Nabimusaite is a very rare mineral with formula KCa12(SiO4)4(SO4)2O2F.[2] Its structure, as in case of similar aradite and zadovite, is a derivative of the one of hatrurite.[4] Nabimusaite gives its name to the nabimusaite group.[5] The mineral was found in a pyrometamorphic rock of the Hatrurim Formation, a site known for the natural pyrometamorphism. It is interpreted to have formed due to interaction of a precursor assemblage with sulfate-rich melt.[2] Nabimusaite is potassium- and fluorine-analogue of dargaite.[6]
