Abstract:
This dataset includes the whole-rock and mineral chemistry, Sr–Nd–Pb isotopic ratios, and petrography of basaltic, doleritic, and gabbroic xenoliths in a petit-spot volcano on the northwestern Pacific Plate. It provides geochemical and isotopic data that characterize the deeper lithologies of in situ old oceanic crust, offering insights into its formation at the fast-spreading Izanagi–Pacific Ridge (130–140 Ma) and subsequent evolution. This dataset is linked to Mikuni et al. (2025) Marine Geology.
