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 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.... -
