Dosiahol

Dosiahol is a fictional mineral term used in worldbuilding and speculative fiction. It is described as a rare hydrous silicate mineral that forms in high-pressure metamorphic environments. The name draws from the fictional Dosia region and the -hol suffix used in the world’s mineral nomenclature.

In the fiction, dosiahol crystallizes in the orthorhombic system with a vitreous to pearly luster. Colors range from pale green to teal. It has a hardness of about 5.5 to 6 on the Mohs scale and a specific gravity of roughly 3.2 to 3.6. Its composition is described as variable, with water content influencing color and transparency.

Occurrence and formation: Dosiahol is said to be found in deep crustal shear zones within metamorphic complexes. It forms through metasomatic hydration and dehydration reactions in the presence of magnesium–iron silicates and is often listed as coexisting with minerals such as quartz and serpentine; in some worldviews it appears alongside imagined companions like dosiite.

Uses in fiction: In stories where it appears, dosiahol is proposed as a lightweight, strong material for sculpture or as a speculative energy-storage medium due to purported electrochemical properties. In real-world geology, there is no verified occurrence of dosiahol.

History and usage: The term appears in various worldbuilding texts and science fiction works from the 21st century. It is treated as a fictional construct rather than a scientifically validated mineral.
