Crystal chemistry of pyralspite garnets from Shavaryn Tsaram, Mongolia

Popis výsledku v původním jazyce

Garnets from the classic localities in Northern Bohemia (Czech Republic) and Shavaryn Tsaram deposit (Mongolia), of mostly dark red (in some cases dark orange) colour, were studied by means of electron microprobe and X-ray powder diffraction analysis, with the aim to compare the mineralogical compositions of the two sample sets. BSE images were taken to check for potential zoning of the samples. No obvious zoning was observed in the BSE images of polished grains; this is also consistent with the relatively uniform chemical compositions measured . The average empirical formula of Shavaryn Tsaram garnets (based on 12 oxygens per formula unit, full occupancy of all sites, and maintaining charge balance) is (Mg1.56Fe2+0.92Ca0.46Ba0.04Mn0.02)?3.00(Al1.91Fe3+0.08Ti0.03)?2.00(Si2.97Al0.04)?3.00O12. This corresponds to the simplified end-member composition Pyr53Alm31Gr12And4. X-ray powder diffraction confirmed the identity of the studied material to the pyrope?almandine garnet series. Comparin
