Cámaraite
Cámaraite is an IMA-recognized mineral species in the silicate class, with the chemical formula Ba₃NaFe²⁺₈Ti₄(Si₂O₇)₄O₄(OH)₄F₃.
It crystallizes in the triclinic crystal system (space group C-1). It is a member of the Seidozerite-Bafertisite structural group.
Key properties: Mohs hardness 5; specific gravity 3.871; Pale yellow streak; Vitreous luster; optically biaxial.
IMA symbol Cám, IMA status: approved, named in 2009.
A hydrothermal mineral in the extensively recrystallized contact zone of a fenitized granite.
It is found associated with Bafertisite, jinshajiangite, zircon, pyrochlore-group minerals, thorite, monazite, xenotime, fluoroleakeite (as inclusions).
The mineral was named to honor Fernando Cámara (b. 1967) of Melilla, Spain, in recognition of his contributions to the mineralogy and crystallography of Ti-silicates, amphiboles.
