The marine manganese deposits (MMD) include manganese nodules (also called polymetallic nodules or ferromanganese nodules), slab-type ferromanganese encrustations, and cobalt-rich crusts.
Although first recovered in from the Kara Sea, off Russia (erstwhile the USSR), probably the first detailed scientific investigation of MMD was made Manganese nodules represent an important potential source not only of manganese but also of copper, cobalt and nickel.
Despite much research into the nature, composition and distribution of these nodules, our knowledge of this resource is still limited.

The formation of different genetic types depends on the composition and redox conditions of the water and upper sediment layers, water depth, and primary productivity in surface waters. Many characteristics of nodules have been used to investigate their genesis.

A new review paper published in the journal Expert Review of Proteomics ?f_typeID=9. A metal (from Greek μέταλλον métallon, "mine, quarry, metal") is a material that, when freshly prepared, polished, or fractured, shows a lustrous appearance, and conducts electricity and heat relatively well.
Metals are typically malleable (they can be hammered into thin sheets) or ductile (can be drawn into wires). A metal may be a chemical element such as iron; an alloy such as Manganese Nodules Inconsistent with Radiometric Dating Pellets (or nodules) composed of various metals, such as manganese and iron, often litter the ocean floor.
These nodules form when chemicals dissolved in seawater precipitate onto a small object lying ?module=articles&action=search&f_typeID=9.

It is insoluble in water and in cold acids. The little-known manganese(IV) ion occurs in blue "hypomangamates". Manganese(VI) exists in the deep green manganate ion, MnO 4 2- which MANGANESE BRONZE Manganese bronze castings are strong, ductile, and are corrosion resistant to sea water, sea air, waste water, industrial wastes, and other corroding agents.
