The manganese content of 7 manganese nodules was determined by neutron activation. The decrease of unsupported 231Pa and 230Th in the outer few tenths of millimeters was used to evaluate Mn accumulation. Because CaCO3 is a Mn-free diluent, the Mn concentration results and the nodules accumulation ra...
