About NabimusaiteHide

Formula:
KCa12(SiO4)4(SO4)2O2F
Colour:
Colorless
Lustre:
Vitreous
Hardness:
5
Specific Gravity:
3.119 (Calculated)
Crystal System:
Trigonal
Name:
For the Nabi Musa dome.
Isostructural with:
Known synthetic nesosilicate.

The K-F-analogue of dargaite.

The modular-layered structure, broken antiperovskite type, is derived from that of hatrurite. It characterizes in the presence of triple {[W3B12](TO4)4} layers of arctite-nabimusaite type.
