Manganese nodules were retrieved during various cruises of the R/V Vema and R/V Robert Conrad from Lamont Doherty Earth Observatory (LDEO). Their chemical composition was... -
Lead isotope ratios for manganese nodules
The authors have selected manganese nodules broadly representative of world oceanic areas. Approximately 1 gram of each manganese nodules was leached with 25-mi 6N HC1. Lead was... -
Rare earth elements (REE) composition of manganese nodules from the Indian Ocean
Manganese nodules dredged in the Indian Ocean by R/V Marion Dufresne have been selected in conjunction with cores taken in their vicinity. Most of these samples are spherical or... -
