- W4385494885 abstract "We present high-precision Ca isotopic data for 21 Cenozoic basaltic lavas from eastern China to evaluate the potential of Ca isotopes as a tool to trace the recycling of surface carbonates. These samples were derived from a variety of peridotite to pyroxenite mantle sources hybridized by different slab-derived agents. The δ44/42Ca of eastern China Cenozoic basaltic lavas ranges from 0.24 ± 0.03‰ (2SE, if not specified) to 0.39 ± 0.03‰, with an average of 0.31 ± 0.09‰ (2SD, N = 21), systematically lower than mid-ocean ridge basalts (MORB, 0.39 ± 0.07‰, 2SD, N = 30). No convincing correlation has been observed with δ26Mg and δ66Zn, indicating that metasomatism by recycled carbonates may not always yield Ca isotopically distinct mantle sources. δ44/42Ca shows correlations with parameters reflecting degree of partial melting (e.g., K2O, Nb, LREE, U, Th, Rb, and Sr) and residual garnet signature (i.e., (Dy/Yb)N). Nevertheless, modeling results suggest that Ca isotope fractionation during mantle and/or slab melting with the presence of garnet can partially account for the observed variable δ44/42Ca. Recycled carbonates with low δ44/42Ca were likely involved in the origins of the lightest lavas. Particularly, the nephelinitic lightest lavas also have the lowest δ26Mg, Ti/Ti⁎ and Hf/Hf⁎ among all the studied samples, reflecting a role of carbonatitic metasomatism in their sources. This study illustrates that a strongly light Ca isotope anomaly (e.g., δ44/42Ca ~ 0.24‰) observed in basaltic lavas is likely associated with the recycling of carbonates into the mantle." @default.
