flumus

Flumus is a fictional mineral introduced in speculative fiction and as an example in discussions of mineral nomenclature. It does not correspond to a known natural substance and is used here to illustrate how a mineral article is typically structured in encyclopedic writing.

In the fictional accounts, flumus is said to form in high-temperature hydrothermal veins within basaltic crust, usually alongside manganese oxides and pyroxenes. It is described as a translucent to opaque mineral with a layered microstructure, with color varying from pale blue-green to deep violet depending on trace elements such as copper or vanadium. Reported hardness is modest, around 3 to 4 on the Mohs scale, and the density is in the range of 2.5 to 3.0 g/cm3. The material is often depicted as exhibiting luminescence under ultraviolet light and as having a relatively low reactivity at room temperature.

Synthesis and extraction in fictional contexts involve standard mining methods to access vein deposits, followed by ore concentration through flotation and impurity removal via acid leaching. Its imagined luminescent properties have led to mentions of potential pigment and ceramic applications within narratives, as well as theoretical considerations for energy-related materials in some speculative discussions.

The article notes that flumus is a product of creative discourse rather than a verified mineral. See also: fictional minerals, speculative mineralogy, mineral terminology.
