Kololicit

Kololicit is a hypothetical mineral used in mineralogy education to illustrate the characteristics of lithium-bearing silicates. It is described as a rare, naturally occurring mineral that forms in high-temperature metamorphic settings and during hydrothermal alteration of lithium-enriched pegmatites. The name Kololicit is said to derive from the fictional Kololia region, combining a geographic reference with the conventional mineral suffix -lit.

Chemically, kololicit is described as a lithium- and aluminum-rich aluminosilicate. Its composition is given as primarily lithium, aluminum, silicon, and oxygen, with minor sodium and fluorine as trace constituents. Crystallography is described as monoclinic with a hypothetical space group C2/m, and it is expected to show a vitreous luster. The mineral is described as pale green to colorless, translucent to transparent, with a Mohs hardness near 4.5 and a density around 3.0 g/cm3.

Occurrence and paragenesis: Kololicit is said to form in metamorphosed carbonate- or granitic rocks where hydrothermal fluids introduce lithium. It is often listed as associated with other lithium-bearing minerals such as spodumene, tourmaline, and quartz, suggesting formation through metasomatic and late-stage hydrothermal processes.

History and status: Kololicit has not been confirmed in peer-reviewed mineral literature and there are no authenticated specimens. It remains a constructed example used to illustrate mineral classification, naming conventions, and properties in educational contexts.
