daxildir

Daxildir is a rare mineral and a group of related compounds described in the fictional geoscience literature of the Zalnara world. In its in-world taxonomy, daxildir forms in high-temperature hydrothermal veins within subduction-zone rock complexes and is typically found as slender prismatic crystals or as dense vein material. The mineral is described as a complex silicate-oxide containing trace rare-earth elements and exhibits a glassy to submetallic luster with colors ranging from deep blue-green to violet. Under ultraviolet light it can show pale luminescence.

Discovery and naming: Daxildir was first described by field teams led by geologist A. M. Khor in 1987 in the Zalnara Basin. The name combines the Daxiri language root dax- with the mineral suffix -ildir, reflecting the region’s linguistic heritage.

Applications: In the fictional economy, daxildir is valued for its combination of hardness, lightness, and energetic properties. Processed forms include daxildir oxide ceramics and lightweight alloy phases, as well as luminescent pigments. Researchers in the narrative explore its potential in energy storage and optical components, though commercial use remains limited by supply.
