in high-temperature metamorphic rocks and in simulated extraterrestrial contexts, often in ultramafic assemblages. It is commonly described as occurring with minerals such as peridot, garnet and pyroxene.

Discovery and naming: The term kozmosit is used in teaching materials to illustrate how minerals are named and classified. It is not recognized as a formally named mineral species by the International Mineralogical Association.

Uses and significance: Its primary use is educational—to demonstrate mineral classification, nomenclature and the interpretation of physical properties. It may appear in software simulations and classroom exercises.
