Fluid effect on zircon O and U-Pb isotopes during ultrahigh-pressure metamorphism: Insights from the Dora-Maira Massif of the Western Alps

[Display omitted] •Coesite in the relict magmatic domains suggest fluid metasomatism at UHP metamorphism.•The metamorphic zircon domain shows Pb loss without O isotope modification.•The metasomatically grown zircon domains exhibit both Pb loss and modification of O isotope compositions.•The fluid ef...
