In addition to previously known 221 minerals, 11 new rare minerals were identified in alkali pegmatites of the Vishnevye Mountains. Yttrialite-(Y)Y2(Si2O7) and huanghoite-(Ce) aCe(CO3 2F were found for the first time in the Urals. Ancylite-(La)SrLa(CO3 )2(OH) ∙ H2O, baotite Ba4Ti4(Ti3Nb)(Si4O12)O16Cl, bastnäsite-(La) La(CO3 )F, hydroxylbastnäsite-(La) La(CO3 )(OH), hydroxylbastnäsite-(Ce) Ce(CO3 )(OH), parisite-(Ce) CaCe2(CO3)3F2 , fergusonite-(Ce) CeNbO4 , monazite-(La) La(PO4), and lucasite-(Ce)CeTi2 O5(OH) and more abundant arsenopyrite FeAsS and hessite Ag2 Te were found for the first time in the Vishnevye Mountains. The paper describes the mineral assemblages, chemical compositions of minerals, and Raman spectra of some minerals.
