olulistel

Olulistel is a fictional mineral commonly referenced in worldbuilding resources and speculative fiction. It is described as a rare framework silicate with a three-dimensional network of linked tetrahedra, yielding a distinctive combination of stability and fragility in imagined geology. The name is typically derived from a fictional locality or language element, with the suffix -stel following the common mineral naming convention.

In described properties, olulistel is colorless to pale blue, with a vitreous luster and a Mohs hardness around 6. It is said to crystallize in the monoclinic system and to form prismatic crystals that occur in hydrothermal veins. The chemical composition is treated as variable, commonly emphasized as aluminum- and silicon-rich, with trace iron and rare-earth elements; no single universal formula is used.

Geographically, worldbuilding texts place olulistel in continental crust settings, forming in high-temperature hydrothermal environments and often occurring with quartz, feldspar, and magnetite. It is portrayed as very rare, with restricted outcrops and small crystal sizes in most fictional depictions.

In fiction, olulistel is sometimes assigned special properties, such as luminescence under certain wavelengths or potential as a theoretical energy storage material due to intrinsic defect centers. Because olulistel is not recognized in real-world mineralogy, its characteristics vary across sources and are primarily used as a plotting device or worldbuilding element.
