miedon

Miedon is a rare mineral described in speculative mineralogy. It is noted for a glassy luster and a blue-to-green iridescence in transmitted light, arising from a complex aluminosilicate structure that includes iron and titanium and can show variable oxidation states.

The type locality is the fictional Miedo Range within the Integra Highlands, where miedon is reported to form in high-temperature hydrothermal veins that accompany quartz-bearing systems. The mineral is often found in association with magnetite and sulfide minerals, and it is believed to crystallize under moderate-to-high temperatures and varying pressures.

Miedon was first described in 1989 by field geologist Dr. Lena Kord. The name is drawn from the local toponymy of the region and reflects a tradition of naming minerals after geographic features and local linguistic roots. The term has since appeared in academic discussions and world-building literature as an example of a highly aesthetic, yet rare, mineral.

In terms of properties, miedon typically records a Mohs hardness near 6 and a density in the range of 3.7 to 4.2 g/cm3. It exhibits conchoidal to brittle fracture and shows weak cleavage. Under polarized light, it displays pleochroism from pale blue to emerald green, depending on the crystal orientation. The composition can vary within a defined solid-solution series, contributing to its color and optical behavior.

Uses and significance are largely decorative, with miedon valued for cabochon cuts and in collectors’ specimens. In speculative discussions about materials science, its metal content occasionally prompts interest in potential technological applications, though its rarity constrains practical use.
