Lithiumilla

Lithiumilla is a fictional lithium-bearing mineral species devised for geology-focused fiction and speculative discussions about lithium-rich pegmatites. It is not recognized in real-world mineralogy.

In the fictional descriptions, Lithiumilla is characterized as a lithium-bearing silicate with variable substitutions by magnesium, iron, and aluminum. A representative composition that appears in some narratives is Li(Mg,Fe)Si2O6 with possible end-members such as LiAlSi2O6. The mineral is said to form in late-stage crystallization of granitic magmas and to occur as prismatic crystals with a vitreous luster. Color is described as ranging from pale green to blue, though these hues vary by depiction.

Occurrence and associations in the imagined setting place Lithiumilla in lithium-rich pegmatites and related granitic rocks, often alongside real minerals such as spodumene, lepidolite, and quartz. The stories use Lithiumilla to illustrate lithium resources and the challenges of extracting high-purity lithium from complex mineral suites.

Discovery, naming, and classification are editorial elements of the fiction. The name derives from its lithium content, with the diminutive suffix -illa, but Lithiumilla has no basis in official mineral nomenclature and no physical samples exist in reality. Consequently, it is not listed by the International Mineralogical Association.

Uses and significance in the fictional context typically center on hypothetical lithium mining or battery-related plots, serving as a narrative device rather than a real-grade mineral resource.
