Pyralspite garnets from Shavaryn Tsaram (Mongolia) compared to garnets from typical Czech localities
Original language description
A garnet of the pyralspite group from the classical locality Třebívlice in the Northern Bohemia (Czech Republic) and that of Shavaryn Tsaram deposit (Mongolia) were analysed using an electron microprobe, Mössbauer spectroscopy and an X-ray powder diffraction to compare the chemical composition and crystal structures of these two sample sets. No obvious zoning was observed in the examined grain as the measured chemical composition demonstrates and the BSE image shows. The average empirical formula basedon 12 oxygens per formula unit, full occupancy of all sites and maintaining of the charge balance for the Mongolian garnet from Shavaryn Tsaram is (Mg1.56Fe2+0.92Ca0.46Ba0.04Mn0.02)?3.00(Al1.91Fe3+0.08Ti0.03)?2.00 (Si2.97Al0.04)?3.00O12 and for that fromTřebívlice (Mg2.11Fe2+0.51Ca0.36Mn0.03)?3.01(Al1.77Cr0.15Ti0.03)?1.95 Si3.03O12 giving following end-member composition: Py53Al31Gr12Ad4 (Mongolian garnet) and Py71Al17Gr12 (Czech garnet). The Mössbauer spectroscopy shows dominance of Fe
