Distribution of iron and manganese speciations in ocean sediments of a section from the coast of Japan to the open Pacific Ocean is under consideration. Determinations of total... -
(Table 1) Contents of tungsten and other metals in Fe-Mn nodules from the Pac...
Tungsten contents in iron-manganese nodules and crusts from different parts of the World Ocean, as well as its relationships with a number of chemical elements are under... -
(Table 2) Chemical composition of upper and lower surfaces of Fe-Mn nodules f...
Materials of polygon exploration during Cruise 41 of R/V Dmitry Mendeleev showed that diagenetic and sedimentary-diagenetic nodules close in morphology, texture, and composition... -
Chemical composition of Fe-Mn nodules and crusts from oceans and seas
Fluorine concentrations were determined ionometrically with an error of 0.02% in iron-manganese materials of the ocean. They were: 0.02-0.04% in ocean iron-manganese nodules,... -
Chemical composition of Fe-Mn nodules and crusts from the North Atlantic
In terms of physical and genetic features studied nodules are assigned to the sedimentational manganese-iron type (Canary Basin) and to the iron-containing type (Guyana Basin).... -
(Table 3) Contents of phosphorus, iron, and manganese in various zones of Fe-...
Phosphorus content in the surface layer of bottom sediments varies from 0.07% to 0.73%. Clayey radiolarian and radiolarian clayey oozes contain 0.12% P, miopelagic clays 0.21%... -
Geochemistry of surface sediment cores (Table 4)
The mineralogy and geochemistry of a suite of nine manganese nodules from the South Atlantic have been determined. The Ce/La ratios of the nodules were investigated to see if...
