(Table 1) Carbohydrates in different sediment types of the Central Pacific
Total contents of carbohydrates were determined in samples of natural sediments of various genetic types. Analyses were made on board. Deep-sea pelagic sediments (red clays of... -
Contents of P2O5 and REE in phosphorites from shelves and Pacific seamounts
Recent phosphorites from the Namibian shelf are characterized by low REE contents, depletion in REE compared to host sediments and sharp deficiency of lanthanum and europium. In... -
Uranium and radioactive isotopes in bottom sediments and Fe-Mn nodules and cr...
The main stages of the sedimentary cycle of uranium in modern marine basins are under consideration in the book. Annually about 18 thousand tons of dissolved and suspended... -
Carbohydrates in waters and sediments
The book is devoted to study of diagenetic changes of organic matter and mineral part of sediments and interstitial waters of the Pacific Ocean due to physical-chemical and... -
Composition of marine phosphorites and phosphate-bearing sediments
The book deals with behavior of phosphorus and its concentration in oceanic phosphorites. The major stages of marine geochemical cycle of phosphorus including its supply to... -
Chemical composition of ocean phosphorites and hosted sediments
The book provides an overview of recent data on processes of dispersion and concentration of phosphorus in marine sedimentation. Distribution, chemical and mineral compositions,... -
Abundance of nodules, chemical and mineral compositions of nodules and sedime...
The monograph considers facial conditions of ore-formation in the Central Equatorial Pacific, as well as lithostratigraphy and local variability of bottom sediments. Mineral... -
Abundance and chemical and mineral compositions of nodules from the Pacific O...
The monograph highlights extensive materials collected during expeditions of P.P. Shirshov Institute of Oceanology. We consider facial conditions of nodule formation,... -
Composition of phosphorites from continental margins, seamounts, and islands
Behavior of molybdenum and manganese is studied in phosphorite samples from shelves, seamounts, and islands of the ocean. In shelf phosphorites molybdenum and manganese contents... -
Rare earth element contents and sources in phosphorites from Pacific seamounts
Distribution of rare earth elements (REE) was studied in phosphorites collected from seamounts at depths from about 400 to 3600 m. In general phosphorites are characterized by... -
Composition and sorption capacity of oceanic and marine ferromanganese nodules
Experimental data obtained show that oceanic and marine ferromanganese nodules and crusts are natural ion-exchangers. Exchange capacity of oceanic ferromanganese aggregates is... -
Isotope compositions of oxygen and carbon from phosphates and Fe-Mn crusts an...
Results of a study of phosphates collected on Pacific Ocean seamounts using some physicochemical methods are described. Particular attention is paid to isotopic studies of both... -
Chemical composition of Fe-Mn ores from the North Pacific seamounts
Ore crusts from the Mid-Pacific Seamounts were studied by scanning electron microscopy and by atomic-absorption and chemical analysis. Characteristic ultramicroscopic structures... -
Exchange capacity and chemical composition of Fe-Mn nodules from the Central ...
Constants of calcium, magnesium, zinc, cobalt, copper, and nickel exchange for sodium in iron-manganese nodules taken from different parts of the Pacific Ocean were determined... -
Chemical composition of ferromanganese nodules from the Pacific Ocean obtaine...
Mn nodules from the Pacific ocean were retrieved during expeditions of the R/V Vytiaz and analysed for their chemical composition after separation of soluble (authigenic) part... -
