Mineral and chemical compositions of a ferromanganese nodule from Station DM4...
Processes of authigenic manganese ore formation in sediments of the North Equatorial Pacific are considered on the basis of a study of the surface layer (<2 mm) of a... -
Contents of rare earth and other chemical elements in Fe-Mn micronodules, nod...
Processes governing the formation of rare earth element (REE) composition are under consideration for ferromanganese deposits (nodules, separate parts of nodules, and... -
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... -
Geochemical parameters of bottom sediments from the Tajura Rift, Gulf of Aden
Results of a geochemical study of bottom sediments from the Tadjura rift zone are reported. The sediments were analyzed for CaCO3, Si, Al, Ti, Fe, Mn, Cu, Zn, Ni, Co, Cr, V, Zr,... -
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... -
Chemical composition of ferromanganese nodules from the Black Sea
Ferruginate shells and tubular worm burrows from the oxygenated zone of the Black Sea (Kalamit Bay and Danube River mouth) are studied by transmission and scanning electron... -
Chemial and isotope compositions of rocks from the West Antarctic
The paper is devoted to a marine geophysical-geological research in the West Antarctic. This researche contributed to establishing the base geodesic network of the West... -
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... -
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... -
Temperatures, salinity, wind speed, grain sizes and foraminifera abundance in...
The Great Belt, the largest inlet to the Baltic Sea, has a deep and well defined channel system. A distinct thermohaline layer at roughly 18 to 20 m of water depth separates the... -
Substrate rocks of Fe-Mn crusts on the IOAN and Dalmorgeologiya Guyots
Substratum of cobalt-manganese crusts penetrated by numerous deep-sea drill holes on the IOAN and Dalmorgeologiya Guyots of Magellan Seamounts in the Pacific Ocean has been... -
Geochemistry of Lesser Antilles lavas
We present new U-series disequilibrium and radiogenic isotope data for 7 mafic lavas from the Lesser Antilles arc. These are combined with published data in an internally... -
Sediment and pore water chemistry and physical oceanography of samples obtain...
Sediment samples from approximately 40 stations in the Western, middle and eastern Baltic Sea were investigated for manganese and iron content. In a series of interstitial water... -
Clay minerals in fine grain size fractions from recent bottom sediments of th...
Six regional provinces have been identified in the Gdansk Basin from clay minerals complexes in recent bottom sediments. Mechanism of their formation has been considered. Their... -
