Selivanovaite, ideally NaFe3+Ti4(Si2O7)2O4(H2O)4, is a murmanite-group (seidozerite supergroup) TS-block mineral from the Lovozero massif, Kola Peninsula, Russia. The crystal structure of selivanovaite was refined in space group C-1, a 10.524(6), b 13.815(6), c 12.213(14) Å, α 99.74(6), β 107.45(8)...
