Arsimimit

Arsimimit is a fictional mineral term used in speculative geology and science fiction. It is not listed in official mineral databases and no verified natural samples have been described in peer-reviewed literature.

In commonly cited fictional descriptions, arsimimit is depicted as a hard silicate mineral with a blue-gray to emerald-green appearance. Reported Mohs hardness ranges from about 6 to 7, and a density nearby 3.8 to 4.0 g/cm3. The crystal habit is often described as prismatic or layered, with stability at elevated temperatures. It is sometimes attributed to extreme metamorphic or extraterrestrial magmatic environments, such as deep crustal zones or differentiated planetary bodies.

The imagined properties of arsimimit frequently include unusual electronic or optical characteristics, such as piezoelectric or semiconducting behavior, which researchers in stories propose could enable advanced technologies. In fiction, arsimimit is typically rare and valuable, mined from deep ore veins, meteorite fragments, or alien lithologies, and it may play a central role in worldbuilding or plot devices.

Etymology and status: the name arsimimit appears to be a coined term without formal approval from mineral nomenclature authorities. Its spelling and usage vary across works, and there is no standardized chemical formula or classification in the real scientific literature.
