normilla

Normilla is a fictional mineral used here for illustrative purposes to demonstrate how a mineral entry is written in a concise encyclopedia style. It does not correspond to a real mineral species, and any resemblance to real minerals is coincidental.

Etymology and name origin: The name normilla is constructed from norma, meaning standard or rule in several European languages, with the diminutive suffix -illa. In the imagined context, the term conveys a small standard marker used in teaching mineralogy.

Physical properties: In the hypothetical profile, normilla is described as a transparent to translucent mineral with a pale amber to honey color and a vitreous to slightly resinous luster. It is assigned a Mohs hardness of 5.5 to 6 and a calculated specific gravity around 3.2 to 3.4. The crystal system is listed as monoclinic, with prismatic habit commonly noted in macroscopic specimens.

Occurrence and formation: In the fictional setting, normilla forms in high-grade metamorphic rocks through dehydration reactions at temperatures between 700 and 900 degrees Celsius under moderate pressures. It is imagined to occur alongside minerals such as cordierite and sapphirine in a geologically defined, fictional region, often referred to in teaching materials as Valoria.

Uses and significance: Normilla serves as an educational example for students and writers working on mineralogical descriptions. It may appear in teaching datasets, glossaries, or period-fiction narratives as a placeholder mineral to illustrate data structuring, classification, and descriptive language.
