Platinum is markedly enriched over palladium in ferromanganese minerals compared to seawater concentrations of these two elements. This anomalous behavior, similar to that of cerium in the rare earth series, is attributed to the oxidation of platinum from the dissolved divalent state in seawater to the tetravalent state during mineral formation. The platinum to palladium weight ratio in seawaters is around 4.5, in marine sediments around 1, and in ferromanganese nodules between 50 and 1000. Platinum, similar to palladium, shows a nutrient-type profile in seawater.
