Tootjapartnerite

Tootjapartnerite is a fictional mineral described in speculative geology and in collaborative worldbuilding narratives. It is not recognized as a real mineral by the International Mineralogical Association or other professional bodies.

The name is a portmanteau derived from a fictional locality, Tootja, combined with the suffix -partnerite, echoing mineral names such as dolomite or pyromorphite.

In the lore, tootjapartnerite forms in hydrothermal environments where phosphorus and sulfur-bearing fluids interact with iron-rich host rocks under reducing conditions. It is said to crystallize in slender tabular or prismatic crystals, often showing a blue to violet color and a vitreous luster.

Physical properties commonly attributed in narratives include Mohs hardness 5–6, a calculated density around 3.8 g/cm3, and a brittle habit with a pale gray streak.

Occurrence within the stories is usually tied to fictional deposits in volcanic complexes or subduction-zone analogues; there is no verified locality. In fiction, tootjapartnerite is sometimes proposed for decorative uses, or as a plot device indicating unusual geochemical conditions.
