Alluaivite

Silicate mineral

Alluaivite is a rare mineral of the eudialyte group with complex formula written as Na19(Ca,Mn)6(Ti,Nb)3Si26O74Cl·2H2O. It is unique among the eudialyte group as the only titanosilicate (other representatives of the group are usually zirconosilicates). The two dual-nature minerals of the group, being both titano- and zirconosilicates, are labyrinthite. They both contain alluaivite module in their structures. Alluaivite is named after Mt. Alluaiv in Lovozero , Kola Peninsula , where it is found in ultra-agpaitic
