The Geological Survey of Western Australia (GSWA) released its first statewide samarium–neodymium (Sm–Nd) isotope map under the Accelerated Geoscience Program in 2021 (Lu et al., 2021). Such isotope maps have previously been used to characterize lithospheric architecture through time, and to help understand crustal evolution and mineral system distributions, and play an increasingly important role in predictive exploration targeting (Champion and Cassidy, 2007; McCuaig and Hronsky, 2014; Mole et al., 2015; Champion and Huston, 2016; Wu et al., 2022). Here we present a revised Sm–Nd isotope map of Western Australia that updates previously released data with analyses of 230 new samples, for a total of 2224 analyses (Figs 1, 2).
