Compilation of geochemical data of the Atlantic surface sediments from variou...
Data compiled by E.A. Romankevitch from the following references: Lisitzin et al.,1975; Bezrukov&Lisitzin,1975; Emelyanov & Romankevich, 1979; Romankevich, 1984; Svalnov... -
Rare earth and other element contents in surface layer bottom sediments and f...
Behavior of rare earth elements (REE) and Th is studied along the Transatlantic transect at 22°N. It is shown that both REE and Th contents relative to Al (the most lithogenic... -
Chemical composition in phosphate materials from the ocean floor
Content, distribution patterns, and speciation of Cl in phosphorites and bone phosphate from the ocean floor, as well as in a set of samples from the land are studied. Total Cl... -
Contents of major components, U, and Th in bones and bone debris
Uranium and thorium contents, as well as their distribution patterns have been studied in biogenic phosphates from the Atlantic and Pacific Oceans. Differently lithified fish... -
Age of bottom sediments and minerals from the Atlantic and Pacific oceans
Application of nuclear geochronology methods in study of recent sedimentation processes, in paleoceanology, tectonics, geomorphology, and other problems associated with... -
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... -
Composition of bottom sediments, rocks, and Fe-Mn nodules and crusts from the...
Nuclei of Fe-Mn nodules and bottom sediments along a profile: Guiana Basin - Mid-Atlantic Ridge - Canary Basin have been studied by different methods. Tectoedafogenic and... -
Concentrations of Fe, Mn, Cu, Zn, Co, Ni, Pb, Cd, B, and SiO2 in interstitial...
Chemical analyzes show that interstitial waters from ore-bearing bottom sediments of the Atlantis II and Discovery Deeps are enriched in Fe, Mn, Cu, Ni, Co, Zn, Pb, and Cd... -
Sulfur speciation in bottom sediments from deep-sea basins of the Atlantic Ocean
Distribution of reduced sulfur forms in vertical sediment sections in deep-sea basins of the Atlantic Ocean is under study. Presence of weak sulfate reduction process resulted... -
Chemical and mineral compositions of bottom sediments and ferromanganese crus...
Results of study of bottom sediments near Iceland and on the Jan Mayen Island are reported. It was found that in recent sediments chemical elements are mainly associated with... -
Composition of recent carbonate bottom sediments from the Guiana shelf an off...
This work was based on a study of the upper layer of recent carbonate bottom sediments of the Atlantic Ocean. Biogenic carbonate of recent sediments is represented by metastable... -
Chemical composition of interstitial waters from sediments of brine-bearing d...
Data on concentrations of the major ions (Cl, SO4, Alk, Na, K, Ca, Mg, NH4) in interstitial waters from sediments of three brine-bearing deeps of the Red Sea rift zone are... -
Rare earth elements in bottom sediments from the deeps of the Red Sea rift zone
Analysis of rare earth element (REE) distribution and behavior in ore-bearing hydrothermal-sedimentary deposits from the Red Sea is carried out. Geochemical patterns and... -
Geochemical parameters of sediments and waters in areas of ocean barrier zones
Geochemical barrier zones play an important role in determining various physical systems and characteristics of oceans, e.g. hydrodynamics, salinity, temperature and light. In... -
Sulfur in oceans and seas
The book summarizes results of long-term studies of sulfur geochemistry in bottom sediments of seas and oceans. Processes of hydrogen sulfide formation in bacterial reduction of... -
Planktonic foraminifera and Quaternary paleoceanology of the Atlantic Ocean
An original method of paleotemperature analysis on planktonic foraminifera is substantiated and actively used for stratigraphy of bottom sediments and paleoceanologic... -
Data on the biogeochemical cycle of methane in the ocean
Geological, mineralogical and microbiological aspects of the methane cycle in water and sediments of different areas in the oceans are under consideration in the monograph....
