Short-lived radiogenic W isotopic data for Reunion hotspot ocean island basalts and Deccan Traps continental flood basalts, complemented with additional Nd and Hf isotopic data. The dataset is used to constrain the Hadean heritage of mantle sources to Reunion hotspot volcanism, including possible interactions with Earth's core. The Nd-Hf isotopic data aid in correcting data for Deccan samples for possible influences from crustal and lithospheric assimilation.
