Znondes

Znondes is a mineral species described for its zinc-rich composition and distinctive iridescent sheen. It was first identified in hydrothermal vein deposits in the Kestrel Ridge area and was formally recognized by mineralogists in 2014. The name combines the chemical symbol for zinc (Zn) with ondes, a nod to the wavering colors observed as light moves across its surface.

Znondes occurs primarily in hydrothermal veins within basaltic rock, often in association with sphalerite, quartz, calcite, and galena. Type specimens show tabular to prismatic crystals up to several centimeters in length and are frequently found in radiating or fan-like aggregates. The mineral possesses a metallic luster and a color range from gray to bronze, with a pale gray streak. Reported hardness on the Mohs scale is about 5 to 5.5, and the calculated density is near 4.6 g/cm3. Its crystal structure is described as layered, incorporating motifs that give rise to its characteristic iridescence when viewed from different angles.

Economically, Znondes is regarded as an accessory zinc-bearing mineral rather than a primary ore. It has drawn interest from collectors and researchers for its crystallography and light-scattering properties, rather than for large-scale mining. Current knowledge focuses on its occurrence, formation conditions, and possible implications for understanding hydrothermal processes in zinc-rich systems. Further surveying and analysis are needed to establish its global distribution and potential applications.

Etymology: Znondes derives from the element symbol Zn and the suffix ondes (waves), reflecting light-driven color changes.
