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 of phillipsites from Core AKO26-35
Behavior of rare earth elements (REE) was examined in oceanic phillipsites collected from four horizons of eupelagic clay in the Southwest Basin of the Pacific Ocean. REE... -
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... -
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... -
