| Abstract: | This work is devoted to some problems of the genesis, chemical composition, and forming rates of iron-manganese ores (IMOs)
in the ocean bed due to real outlooks of their development in the years 2015–2020. It is particularly accentuated that ores
are continuously originating on the ocean bed with rates of several millimeters per million years. IMO accumulation in modern
oceans is greatly more than the age of the mobile ocean bed. These unique ores are not only sorbents of some strategic microelements,
but also store easily mobilized oxygen, which is able to supersaturate water in endogenic processes on the ocean bed, blocking
their expansion in a limited volume. Thus, iron-manganese ores must be mined only with nonpolluting methods and under the
control of competent authorities. |
