The Archean Yilgarn Craton in Western Australia represents one of the key pieces for investigating the mechanisms of crustal growth during Earth’s infancy. The far eastern margin of the Yilgarn Craton, however, has received comparably limited scientific scrutiny. In this study, in-situ zircon petrochronology (U/Pb, O, and Hf isotopes) is used to constrain the formation and evolution of the easternmost Yamarna and Burtville regions of the Yilgarn Craton. The new data highlights the unequivocal existence of relatively old (ca. 2840 – 2777 Ma and ca. 2726 – 2652 Ma), compared to the Eastern Goldfields Terra e, and isotopically mantle-like crust (zircon εHf: +2.1 to +3.5; δ18O: 5.0 to 5.9‰) at the eastern edge of the exposed craton. We refer to this crust as the ‘Dorothy Hills Block’. The Dorothy Hills Block shows geochronological and isotopic similarities with the adjacent ‘Burtville Block’ and Youanmi Terrane, >400 km further west, which suggest at a shared history subsequent to ca. 2970 Ma. In addition, linear greenstone belts characterised by younger magmatism (ca. 2720 – 2660 Ma) with a constant, mildly super-chondritic Hf isotope composition (εHf: 0.0 to +3.5) is identified between the Burtville and Dorothy Hills blocks. We refer to this region as the ‘Yamarna Rift’, by analogy to the better-understood ‘Kalgoorlie-Kurnalpi Rift’. It is inferred that crust in the Burtville and Dorothy Hills blocks formed via peri-cratonic magmatism (ca. <2970 Ma), associated with mantle upwelling focused along the eastern edge of the ca. >3300 Ma Yilgarn proto-craton. The Yamarna and Kalgoorlie-Kurnalpi intra-cratonic (failed) rift basins (ca. 2720 – 2630 Ma) are interpreted to have formed via a major mantle upwelling event, potentially contemporaneous with a west-dipping subduction zone east-northeast of the preserved Yilgarn Craton. The revised crustal evolution model for the ‘Eastern Goldfields Terrane’, including petrochronological data from the far-east region and new nomenclature, suggests both peri-cratonic and intra-cratonic, sustained, and autochthonous geological development during the Neoarchean. Similar crustal evolutionary trends are recorded in other Archean cratons (e.g., Superior Craton), which suggests that similar geodynamic regimes operated on a global scale in the Archean.
