Concentrations of the rare earths have been determined in ten modern manganese nodules from the Atlantic, Pacific, and Indian Oceans, the Baltic Sea, and Lake Charlotte in Nova Scotia. A nodule from a Paleozoic era sea in Montana, a manganese film from a coral found on the Mid-Atlantic Ridge, and samples of the manganese and phosphorite pavements fround on the Blake Plateau were also analyzed. The manganese pavement, a mixed manganese-phosphate concretion from the Blake Plateau and one of the Atlantic nodules with its underlying red clay core were segmented and analyzed. Author
