摘要

Results of the study of Fe-Mn deposits (FMD) from different regions of the Atlantic obtained in several expeditions of research vessels of the Russian Academy of Sciences in 2004-2006 are presented. Materials were gathered at dredging stations during these geological expeditions under the supervision of S.G. Skolotnev. Ferromanganese nodules were dredged at three stations during Cruise 16 of the R/V Akademik Ioffe (Fig. 1). The first and second stations were set up at the southern foothill of the Cape Verde Rise (site 1), where the sedimentary cover is 550 m thick. The study region incorporates the Elena Seamount and other protrusions. Dredging of the northern slope of the Elena Seamount within the depth interval of 4800-4200 m at station 16-03 (11°03.5' N, 26°37.1' W) yielded more than 15 kg of nodules with similar structural and textural characteristics, high density of ore material, and rusty brown color.
