Ferromanganese
Ferromanganese nodules are primarily centimeter-sized concretions of iron and manganese oxide. They occur on the deep seafloor where pelagic sediment accumulation rates are slow (Baturin, 1988; Pinet, 2000). Some nodules are also found buried in deep-sea sediment cores. Most nodules contain nuclei of different materials (e.g., shark teeth ...
