Description
| - Five samples of blue, bluish green, and green Fe,Mg-enriched beryl from Li-poor granitic pegmatites [beryl-columbite (LCT) pegmatites at Kovářová and Boněnov in the Czech Republic and Val Sissone in Italy; a primitive pegmatite at Beryller, Untersulzbachtal, Austria; and a euxenite (NYF) pegmatite from the Beryl Pit, Quadeville, Ontario) were investigated using EMPA, Mössbauer spectroscopy, LA-ICP-MS, and powder XRD diffraction. The EMPA data show highly heterogeneous (Kovářová, Val Sissone) to rather homogeneous crystals (Boněnov, Beryller, Quadeville), with high variations in Al (1.51-1.91 apfu), Mg (0.01-0.31), Fetot (0.01-0.18), and Na (0.04-0.37). The substitution CH? + OR3+ ? CHR+ + OR2+ is dominant and supported by the powder XRD data. LA-ICP-MS revealed notable concentrations of some trace elements: Cs ? 7568 ppm (Kovářová), Li ? 928 ppm (Quadeville), Sc ? 2823 ppm (Val Sissone). Beryl samples have mostly comparable contents of Fe3+, ~ 25% at the O-site, but differ in the presence of Fe2+ at the T(2)-site. Primitive characteristics of some examined beryl (Mg/(Mg+Fetot) = 0.37-0.68 reflect low degree of fractionation of the host pegmatite (Beryller), or high degree of Mg-contamination from host metabasites in the pegmatite dikes (Kovářová, Boněnov). The concentrations and ratios of selected elements including Fe3+/Fe2+ in beryl from these Li-poor pegmatites are not feasible for any implications of pegmatite-family affinity or degree of its fractionation except for Li; however, no evident correlation between Li and Cs contents was found.
