Data for: Temperature controlled Se-S isotope fractionation during seawater mixing and sulfide precipitation in black smoker chimneys

This dataset contains the data tables and supplementary tables of the related study of chimney sulfides from the Nifonea black smoker vent field, SW Pacific. The data comprises in-situ major element (EPMA) and trace element (LA-ICPMS) analyses of sulfides. Furthermore powders of micro-domains of chimney sulfides and fresh basaltic glass were analysed for the Se concentration (by HG-AFS), for S isotopes (by EA-IRMS), and for Se isotopes (by HG-MC-ICP-MS).
