About FluorstrophiteHide

Formula:
SrCaSr3(PO4)3F
Colour:
Green to yellow-green, colourless
Lustre:
Vitreous, Greasy
Hardness:
5
Crystal System:
Hexagonal
Name:
First named strontium-apatite by Efimov et al. in 1962. It was later changed to apatite-(SrOH) (Burke 2008) despite fluorine being dominant over hydroxyl. It was renamed to fluorstrophite by Pasero et al. (2010). The current name reflects the composition, including dominant fluorine, strontium, and phosphate.
