About Fluorarrojadite-(BaNa)Hide

Formula:
(Ba◻)(NaNa)Ca(Na2◻)Fe2+13Al(PO4)11(PO3OH)F2
Colour:
Yellowish-brown to greenish-yellow
Lustre:
Vitreous, Greasy
Hardness:
4½ - 5
Specific Gravity:
3.61
Crystal System:
Monoclinic
Name:
Named according to the IMA nomenclature scheme for arrojadite group minerals. In fluorarrojadite-(BaNa) Fe2+ is a dominant cation at the M site (so the root-name is arrojadite) and two suffixes are added to the root-name according to the dominant cation of the dominant valence state at the A1 (Ba2+) and B1 sites (Na+). A prefix fluor is added to the root-name as F- is dominant over (OH)- at the W site.
Chemically resembles fluorarrojadite-(BaFe).
