Radiochemical analyses have been performed on 500 mg of each carbonate rich sediment sample (i.d., carbonaceous clay or mud) and 2 g for carbonate devoid samples (i.d.,...

The manganese content of 4 manganese nodules was determined by atomic absorption. The decrease of total alpha activity was used to evaluate Mn accumulation. Because CaCO3 is a...

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...

For a pelagic sediment core taken in the Atlantic Ocean, The decrease of unsupported 231Pa was used for the determination of the accretion rate. Because CaCO3 is a Mn-free...

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...

For 7 pelagic sediment cores, the decrease in unsupported 130Th activity with depth in the core was used to establish the mean accumulation rate over the last 300 000 years....

For 27 pelagic sediment cores, the Brunnes-Matuyama magnetic reversal boundary (700 000 yr) was used to establish the mean sedimentation rate between this level and the core...
