Pekov I.V., Chukanov N.V., Zadov A.E., Rozenberg K.A., Rastsvetaeva R.K. TsepiniteSr, (Sr,Ba,K)(Ti,Nb)₂(Si₄O₁₂)(OH,O)₂·3H₂O, a New Mineral of the Labuntsovite Group, p. 11 - 16

TsepiniteSr is a new mineral of the labuntsovite group (the vuoriyarvite subgroup); it is an analogue of tsepinite-Na, tsepiniteK, and tsepinite-Ca, with predominance of Sr among the extraframework cations. Tsepinite-Sr has been found in hydrothermal paragenesis in cavities of nepheline-syenite pegmatite at the Mt. Eveslogchorr in the Khibiny massif, Kola Peninsula, Russia. It is associated with microcline, albite, natrolite, analcime, aegirine, eudialyte, leifite, vuoriyarviteK, tsepiniteCa, kuzmenkoite-Zn, paratsepinite-Ba, takanelite, etc. The mineral forms coarseprismatic crystals up to 0.2 x 0.4 x 2 mm in size and crusts up to 4 x 5 mm. It is translucent, colourless or white; the streak is white, and the lustre is vitreous. The mineral is brittle, without cleavage; the fracture is uneven. The Mohs' hardness is ~5. The measured density is 2.67(2), and the calculated density is 2.63 g/cm³ . The mineral is optically biaxial, positive; N_p=1.649(2), N_m=1.651(2), N_g=1.770(4); 2V_meas=20(5)°, 2V_calc=16°. Chemical composition is as follows (the electron microprobe data, H₂O by TGA, wt %): Na₂O 0.61, K₂O 1.30, CaO 0.92, SrO 5.12, BaO 4.27, MgO 0.01, MnO 0.05, FeO 0.08, ZnO 0.26, Al₂O₃ 0.18, SiO₂ 41.89, TiO₂ 18.49, Nb₂O₅ 16.07, H₂O 11.14, total 100.39. The empirical formula calculated on (Si,Al)₄O₁₂(O,OH)₂ is as follows: (Sr_0.28Ba_0.16K_0.16Na_0.11Ca_0.09Zn_0.02) 0.82 (Ti_1.32Nb_0.69Fe_0.01)_2.02(Si_3.98Al_0.02)₄O₁₂[(OH)_1.89O_0.11]₂·2.59H₂O. The ideal formula is (Sr,Ba,K)(Ti,Nb)₂ (Si₄O₁₂)(OH,O)₂·3H₂O (Z=4). The mineral is monoclinic; space group Cm. The unit cell parameters (from the single crystal data) are as follows: a=14.490(3), b=14.23(1), c=7.881(3) Å, β=117.28(2)° , V=1444(1) Å ³. The strongest lines on the X-ray powder pattern are as follows (d,Å -I (hkl)): 7.10-90 (020, 001); 6.45-50 (200, 20-1); 5.01-40 (021); 3.230-100 (42-1, 400, 40-2); 3.135-80 (022, 041, 24-1); 2.510-80 (44-1, 401, 40-3, 042), 1.728-50 (461, 46-3, 081, 442, 44-4), 1.570-45 (84-1, 820, 84-3, 190, 82-4). The IR spectrum is given. The type specimen is deposited in the Fersman Mineralogical Museum RAS, Moscow. читать далее...
