Dualite is a very rare and complex mineral of the eudialyte group, its complexity being expressed in its formula Na30(Ca,Na,Ce,Sr)12(Na,Mn,Fe,Ti)6Zr3Ti3MnSi51O144(OH,H2O,Cl)9. The formula is simplified as it does not show the presence of cyclic silicate groups.The name of the mineral comes from its dual nature: zircono- and titanosilicate at once. Dualite has two modules in its structure: alluaivite one and eudialyte one. After alluaivite and labyrinthite it stands for third representative of the eudialyte group with essential titanium.

- Das Mineral Dualith ist ein sehr selten vorkommendes Ringsilikat aus der Eudialytgruppe mit der chemischen Formel Na30(Ca,Na,Ce,Sr)12(Na,Mn,Fe,Ti)6MnTi3Zr3[(OH,H2O,Cl)9|(Si3O9)4|(Si9O27)4 · 3 SiO]. Die in den runden Klammern angegebenen Elemente können sich in der Formel jeweils gegenseitig vertreten (Substitution, Diadochie), stehen jedoch immer im selben Mengenverhältnis zu den anderen Bestandteilen des Minerals.

Die in den runden Klammern angegebenen Elemente können sich in der Formel jeweils gegenseitig vertreten (Substitution, Diadochie), stehen jedoch immer im selben Mengenverhältnis zu den anderen Bestandteilen des Minerals. Dualith kristallisiert im trigonalen Kristallsystem und konnte bisher nur in Form xenomorpher Körner von 0,3 bis 0,5 Millimetern Durchmesser von gelber Farbe bei weißer Strichfarbe gefunden werden.
