Chemical composition of the internal layers of manganese deposits from the South Pacific Ocean
The chemical composition of layered deposit inside zones has been determined for ferromanganese nodules and crusts retrieved in the South Pacific Ocean during various R/V Eltanin cruises. Samples were prepared from the nodules and crusts by peeling or scraping successive layers and measuring the res...
