� Metallogenic provinces that are potential ore-bearing large volcanotectonic<br />

and dome-shaped uplifts of the ocean floor, usually located<br />

along the boundaries of the abyssal basins;<br />

� Metallogenic regions that are fragments of metallogenic provinces,<br />

located within concrete volcanic-tectonic structures and domes with<br />

directly proven prospects for ore potential of the crustal type;<br />

� Metallogenic fields – fragments of ore regions, confined to individual<br />

guyots with abundant cobalt-bearing ferromanganese crusts, studied in<br />

great detail, with subsequent assessment of their qualitative and<br />

quantitative characteristics;<br />

� <strong>Minerals</strong> deposits – accumulations of cobalt-bearing ferromanganese<br />

crusts, whose reserves and quality satisfy the requirements for<br />

commercial exploitation;<br />

� Mineral occurrences- presumably local accumulations of cobalt-bearing<br />

ferromanganese crusts, which were identified as a result of localized<br />

observations.<br />

All cobalt-bearing ferromanganese provinces in the World Ocean and<br />

the parameters that were included in the database are illustrated in Figure 2.<br />
