geodeettia
Geodeettia is a fictional mineral species commonly used in geology education and speculative mineralogy to illustrate the formation and properties of geode-like cavities. In this context, geodeettia crystals grow on the interior walls of a hollow void, creating a lined cavity that resembles natural geodes.
Etymology and taxonomy: The name geodeettia combines “geode” with the suffix -ia, following standard mineral-nomenclature conventions
Composition and crystallography: Geodeettia is described as an aluminosilicate carbonate with variable alkali content and trace
Formation and occurrence: In the fictional model, geodeettia forms when silica-rich hydrothermal fluids fill cavities within
Uses and significance: As a teaching tool, geodeettia helps students understand geode formation, mineral identification, and
