indurite

Indurite is a mineral name that has appeared in a small amount of mineralogical literature but is not widely recognized as a valid mineral species by major reference databases. There is no universally accepted chemical formula, crystal data, or type locality associated with indurite, and its precise identity remains unsettled in contemporary sources.

Nomenclature and history: The name appears to derive from a Latin root related to hardening, but there is no authoritative, widely cited etymology. Descriptions of indurite in the literature are sparse and sometimes inconsistent, and some early mentions may refer to different materials. This has contributed to ongoing confusion about the term’s applicability.

Identity and composition: Without a validated type specimen or formal approval, indurite lacks a standardized composition or structural classification. Reported identifications have varied across sources, and interpretations range from speculative silicate or oxide indications to other mineral classes, all lacking definitive verification.

Occurrence and status: Reported localities for indurite are poorly documented, and modern references generally do not maintain a stable entry for the name. Because of the lack of verification, the status of indurite is often treated as historical or unsettled rather than as a confirmed mineral species.
