Tiheydelle

Tiheydelle is a fictional mineral described in speculative geology and world-building contexts.

According to in-world descriptions, tiheydelle is a hydrated aluminosilicate with trace amounts of titanium and magnesium. It appears colorless to pale violet and has a vitreous luster. Crystals are described as monoclinic and prismatic to tabular, often forming small aggregates within silicate veins.

Geological occurrence and formation: Tiheydelle is said to form in high-temperature hydrothermal conditions associated with subduction-zone volcanism, within basaltic to andesitic rocks. It is typically rare, found alongside minerals such as nepheline, sanidine, magnetite, and other silicates.

Discovery and naming: The term tiheydelle was introduced in 2090 by fictional Eldaran researchers L. Mirov and T. Kestrel. The name is said to derive from Tiheyd, a river in the continent of Eldara, with the suffix elle used in mineral names in that setting.

Classification and uses: In-world, tiheydelle is categorized as an aluminosilicate and is studied as a potential high-temperature ceramic material and coating. Its geochemical behavior is used as a proxy for magma evolution and fluid-rock interaction in speculative geology.
