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).本数据集涵盖西南太平洋图瓦卢群岛（坐落于马绍尔/吉尔伯特群岛与萨摩亚（西）海山之间）拖网采集的海底熔岩样品的主量元素（Major element）、微量元素（trace element）及Sr-Nd-Pb-Hf同位素组成数据。本数据集的研究目的为验证图瓦卢群岛是否由鲁鲁图热点（Rurutu Hotspot，当前活跃于库克-奥斯特群岛）所形成。
