Ore Content of Cobalt-Rich Ferromanganese Crusts of the Govorov Guyot of the Magellanic Mountains of the Pacific Ocean

The main ore minerals of all layers of cobalt-rich ferromanganese crusts of Guyot Govorov of the Magellanic Mountains of the Pacific Ocean are poorly crystallized, poorly structurally ordered Fe-vernadite, Mn-feroxigite. A sufficiently structurally ordered vernadite, which is mainly found in layer I–1 and in a smaller amount in layer I–2, has also been identified as goethite. As an impurity, asbolan-buzerite and buzerite-I are noted. The distribution of cations of non-ferrous, heavy, rare, and rare-earth elements in the layers of Govorov Guyot crusts indicates that they are clearly unevenly supplied to the cobalt-rich ferromanganese crusts.
