Contents of 230Th, Fe2O3, MnO and P2O5 in bottom sediments from the Tropical ...
Shape of the 230Th vertical distribution curve ideally close to exponential is studied to determine isotopic age of deep-sea sediments. In practice such ideal 230Th vertical... -
Contents of radioactive elements, main chemical composition, and sedimentatio...
Gamma-spectrometric analysis was used for six sediment cores from the area occupied by metalliferous sediments in the Southeast Pacific. In five of these cores vertical... -
Humic acids in bottom sediments of the Western Pacific
Elemental composition, functional groups, and molecular mass distribution were determined in humic acids from the Western Pacific abyssal and coastal bottom sediments. Humic... -
Contents of P2O5, Corg, Sr, and Ba in phosphorites and host sediments from th...
Sr contents in phosphorites on shelves of the Southwest Africa, and of Chile and Peru increase with degree of their lithification, from 0.05 to 0.28% and from 0.13 to 0.16%... -
Chemical composition of phosphorites from the Peru and Chile shelves
Recent and Late Quaternary shelf phosphorites have low Fe, Ti and Al contents. These elements enter the phosphorites with terrigenous impurities and organic detritus. Ti, Al,... -
Chemical composition of organic matter in ocean sediments
Group composition of organic matter in recent ocean sediments with high Corg content has been studied in detail. It has been shown that organic matter in sediments with Corg... -
Radiocarbon age of bottom sediments from the Atlantic and Pacific Oceans
Procedures for radiocarbon dating of ocean sediments on board the ship using the benzene variant of the method are described. The main features of the benzene synthesis scheme,... -
Composition of organic matter in deep-sea holoturians and host bottom sedimen...
In 5 holothurian species of the Aspidochirota and Elasipoda orders concentration of organic carbon in alimentary canals due to selective feeding on the average is 7 times higher... -
Composition of bottom sediments from the Guinea Basin
Geomorphology of the Guinea Basin is described along with sediments from cores collected on the abyssal plain, within the abyssal hill zone, and in the eastern part of the Chain... -
Grain size composition of rocks from the Romanche Trench
The paper reports data on composition of rocks and sediments from the Romanche Trench Supplement to: Bogdanov, Yury A; Koshelev, B A; Soldatov, A V (1967): Sediments of the... -
Chemical composition and K-Ar age of basalts from the floor of the Indian Ocean
Petrographic description as well as data on chemical composition and K-Ar age of basalts from the floor of the Indian Ocean are reported in the paper. Supplement to: Bezrukov,... -
Radiocarbon measurements and loose-sediment quantification of seafloor sedime...
Heterozoan carbonates are typical for extratropical sedimentary systems. However, under mesotrophic to eutrophic conditions, heterozoan carbonates also form in tropical... -
Grain size composition of ocean and sea bottom sediments
On the basis of a long term research of the authors a database model of grain size composition of unlithified marine and ocean bottom sediments has been created. An improved... -
Grain size and chemical compositions of bottom sediments from the Amur Bay
Composition of clay minerals in the <0.001 mm size fraction from the uppermost layer of bottom sediments in the northern Amur Bay was determined by X-ray powder diffraction... -
Chemical and mineral compositions of bottom sediments from the East Pacific R...
During underwater photography and sampling of the rift valley bottom in the axial part of the East Pacific Rise, where water transparency is reduced due to hydrothermal input,... -
