Preoccupino

Preoccupino is a fictional mineral described in speculative science and worldbuilding contexts. It features in stories and games that explore advanced geology and energy technologies. The name is a coined term, often traced to a Latin root meaning "before" combined with a neologism intended to evoke anticipation.

Physical and chemical properties: Preoccupino is portrayed as a vitreous to sub-metallic mineral with iridescent internal zoning. It forms prismatic to tabular crystals and has a moderate hardness. In many depictions it is an aluminosilicate containing trace transition-metal inclusions; it is said to exhibit a high refractive index and faint photoluminescence under ultraviolet light. Thermal stability and resistance to basic acids are commonly cited features.

Occurrence, extraction, and processing: In fiction, preoccupino is found in deep crustal xenoliths and on certain asteroid surfaces. It is rare and expensive to mine, typically requiring high-pressure, high-temperature extraction and careful handling to prevent color loss.

Uses and significance: Preoccupino is valued as an energy storage material and as a catalyst component in speculative propulsion systems. It also appears as a luxury material or a speculative commodity in some settings. Some narratives treat it as geopolitically sensitive due to its scarcity and potential strategic applications.

Notes: Preoccupino does not exist in the real world and has no confirmed chemical or geological basis; it exists as a construct within fictional worlds and related meta-discourse.
