tootemarkide

Tootemarkide is a fictional mineral described in speculative geology and science fiction narratives. It is portrayed as a rare oxide-phosphate mineral with distinctive coloration and proposed functional properties. Because tootemarkide is not recognized by real-world mineralogical authorities, its description varies across works, and there is no single canonical formulation.

Described physical properties in the fictional literature commonly include a tetragonal crystal system with prismatic habit, a vivid blue-green color from copper or vanadium substitutions, a vitreous to glassy luster, and a white streak. Reported hardness is around 6 on the Mohs scale, and the reported specific gravity is approximately 3.4. It is said to be transparent to translucent in well-formed crystals.

In the stories, tootemarkide is formed in deep crustal or upper mantle environments under high pressure, typically associated with ultramafic rocks and metasomatic alteration near subduction zones. It may occur alongside minerals such as zircon, garnet, or perovskite in the fictional paragenesis.

Etymology and naming conventions: the name tootemarkide is a constructed term following the mineral suffix -ide, with the first element derived from a fictional "tootemark" motif used by the discoverers in the narratives.

Uses and cultural impact: within fiction, tootemarkide is sometimes depicted as a decorative gemstone or as a speculative material with semiconductor or energy-storage properties. Its role and properties vary by work, reflecting the speculative nature of its origin.
