a Crystallization ages of magmatic zircons from ten pre-, syn-, and post-ore igneous rocks (identified from cross-cutting relationship, details in Supplementary Note 1) and a hydrothermal rutile (sample HB-21, syn-ore granodiorite porphyry) associated with chalcopyrite mineralization in Haib, dated using LA-ICP-MS (samples HB-61, HB-28, HB-24, HB-32, HB-33, and HB-30) and CA-ID-TIMS (samples HB-18, HB-51, HB-29, and HB-20) methods. b Zircon Hf isotopic composition (as εHf calculated at 1880 Ma). c Zircon δ18O ratios for representative igneous samples. Filled symbols in (b) and (c) are average values for each sample; smaller pale symbols represent individual analyses. Mantle zircon field in (c) is from ref. 85. Error bars indicate 2σ uncertainties. See Supplementary Data 1 for sample locations and descriptions.
