Galileiite
Galileiite is an IMA-recognized mineral species in the phosphate class, with the chemical formula NaFe²⁺₄(PO₄)₃.
It crystallizes in the hexagonal crystal system (space group R-3). It is a member of the Fillowite structural group.
Key properties: Mohs hardness 4; specific gravity 4.07; optically uniaxial.
IMA symbol Gll, IMA status: approved, named in 1996.
Very rare, as inclusions within troilite nodules in type IIIAB iron meteorites.
It is found associated with Ca-free sarcopside or graftonite, chromite, troilite.
The mineral was named to honor Galileo Galilei (1564–1642), Italian astronomer and poet.
