Results of geochemical analysis and modeling of Mikuni et al. "Contribution of carbonatite and recycled oceanic crust to petit-spot lavas on the western Pacific Plate" v.2
Abstract:
This dataset includes the 40Ar/39Ar ages, major and trace element compositions, and Sr, Nd, and Pb isotopic ratios of the petit-spot basalts in the western Pacific region. The results of a mass balance-based melting model are also provided. These results confirms the involvement of carbonatite melt and recycled crust in the source of petit-spot melts. It provides insights into the genesis of tectonic-induced volcanoes, including Hawaiian North Arch and Samoan petit-spot-like rejuvenated volcanoes, that have similar trace element composition to petit-spot basalts.
This dataset is updated version of that previously published.
