Avanemines

Avanemines is a fictional mineral complex used in educational contexts and science fiction world-building to illustrate mineralogical classification and speculation about crystalline materials. It is not known to occur in the real geological record, but serves as a model for discussing crystallography, phase chemistry, and potential industrial relevance in hypothetical settings.

In the imagined concept, avanemines form in hydrothermal or metasomatic environments where high temperature and pressure drive the integration of metal sulfide layers with silicate frameworks. The structure is often described as layered or polytype, with alternating sheets that can accommodate a range of transition metals. The proposed general composition includes elements such as vanadium, iron, nickel, and cobalt within a sulfide-silicate matrix, with stoichiometry that is intentionally variable to illustrate solid-solution behavior.

Physical properties in the fictional account typically include a metallic to submetallic luster, a Mohs hardness in the mid-range, and a relatively high mineral density. They are portrayed as brittle, with crystal forms ranging from fibrous to tabular, depending on the specific model used by the author.

Etymology in the narrative derives the name avanemines from a fictional Avan region or from a constructed root intended to evoke advanced minerals. In storytelling and pedagogy, avanemines are used to discuss concepts such as mineral classification, phase stability, and potential applications in catalysis or energy storage, while emphasizing that they are hypothetical.
