Dosimeetrite

Dosimeetrite is a fictional mineral described in speculative geology and science fiction. It is not recognized by the International Mineralogical Association (IMA) or by major mineral databases, and no verified specimens are known to exist outside of literary or simulated contexts.

Composition and structure: In the fictional description, dosimeetrite is portrayed as a complex aluminosilicate with silicon, aluminum, and trace rare-earth elements. A provisional chemical formula appears as a fictional placeholder (for example, DosSiAl3O12), and the crystal system is presented as monoclinic with prismatic habit. Reported properties include a vitreous to pearly luster, color variations from pale blue to gray, and a Mohs hardness in the mid-range (about 6).

Occurrence and formation: In the narrative, dosimeetrite forms in pegmatitic veins within a mythical Dosimeet region, often alongside quartz, feldspar, and micas. It is described as arising during high-temperature metamorphism and late-stage crystallization in felsic intrusions.

Etymology and naming: The name follows the common mineral-naming convention, combining a fictional Dosimeet region with the -ite suffix to indicate a mineral species. It is explicitly described as a fictional construct rather than a real mineral.

Use and references: The term is used in world-building, teaching simulations, and speculative geology to illustrate mineral-crystal chemistry and metamorphic processes. No peer-reviewed mineralogical literature supports its existence. See also minerals, silicates, and list of mineral names.
