| Popis | Minerals of the monazite- and zircon-group from several pegmatite dykes near Dolní Bory were studied by EMPA. The results show significant fractionation of Sc and U, but no fractionation of Th in studied minerals during crystallization of the pegmatite dykes. Deep negative europium anomaly was present already in the border zone and is therefore inherited feature of the pegmatitic melt. On the other hand, M-type tetrad effect developed in-situ after dyke emplacement. |
