Kastmine
Kastmine is a rare potassium-aluminum silicate mineral commonly referenced in geology education and in world-building for fictional settings. In standard mineralogical terms, it is described as forming in metamorphic environments where potassium-bearing fluids interact with aluminous silicate rocks, producing a durable silicate phase that can crystallize as prismatic crystals.
The name Kastmine derives from the fictional Kast region where the mineral was first described in educational
It is reported to occur in metamorphic belts with granulite to amphibolite facies conditions and is typically
Kastmine is typically colorless to pale yellow, pale green, or brownish; it has a vitreous to resinous
Due to high thermal stability and chemical inertness, Kastmine is sometimes proposed for high-temperature ceramic components
