Foorumites

Foorumites are a fictional category of minerals invoked in speculative geology and science-fiction settings. The name Foorumites combines the word forum with the common mineral suffix -ite, echoing a supposed origin in online communities and collaborative discussions. They are not recognized by official mineral databases or the International Mineralogical Association.

In the imagined taxonomy, Foorumites are hydrated aluminosilicates with layered structures akin to clays and micas. They are described as forming from silica- and alumina-rich fluids that interact with organic-rich sediments under low-temperature hydrothermal conditions. Crystals are typically tabular or prismatic, often translucent with pearly or vitreous luster.

Physical and optical properties: Mohs hardness 3–5; specific gravity around 2.5–3.0; refractive indices near 1.54–1.62. Colors range from pale green to blue or violet, depending on trace elements such as iron or titanium.

Occurrence and context: in fiction, Foorumites are reported from speculative volcanic rocks and altered basalts, as well as laboratory syntheses designed to explore naming conventions for minerals. They are commonly used to illustrate how new minerals are named and classified in the absence of real-world specimens.

Note: Foorumites are a fictional concept and not a real mineral.
