Hadean components preserved in Paleo- to Neoarchean rocks from the Yilgarn Craton, W-Australia

• First combined short-lived isotopes for southern Yilgarn Craton. • No ¹⁴²Nd evidence for Hadean differentiation in 2.7 Ga mantle sources. • Similar 182 W excesses in 2.6–2.7 Ga and 2.8 Ga granitoids with different sources. • Uniform 182 W excesses in (ultra-)mafic rocks with disturbed W/Th. • W isotope excesses can be explained by missing late veneer. The Narryer Terrane is known for its Hadean zircons, demonstrating the existence of evolved Hadean crust in the Yilgarn Craton (W-Australia). However, the effects of Hadean material on long- and short-lived isotope signatures have remained ambiguous. We present the first combined 146 Sm- 142 Nd and 182 Hf- 182 W dataset for rocks from the Yilgarn Craton to identify putative Hadean components in crustal and mantle reservoirs through time. We investigated these short-lived isotope systems in mafic-ultramafic sequences, metasediments and granitoids covering the oldest preserved Paleoarchean rocks up to the Neoarchean granitoids that mark the stabilisation of the craton. Our study reveals modern mantle-like 142 Nd/ 144 Nd in Paleo- to Neoarchean granitoids and Neoarchean komatiites, suggesting crustal and mantle sources that, at the time of extraction, had already homogenised isotope anomalies from Hadean Sm/Nd silicate fractionation events. We propose that slight µ 142 Nd variations between Williamstown Peridotite, Paringa Basalt, and Kambalda Komatiite samples from the Kalgoorlie Terrane resulted from assimilation of an ancient crustal component. Unlike 142 Nd patterns, many Yilgarn samples show clearly resolvable excesses in µ 182 W that range from +7.5 ± 3.0 to +10.3 ± 2.8 for Paleo- to Neoarchean granitoids and µ 182 W = +4.1 ± 0.8 (95% c.i., n = 11) for Neoarchean mafic-ultramafic sequences. The 182 W excesses likely record isotope signatures inherited from core-mantle differentiation and insufficient inmixing of late veneer material, preserved in the different mantle and crustal reservoirs related to the Yilgarn Craton. Overall, our results demonstrate that the Paleo- to Neoarchean mantle and crustal magma sources had been isotopically homogenised, with limited signatures from Hadean silicate differentiation but had not incorporated the complete late veneer budget of the modern mantle.
