Uranium series and Sr, Nd, and Pb isotopic measurements of seafloor hydrothermal samples

Abstract: This dataset contains U-series disequilibria measurements of sulfides and anhydrite collected from seafloor hydrothermal systems. Age constraints derived from U-series disequilibria will be compared with independent age constraints, which will provide important constraints on the utility of uranium series dating of seafloor hydrothermal samples. Sr, Nd, and Pb isotopic compositions are included to evaluate seawater-hydrothermal fluid mass balance.
