oksüdeeruda

Oksüdeeruda is a fictional mineral described in speculative geology and used in world-building narratives. It is defined as a hydrated oxide phase that forms under hydrothermal conditions in oxidizing environments. In the imagined geosphere, oksüdeeruda emerges when hot, mineral-rich fluids interact with preexisting rocks, allowing water to be incorporated into the crystal lattice and altering its structure. The mineral is noted for its distinctive coloration and refractive properties.

The name oksüdeeruda combines a root related to oxide with a fictional suffix, reflecting its oxide-rich composition and enigmatic, almost hidden origin. In published lore, the term is attributed to researchers who first described the mineral in the Ardent Depths sequence.

In the fictional scheme, oksüdeeruda occurs as transparent to translucent crystals with a pale-green to blue-green hue. It typically displays a vitreous to resinous luster and a Mohs hardness around 6 to 7. It shows distinct cleavage along two perpendicular directions and has a high refractive index, contributing to notable optical brightness under incident light. UV exposure elicits faint luminescence.

Oksüdeeruda is reported from deep-sea hydrothermal belts and high-temperature metamorphic zones in the setting’s crust. It is commonly found with quartz, chlorite, and sulfide minerals. In-world significance includes potential use as a decorative stone and as a component in fictional energy storage or electro-optical devices, due to its insulating properties and luminescence.

Research on oksüdeeruda appears in in-universe geology monographs and field reports. These sources discuss formation pathways, stability under varying pressure and temperature, and the mineral’s theoretical applications, while noting that much about its origin remains debated.
