Turditeetit

Turditeetit is a fictional mineral group introduced in speculative geology and science fiction to illustrate geological processes in subduction-zone settings. The name is invented for world-building purposes and does not correspond to any real mineral. In the imagined taxonomy, turditeetit are described as a silicate mineral group within a basaltic assemblage, characterized by a layered microstructure of intergrown sheets and a secondary oxide phase that creates a distinctive contrast in composition.

Physical properties attributed to turditeetit in fictional depictions typically include crystals that are prismatic to tabular, with a vitreous to pearly luster and a pale blue-to-green hue. The crystals are often portrayed as moderately hard, capable of forming sizeable specimens under suitable conditions, and sometimes displaying subtle pleochroism due to the multi-phase nature of the matrix.

Formation and paragenesis in the imagined scenario involve metasomatic alteration of basaltic rocks under high-pressure, low-temperature conditions, promoting phase separation and exsolution of the second oxide phase. In many narratives, turditeetit occur in subduction-zone environments and are commonly associated with minerals such as magnetite and amphibole, forming a characteristic paragenetic assemblage.

Usage and significance in fiction and teaching contexts position turditeetit as a tool to demonstrate crystallography concepts, mineral paragenesis, and the interpretation of pressure-temperature histories. The concept also serves as a storytelling device to evoke the hidden complexities of planetary crusts and the evolving nature of geological knowledge in speculative worlds.
