Abstract Nanospheres of lead (Pb) have recently been identified in zircon (ZrSiO 4 ) with the potential to compromise the veracity of U-Pb age determinations. The key assumption that the determined age is robust against the effects of Pb mobility, as long as Pb is not lost from the zircon during sub...
