Resumo: | We have studied the hydrated hydroxyl silicate mineral inesite of formula Ca2(Mn,Fe)7Si10O28(OH)_5H2O using a combination of scanning electron microscopy with EDX and Raman and infrared spectroscopy. SEM analysis shows the mineral to be a pure monomineral with no impurities. Semiquantitative analysis shows a homogeneous phase, composed by Ca, Mn2+, Si and P, with minor amounts of Mg and Fe. Raman spectrum shows well resolved component bands at 997, 1031, 1051, and 1067 cm_1 attributed to a range of SiO symmetric stretching vibrations of [Si10O28] units. Infrared bands found at 896, 928, 959 and 985 cm_1 are attributed to the OSiO antisymmetric stretching vibrations. An intense broad band at 653 cm_1 with shoulder bands at 608, 631 and 684 cm_1 are associated with the bending modes of the OSiO units of the 6- and 8-membered rings of the [Si10O28] units. The sharp band at 3642 cm_1 with shoulder bands at 3612 and 3662 cm_1 are assigned to the OH stretching vibrations of the hydroxyl units. The broad Raman band at 3420 cm_1 with shoulder bands at 3362 and 3496 cm_1 are assigned to the water stretching vibrations. The application of vibrational spectroscopy has enabled an assessment of the molecular structure of inesite to be undertaken. |
