In terms of physical and genetic features studied nodules are assigned to the sedimentational manganese-iron type (Canary Basin) and to the iron-containing type (Guyana Basin). They are enriched in Fe, Co and Pb and depleted in Mn, Ni, Cu, and Zn. Cores of the nodules from the Canary Basin consist primarily of peridotite, gabbro, dolerite, and metamorphic rock. Great predominance of peridotite and gabbro indicates that blocks of ocean crust underwent considerable displacement, bringing the third and fourth layers of a crust to the surface.
