Accumation rates of manganese in manganese nodules using total alpha activity
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... -
Accumation rates of manganese in manganese nodules using differential 230Th-2...
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... -
Accumation rates of manganese in a pelagic sediment core using 231Pa activity
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... -
Accumation rates of manganese in pelagic sediments using 130Th activity
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.... -
Accumation rates of manganese in pelagic sediments using Brunnes-Matuyama mag...
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... -
