A set of methods has been used for studying composition, structure and distribution of Fe-Mn-micronodules in bottom sediments of the Northeast Pacific. It has been shown that there are two types of Fe-Mn micronodules differing in size, external shape, internal structure and composition of constituent manganese minerals.
