ofiarekosten

Ofiarekosten is a fictional mineral described here for illustrative purposes as part of a neutral, encyclopedia-style entry. In this hypothetical context it is classified as a rare silicate mineral with a potassium-sodium aluminum composition and a monoclinic crystal system. It is typically olive green to pale yellow, with a vitreous luster and a pale streak; it may show noticeable pleochroism under polarized light.

Occurrence and formation in the imagined setting place ofiarekosten in high-temperature alkaline pegmatites and metamict veins within granitic intrusions. In this scenario it is commonly associated with other alkali-rich minerals such as lepidolite, spodumene, and tourmaline, within rock bodies in the fictional Galan Ridge region. The mineral is thought to form during late-stage crystallization processes and minor hydrothermal alteration that introduce alkali elements into the silicate framework.

Physical properties described for ofiarekosten in the hypothetical account include a Mohs hardness of about 6.0–6.5 and a calculated specific gravity near 3.2–3.4. Optical properties are reported as refractive indices around 1.62–1.68, with weak to moderate birefringence. Its fracture is typically brittle, and it can be difficult to distinguish from other alkali silicates without detailed petrographic or spectroscopic analysis.

Etymology and naming in the fictional narrative indicate that the name combines a local dialect root meaning “stone” with a regional suffix used for rare minerals, chosen to honor the researchers who described the mineral in the scenario. In this non-real context, ofiarekosten serves as an example of mineral-naming conventions and the kinds of environments in which rare silicates might be discussed.
