Bazirite
Bazirite is an IMA-recognized mineral species in the silicate class, with the chemical formula BaZrSi₃O₉.
It crystallizes in the hexagonal crystal system (space group P-6c2). It is a member of the Benitoite structural group.
Key properties: specific gravity 3.82; optically uniaxial.
IMA symbol Bzr, IMA status: approved, named in 1976.
A late-stage interstitial mineral in aegirine-riebeckite granite (Rockall Island, Scotland); in granular celsian-bearing rocks near contacts with granite (Big Creek, California, USA).
It is found associated with Elpidite, aegirine, albite, cristobalite, leucophosphite, monazite, quartz, apatite, eudialyte, magnetite, pyrochlore, xenotime, barite.
The name refers to BArium and ZIRconium in the composition.
