Abstract:
At the TAG hydrothermal mound, large amounts of anhydrite in the high-T upflow zone may be responsible for sulphide Delta (super 34) S ratios that are 30/00 heavier than those for all other sulphides at sediment-free mid-ocean ridges. In contrast, the Delta (super 34) S ratios for sulphides and baryte from the propagating tip of the Valu Fa Ridge (Lau back-arc) are the lowest recorded for volcanic-hosted massive sulfides at such centres; this is attributed to magmatic contributions to the seafloor hydrothermal system.
