Chemical composition of Pacific manganese nodules using X-ray fluorescence
48 manganese nodules from the Pacific Ocean were selected by the authors for detailed analysis. "Bulk chemical composition" gives, unless otherwise indicated, the results of... -
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... -

Analysis of clay and Mn deposits from the Pacific
The concentrations of Sc, Ti, Fe, Mn, Co, Ni, Cu, La, Th and U have been measured in several Pacific pelagic clays having widely different accumulation rates, 0.4-9.0 mm/103 yr.... -
Elemental composition of various manganese nodules
Manganese nodules have been observed over wide areas of both the Pacific and Atlantic Oceans, however, deposits in the Pacific Ocean are generally much richer in elements of...
