Formula:
Na14(Na,Ca,Ce)(Mn,Ca,Ce)[Fe1.55(Zr,Na)(◻,Ti,Nb)]Zr3(Si,Al)(Si3O9)2(Si9O27)2(OH,O)4(F ,Cl) · H2O
originally (Smith & Nickel 2007) reported as Zr3(Mn,Ca,Ce)(Na,Ca,Ce)[Si3O9]2[Si9O27]2[Fe1.55(Zr,Na)(□,Ti,Nb)][Si,Al]Na14(OH,O)4(F,Cl)•H2O
Member of:
Eudialyte Group
Reported as "Mn,Na-ordered analogue of eudialyte" but obviously not a direct chemical analogue of the latter.
