stsenaariumite

Stsenaariumite is a proposed mineral species in the field of mineralogy. It was described in a peer‑reviewed article as a complex silicate-oxide assemblage recovered from a granitic pegmatite. The IMA (International Mineralogical Association) has not yet approved the name, and no holotype specimen is widely deposited, so stsenaariumite remains a provisional designation pending verification.

Composition and structure: The description portrays stsenaariumite as a framework silicate-oxide with a layered arrangement of silicon-oxygen tetrahedra. The chemical analysis indicates a mixed-cation composition dominated by calcium and iron, with substitutions by sodium and manganese; an idealized formulation is given as (Ca,Na)2 (Fe,Mn)4 Si8 O24, with minor titanium and zinc substituting at metal sites. The structure is reported to crystallize in the monoclinic system, forming sheet-like motifs linked through shared oxygens.

Physical properties: Stsenaariumite is described as pale olive-brown to amber in color, with a vitreous to resinous luster. Reported hardness is in the range 5–6 on the Mohs scale, with cleavage described along a single crystallographic direction and a generally micro-crystalline to fibrous habit. Density and refractive indices have not been published with independent verification.

Occurrence and associations: The specimen(s) were reported from a granitic pegmatite body in a tectonically stable region; the locality remains debated and no additional occurrences have been confirmed. Associated minerals include quartz, feldspar, and mica, which are typical of granitic pegmatites.

Etymology and status: The name stsenaariumite is derived from the toponym used in the original description and follows the standard -ite mineral naming convention. As with many recently proposed minerals, confirmation by the IMA and deposition of a holotype are prerequisites for formal recognition.
