Data for Tracing Serpentinite Recycling through Heavy Molybdenum Isotopes in Intraplate Basalts

Measured Mo contents and isotopes for NIST 3134, seawater, AGV-2 and W-2a in this study (Table S1); Major-trace elements and Mo-O isotopic data for intraplate alkali basalts from eastern NCB (Table 1); Whole-rock Rb-Sr and Sm-Nd isotope compositions for intraplate basalts from eastern NCB (Table 2); Summary of input parameters for the mixing calculations to understand how much subducted serpentinite is added to the mantle source of intraplate alkali basalts from eastern NCB with heavy Mo isotopes (Table 3)
