Manganese nodules are generally considered to have accumulated very slowly. Radiometric studies by 230Th, 231Pa, and 234U/238U suggest their growth rates to be a few mm per 10... -
Radionuclides in Manganese nodules
Manganese nodules are considered to have accumulated in general very slowly: surface layers of nodules contain a large excess of 230Th, more than would be produced by uranium... -
Structure and chemistry of TECHNO encrustations
Using as a starting point the results giving 'traditional' growth rates as determined by the decrease of radioelements (part I) and the hypothesis of rapid formation, the... -
TECHNO encrustation description and analysis
The distribution of radioactivities in a large polymetallic encrustation (TECHNO) sampled from the Pacific sea floor has been studied in great detail. The study includes...
