THE CRYSTAL STRUCTURE OF SEIDITE-(Ce), Na4(Ce,Sr)2 (O,OH,F)4{middle dot}5H2O, A MODULAR MICROPOROUS TITANOSILICATE OF THE RHODESITE GROUP

Abstract: Seidite-(Ce), Na 4 (Ce,Sr) 2 {Ti(OH) 2 (Si 8 O 18 )}(O,OH,F) 4 •5H 2 O, is a titanosilicate recently discovered in the Yubileynaya pegmatite at Mount Karnasurt, Lovozero alkaline massif, Kola Peninsula, Russia. Grains consist of disordered [010] fibers; no single crystals suitable for X-ray diffraction have found. On the basis of chemical composition, electron and X-ray powderdiffraction data, and by comparison with the structure of miserite, KCa 5 (Si 2 O 7 )(Si 6 O 15 )(OH)F, a structure model for seidite-(… Show more

“…Other minerals identified are tungusite (basalt); charoite occurring in B2, B3, and B5 (silicate); glagolevite (phyllosilicate); mangazeite (hydrated sulphates); falkmanite in B3 (sulphide); augelite in B3 (phosphates); and struvite (phosphates) are not iron-based. Tungusite is formed during the late stages of the post-effusive low-temperature hydrothermal processes under the influence of trap magmas; presumably, hot (about 200 C) hydrothermal solutions rich in Si and Fe interacted with Ca-rich diabases (Ferraris et al 2003). Charoite, falling under the class of silicates, is formed from the alteration of limestones by the close presence of an alkali-rich nephline syenite intrusion.…”
