Název v původním jazyce
Nannoniite, Al2(OH)5F, a new mineral from the Cetine di Cotorniano mine (Tuscany, Italy)
Popis výsledku v původním jazyce
The new mineral nannoniite, Al2(OH)5F (Z = 4), has been discovered in the Cetine di Cotorniano mine, Chiusdino, Siena, Tuscany, Italy. It occurs as spherical aggregates formed by μm-sized crystals, colourless to white in colour, with a white streak and a vitreous to earthy lustre. Fluorescence is bluish-yellow and white-yellowish under short and long UV radiation, respectively. Electron microprobe analysis gave (in wt%): SO3 0.49, Al2O3 63.97, MgO 0.51, CaO 0.22, K2O 0.07, F 11.72, H2O(calc) 28.54, -O = F -4.94, total 100.58. Nannoniite is monoclinic, space group P21/n, with a = 8.688(3), b = 5.024(2), c = 9.734(4) Å, β = 90.77(2)o, V = 424.9(3) Å3, Z = 4. The crystal structure was solved using three-dimensional electron diffraction and refined to R(obs) = 0.1524 for 2141 unique reflections with I > 3σ(I). Nannoniite is homeotypic with gibbsite. In type material, nannoniite is associated with quartz, baryte, gypsum, and alunite in vugs of silicified limestone. Its origin is probably related to the late-stage circulation of (Al,F)-rich fluids within the Sb ore deposit formerly exploited at the Cetine di Cotorniano mine.
