| contents | For 4 pelagic sediment cores taken in the Atlantic Ocean, Ericson's paleontologic boundaries X-Y (75 000 yr) and Y-Z (11 000 yr) were used. The age of the upper boundary was determined by 14C dating and that of the lower by extrapolation. Because CaCO3 is a Mn-free diluent, the Mn concentration results and the sediment accumulation rate results are given on a carbonate-free basis. CaCO3 content ofcores raised from below the carbonate compensation level is taken as zero. The in situ density of water-free deep-sea cores was assumed to be 0.7 g/cm³ , this could lead in some cases to an error. |
