− | | Аннотация = | + | | Аннотация = 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/cm<sup>3</sup> | ||
+ | . The mineral is optically biaxial, positive; N<sub>p</sub>=1.649(2), N<sub>m</sub>=1.651(2), N<sub>g</sub>=1.770(4); 2V<sub>meas</sub>=20(5)°, 2V<sub>calc</sub>=16°. | ||

The ideal formula is | ||
+ | (Sr,Ba,K)(Ti,Nb)<sub>2</sub> (Si<sub>4</sub>O<sub>12</sub>)(OH,O)<sub>2</sub>·3H<sub>2</sub>O (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 <sup>3</sup>. 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. | ||
