Jonevelite

Jonevelite is a fictional aluminosilicate mineral created for educational purposes in geology and materials science. It is described as forming under high-temperature hydrothermal conditions and as an uncommon constituent of metamorphic rocks in the fictional Joneval Range.

Crystallography and appearance: Jonevelite is said to crystallize in the monoclinic system, often forming prismatic crystals or crusts. It has a vitreous luster, a pale blue-green color, and is transparent to translucent. Mohs hardness is described as 6 to 7.

Composition and structure: The mineral is described as an aluminosilicate with a framework of aluminum and silicon oxides, balanced by sodium and calcium cations. Trace rare earth elements may be present. This composition places it within a broader aluminosilicate group used in teaching crystallography.

Occurrence and formation: In the fictional account, Jonevelite forms in high-temperature metamorphic settings and hydrothermal veins, with common associations including quartz, biotite, and feldspar. Notable deposits are reported in the Joneval Range but remain speculative in most literature.

Uses and significance: As a teaching example, Jonevelite helps illustrate mineral classification, crystal chemistry, and properties of silicates. There are no known commercial applications, and its status as a fictional mineral means it lacks economic value outside educational contexts.
