Dzhuluite
Dzhuluite is an IMA-recognized mineral species in the oxides & hydroxide class, with the chemical formula Ca₃(SbSn)(Fe³⁺O₄)₃.
It crystallizes in the cubic crystal system (space group Ia-3d). It is a member of the Garnet structural group.
Key properties: specific gravity 4.708; Creamy streak; Strongly vitreous luster.
IMA symbol Dzl, IMA status: approved, named in 2010.
From fluorine metasomatism of a thermally-altered carbonate-silicate xenolith (20 m long) in ignimbrite, the heat from which created sanidinite facies metamorphism in the xenolith.
It is found associated with Kumtyubeite, cuspidine, fluorchegemite, larnite, fluorite, wadalite, rondorfite, hydroxylellestadite, perovskite, lakargiite, kerimasite, elbrusite.
Originally named bitikleite-(SnFe). Subsequently re-named after Dzhulu Mountain, located near the site from which the first specimens were collected.
