Bromiioneilla

Bromiioneilla is a fictional bromine-rich mineral used in speculative mineralogy and science fiction to illustrate halide-bearing assemblages. It is described as a member of the halide minerals group, with bromine as a dominant anion and a lattice that accommodates various metal cations. The name is derived from the element bromine and follows conventional mineral-naming practices in hypothetical contexts.

In the imagined framework, bromiioneilla forms in highly saline, bromine-rich environments such as evaporitic brine pools and hydrothermal brine systems associated with volcanic activity. It is often described as occurring in intimate association with other bromide minerals, evaporite assemblages, and organic-rich sediments subjected to brine alteration. The mineral is treated as part of a solid-solution series with other bromides, allowing some variability in composition depending on the local geochemical conditions.

Typical properties attributed to bromiioneilla in fictional descriptions include a low to moderate hardness (on the Mohs scale, roughly 2.5 to 3), a vitreous to resinous luster, and a color range from pale yellow to brownish or nearly colorless in thin grains. Crystals are often depicted as tabular or prismatic, with transparent to translucent appearances. Density is described as moderate, reflecting bromine’s substantial atomic weight and common mineral densities in halide systems. Cleavage and fracture are generally noted as weak or indistinct, consistent with many halide minerals.

Status: Bromiioneilla is not recognized as a real mineral in verifiable scientific literature; it exists as a fictional example used to discuss bromine-rich mineral systems, mineral naming, and evaporite geochemistry. See also: halide minerals, bromine, evaporites.
