Abstract:
Scandium and lanthanum were analyzed using neutron activation and ICP-MS methods in 60 samples of oceanic phosphorites of various composition and age recovered from continental margins and seamounts in the Atlantic and Pacific Oceans. In the samples studied scandium content ranges from 0.1 to 60 ppm, lanthanum content ranges from 0.4 to 513 ppm, and La/Sc ratio varies from 1.1 to 114. The lowest scandium content occurs in recent phosphorite nodules, intermediate - in Pleistocene phosphatic sand, and the highest - in ancient seamount phosphorites. Process of scandium accumulation in the phosphorites is mainly controlled by their specific surface area and duration of their contact with ocean water. Lanthanum concentrates in the phosphorites much more intensely than scandium. Correlation between scandium and lanthanum distribution is weak, and it appears only when average concentrations of these elements in various groups of samples are compared.
