Magmatic-to-hydrothermal crystallization in the W-Sn mineralized Mole Granite (NSW, Australia)

Lead and Cs are strongly incompatible in hydrothermal zircon, with estimated zircon-fluid distribution coefficients D ≤ 0.001, while Sn and Li are moderately incompatible, DSn ∼ 0.6 and DLi ∼ 0.1, and Ce is compatible, DCe ∼ 14. Moreover, hydrothermal zircon has a more pronounced negative Eu-anomaly and higher Ta/Nb and U/Th ratios than the magmatic zircons of the Mole Granite.
