Chemical characteristics of zircon from A-type granites and comparison to zircon of S-type granites

Popis výsledku v původním jazyce

The trace element content in zircons was investigated using back-scattered electron images and electron microprobe analyses. The studied Proterozoic (Wiborg batholith, Finland and Pará, Amazonas and Goiás states, Brazil) and Variscan (Krušné Hory/Erzgebirge, Czech Republic and Germany) plutons cover a wide range of rocks, from large rapakivi-textured geochemically primitive plutons to small intrusions of rare-metal granites. The zircon from the non-mineralized plutons is poor in minor and trace elements; the zircon in moderately fractionated granite varieties is slightly enriched in Hf, Th, U, Y, and HREEs; whereas the zircon in highly fractionated ore-bearing granites may be strongly enriched in Hf (up to 10 wt% HfO2), Th (up to 10 wt% ThO2), U (up to10 wt% UO2), Y (up to 12 wt% Y2O3), Sc (up to 3 wt% Sc2O3), Nb (up to 5 wt% Nb2O5), Ta (up to 1 wt% Ta2O5), W (up to 3 wt% WO3), F (up to 2.5 wt% F ), P (up to 11 wt% P2O5), and As (up to 1 wt% As2O5).
