dc.description.abstractAlthough carbonates are the primary form of carbon subducted into the mantle, their fate during recycling is debated. Here we report the first coupled high-precision Zn and Mo isotope data for Cenozoic intraplate basalts from western China. The exceptionally high δ<sup>66</sup>Zn values (+0.39 to +0.50‰) of these lavas require involvement of recycled carbonates in the mantle source. Variable δ<sup>98</sup>Mo compositions (−0.39 to +0.27‰) are positively correlated with Mo/Ce, best interpreted as mixing between isotopically light Mo from dehydrated oceanic crust and heavy Mo from recycled carbonates, which is also supported by positive coupling between δ<sup>66</sup>Zn and δ<sup>98</sup>Mo. Modeling reveals that involvement of ≤5% carbonate-bearing oceanic crust fully resolves the observed δ<sup>66</sup>Zn–δ<sup>98</sup>Mo mantle heterogeneity probed by intracontinental basalts. Our study demonstrates that combined δ<sup>66</sup>Zn–δ<sup>98</sup>Mo data sets for mantle-derived magmas can track recycled surficial carbonates in Earth's interior, providing a powerful geochemical tool for deep carbon science.en_US
