Gritsenko Yu.D., Ogorodova L.P., Vyatkin S.V., Vigasina M.F., Plechov P.Yu., Kalinyuk D.A., Ksenofontov D.A., Melchakova L.V. Investigation of variscite polytypes from the Sary-Sai occurrence, Ulytau region, Kazakhstan, p. 5-18

A physicochemical study of variscite polytypes AlPO4∙2H2O from the Sary-Sai deposit (Ulytau region, Kazakhstan) was conducted using powder X-ray diffraction, electron probe microanalysis, IR, Raman, EPR spectroscopy, and thermogravimetry. The parameters of the rhombic unit cell were determined: for the variscite-1O “Lucin-type” polytype a = 9.8218(17) Å, b = 8.5612(10) Å, c = 9.6278(18) Å and for the variscite-2O “Messbach-type” polytype: a = 9.8971(18) Å, b = 9.664(3) Å, c = 17.184(4) Å. The enthalpy of formation of variscite-2O from elements was determined by high-temperature melt dissolution calorimetry on a Calvet microcalorimeter (–2361.0 ± 4.2 kJ/mol). Its standard entropy was estimated, and its Gibbs energy of formation was calculated (169.5 J/(mol K) and –2129.4 ± 4.2 kJ/mol, respectively). Keywords: Messbach-type variscite-2O, Lucin-type variscite-1O, polytypes, Sary-Sai occurrence, IR spectroscopy, Raman spectroscopy, EPR spectroscopy, thermogravimetry, Calvet microcalorimetry, enthalpy of formation, entropy, Gibbs energy. читать далее...

-| Аннотация = Taeniolite, KLiMg<sub>2</sub>Si<sub>4</sub>O<sub>10</sub>F<sub>2</sub>, was discovered in a strontium-rich carbonatites of the Cenozoic subvolcanic potassium alkaline complex of Dunkeldyk (37<sup>о</sup>46'50''N, 74<sup>o</sup>59'37''E), Eastern Pamir, Gorno-Badakhshan Autonomous Oblast, Tajikistan. Taeniolite occurs as light-brown lamellar grains up to 3 mm in diameter and up to 0.4 mm in thick in a rock, which consists of calcium strontianite (Sr<sub>0.54</sub>Ca<sub>0.46</sub>)CO<sub>3</sub>, fluorite, Sr-bearing calcite, strontianite, Sr-bearing fluorapatite, barite, amphibole group member, which close to magnesio-fluoro-arfvedsonite, aegirine, cancrinite group mineral, ankylite-(Ce) and pyrite. Taeniolite is optically biaxial (–), 2<i>V</i> = 5–10(2)<sup>o</sup>. Refractive indices of the mineral are: <i>n<sub>g</sub></i> = <i>n<sub>m</sub></i> = 1.547(2), <i>n<sub>p</sub></i>= 1.524(2). Taeniolite from the Dunkeldyk massif is characterized with lithium content close to theoretical and extreme fluorine amount. Chemical analysis by electron microprobe (7 points) and LA-ICP-MS for Li gave SiO<sub>2</sub> 58.98, TiO<sub>2</sub> 0.09, Al<sub>2</sub>O<sub>3</sub> 0.23, FeO 0.51, MnO 0.12, MgO 19.89, K<sub>2</sub>O 11.28, Na<sub>2</sub>O 0.38, Li<sub>2</sub>O 3.65, F 9.24, H<sub>2</sub>O 0.07, total 104.44; –O=F<sub>2</sub> –3.88; total 100.57 wt%. The empirical formula, based on 10 O apfu is: (K<sub>0.97</sub>Na<sub>0.05</sub>)<sub>1.02</sub>(Li<sub>0.97</sub>Mg<sub>0.03</sub>)<sub>1.00</sub>(Mg<sub>1.97</sub>Fe<sub>0.03</sub>Mn<sub>0.01</sub>)<sub>2.01</sub>(Si<sub>3.97</sub>Al<sub>0.02</sub>Ti<sub>0.01</sub>)<sub>4.00</sub>O<sub>10</sub>[F<sub>1.97</sub>(OH)<sub>0.03</sub>]<sub>2</sub>. The main absorption bands in the IR spectrum of taeniolite (cm<sup>–1</sup>): 1129, 967, 721, 497, 383. In the Raman spectrum, strong lines (cm<sup>–1</sup>): 184, 258, 295, 307, 334, 701, 956, 1146. X-ray powder pattern of taeniolite is given. Apparently, this is the first discovery of a lithium mineral in the Dunkeldyk carbonatites.<br>
