Puheteorian

Puheteorian is a fictional crystalline mineral that appears in speculative geology and science fiction. The term is used to describe a material with a silicate-oxide framework that forms under high-temperature hydrothermal conditions in imagined crustal environments. The name derives from the notional Puhete Formation and uses the suffix -ian to denote a mineral species.

In most depictions, puheteorian crystallizes in hexagonal or tetragonal lattices and exhibits a Mohs hardness around 7.5–8, with a bulk density near 4.1–4.5 g/cm3. It is often described as luminescent under ultraviolet light and as having interesting dielectric and optical properties when doped with trace rare-earth elements or transition metals. The composition is typically portrayed as a complex aluminosilicate with metallic dopants, and the mineral is depicted as chemically stable at high temperatures and resistant to weathering in simulated environments.

Fictional occurrences place puheteorian in oxidized zones of ultramafic to felsic crustal belts, or as a primary product of planetary differentiation in early crusts. Some narratives connect its formation to subduction-like processes or to speculative geologies of other worlds, providing a plausible context for study and extraction.

Synthesis in fiction describes growth under controlled high-temperature, high-pressure conditions, using flux growth or hydrothermal methods to produce sizable crystals for examination or display. Purification and characterization are common plot elements, with researchers analyzing optical, dielectric, and radiation-attenuation properties.

In-universe significance centers on potential applications in photonics, radiation shielding, and robust ceramics, as well as its role as a benchmark for mineral-physics theories under extreme conditions. As a fictional mineral, puheteorian illustrates how new minerals are evaluated in speculative science.
