Chemical and radiogenic isotope data of ocean island basalts from Tristan da Cunha, Gough, St. Helena, and the Cook-Austral Islands

Chemical and radiogenic isotope data (Sr, Nd, Hf, Pb) of ocean island basalts from Tristan da Cunha, Gough, St. Helena, and the Cook-Austral Islands. Analytical details for new measurements of Pb isotope ratios are included as a separate file.

本数据集包含来自特里斯坦-达库尼亚群岛、戈夫岛、圣赫勒拿岛以及库克-奥斯特拉尔群岛的洋岛玄武岩（Ocean Island Basalts）的化学与放射成因同位素（锶Sr、钕Nd、铪Hf、铅Pb）数据。其中，铅同位素比值新测定项的分析细节已作为单独文件另行提供。
