Osmium in marine sediments
Osmium is enriched in ferromanganese minerals, and its concentrations follow those of other Pt-group metals except Pd. Oxidative capture during solid formation is the probable mechanism for uptake. In some sediments forming under reducing conditions (phosphorites and anoxic coastal deposits) there i...

| description | Osmium is enriched in ferromanganese minerals, and its concentrations follow those of other Pt-group metals except Pd. Oxidative capture during solid formation is the probable mechanism for uptake. In some sediments forming under reducing conditions (phosphorites and anoxic coastal deposits) there is also an enrichment. This may relate to reductive capture, although deposits also formed under reducing conditions from hydrothermal areas are depleted in osmium. |
