Re-Os geochemistry of piston core samples. (a) Re and Os concentrations and isotope ratios. (b) Depositional age determined by Os isotope stratigraphy. Os isotope data for pelagic sediment and Fe-Mn crusts are from refs11,18,48,49,50,51,52,53,54,55,56,57. Measurements were made by the sparging method plus MC-ICP-MS and ICP-QMS (see Materials and methods). Coloured bars indicate stratigraphic and age interval characterised by high Mn concentrations and depositional hiatus.
