Figure 4
Plots to show Mo (EF) versus U (EF) for investigated sections. The solid diagonal line shows the seawater Mo/U molar ratio (1 × SW) and the dashed lines multiples thereof (3 × SW, 0.3 × SW). The olive-green field represents the “particulate shuttle” trend, characteristic of depositional systems in which intense redox cycling of metal, especially Mn oxyhydroxides occurs33.
