Original language name

Extreme P-, Bi-, Nb-, Sc-, U- and F-rich zircon from fractionated perphosphorus granites: The peraluminous Podlesí granite system, Czech Republic

Original language description

Zircon from the peraluminous Podlesí granite system contain up to 20.2 wt% P2O5 (equivalent to 0.60 apfu, formula calculated on the basis of 4 oxygen atoms), up to 9.0 wt% Bi2O3, (0.086 apfu), up to 6.7 wt% Nb2O5, (0.12 apfu), up to 3.45 wt% Sc2O3, (0.10apfu),up to 14.8 wt% UO2, (0.12 apfu) and up to 3.81 wt% F, (0.42 apfu). Strong enrichment of P preferentially involved the berlinite-type substitution (2Si4+ = P5+ + Al3+). Incorporation of other exotic elements is primarily governed by the xenotime (Si4+ + Zr4+ = P5+ + Y3+), pretulite (Sc3+ + P5+ = Zr4+ + Si4+), brabantite-type (Ca2+ + (U, Th)4+ + 2P5+ = 2Zr4+ + 2Si4+), and ximengite-type (Bi3+ + P5+ = Zr4+ + Si4+) substitution reactions. One part of the anomalous zircons formed late-magmatically, from a strongly peraluminous, P?F?U-rich hydrous residual melt that gave rise to the zinnwaldite granite. Interaction with aggressive residual fluids and metamictization have further aided in element enrichment or depletion.

Zirkon extrémně obohacený P, Bi, Nb, Sc, U a F z frakcionovaného peraluminického granitu, pereluminický granitový system Podlesí, Česká republika

Czech description

Zirkon z peraluminického granitového systému Podlesí obsahuje až 20.2 wt% P2O5 (0.60 apfu, vzorec sestaven na základě 4 atomů kyslíku), 9.0 wt% Bi2O3, (0.086 apfu), 6.7 wt% Nb2O5, (0.12 apfu), 3.45 wt% Sc2O3, (0.10 apfu),14.8 wt% UO2, (0.12 apfu) a až 3.81 wt% F, (0.42 apfu). Silně obohaceny fosfor vstupuje do mřížky zejména díky berlinitové substituci(2Si4+ = P5+ + Al3+). vstup dalších exotických prvků do mřížky je řízen xenotimovou(Si4+ + Zr4+ = P5+ + Y3+), pretulitovou (Sc3+ + P5+ = Zr4+ + Si4+), brabantitovou (Ca2+ + (U, Th)4+ + 2P5+ = 2Zr4+ + 2Si4+), and ximengitovou (Bi3+ + P5+ = Zr4+ + Si4+) substitucí.
