Abstract

Abstract: The rare beryllium silicate, meliphanite, from nepheline syenite pegmatite of the Sakharjok massif, Kola Peninsula has been studied. The chemical composition of the mineral has been refined using infrared and Raman spectroscopy; bulk chemical, thermal, and electron microprobe analyses; and singe crystal X-ray diffraction. The obtained data unambiguously support the presence of H₂O in the mineral and refine the crystal chemical formula of meliphanite from Sakharjok: Ca_4.00(Na_3.12Ca_0.88)_Σ4.00(Be_3.60Si_0.40)_Σ4.00Al_1.00(Si_6.74Be_0.26)_Σ7.00O_24.00[F_3.33(OH)_0.51O_0.16]_Σ4.00.
