Abstract:
Sr-Nd-Pb dataset for ocean island basalts from three islands of the Marquesas Archipelago. Data complements and extends those of Castillo et al. (2007 Chem. Geol.) for the same samples. High-precision data for the short-lived 142Nd radiogenic system are included. The purpose of the dataset is to evaluate the time-integrated relationship between different geochemical components of volcanism (FOZO, HIMU, EM) present in the isotopic compositions of Marquesas lavas.
