Abstract:
Selenium content of phosphate material from the ocean bottom ranges from 0.2 to 4.7 mg/kg. Phosphorites of various ages from the Atlantic and Pacific Oceans contain 1.0-2.4 mg/kg of selenium, phosphatized coproliths 0.7-1.2 mg/kg, fish bones 0.2-1,4 mg/kg, and bones of marine mammals 0.5-4.7 mg/kg. Recent diatom muds on the shelf of Namibia are considerably enriched in selenium (12.2-13.8 mg/kg) than phosphorites that form within them. Accumulation of selenium in phosphate material on the ocean bottom results from diagenetic reduction, causing it to be precipitated from liquid phase and to concentrate in organic components and sulfides.
