The examination of polished sections of ferromanganese crusts from the Sea of Japan revealed abundant inclusions of small grains of base and precious metals: Ag, Pd, Pt, Au, Rh, Cu, Zn, Sn, P, Ni, Cr, Ti, Sb, As, W, and Mo. The metals occur in the form of native elements or intermetallic compounds, subordinate sulfides, sulfates, oxides, tungstates, and phosphides. The data on contents, occurrence forms, and distribution of these metals in the ore crusts from this region are discussed.
