Abstract

Fe-Mn deposits for this research were sampled at the floor of the Atlantic Ocean in the Cape Verde Quadrangle, Elena Seamount, and Strakhov Basin. The samples were analyzed for major components and for Ni, Co, Cu, P, S, and other trace elements by ICP-AES. Common features in the distribution of REE (high positive Ce anomalies) were discovered, and trends in the distribution of elements with depths are revealed. As, Pb, Sr, Co, and Pt are prone to accumulate in shallower water areas, whereas Cu and Li are enriched at deeper water territories. The samples are analyzed in compliance with Andreev’s classification, and their noble metal composition is determined.
