Abstract

REEs geochemistry of the ferromanganese crusts of the Ogasawara Submarine Plateau (Northwestern
Pacific). V.V. SATTAROVA (V.I. Il’ichev Pacific Oceanological Institute, FEB RAS, Vladivostok), Yu.G. VOLOKHIN
(Far East Geological Institute, FEB RAS, Vladivostok).

The contents of rock-forming, rare and rare-earth elements in 4 samples of ferromanganese crusts from the
Ogasawara Submarine Plateau were determined. The REE contents in the studied crusts were 0.21 % on the average. As a result of the study, the character of the distribution of lanthanides in them was determined and a strong positive cerium anomaly was revealed. According to the content of the main ore elements, the crusts of the Ogasawara Plateau are close to ones from the Magellan Mountains and other submarine mountains of the Western Pacific. The presented geochemical data evidence the hydrogenic nature of the studied ore deposits.
