Major, trace element and Sr-Nd-Pb-Hf isotope compositions of Tuvalu Island lavas (Rurutu Hotspot)

Major, trace element and Sr-Nd-Pb-Hf isotopic composition of dredged submarine lava samples from the Tuvalu Islands, Southwest Pacific, located between the Marshall/Gilbert Islands and Samoan (western) Seamounts. The purpose of the dataset was to test if the Tuvalu Islands were generated by the Rurutu Hotspot (currently active in the Cook-Austral Islands).
