| Summary: | Oxide ores of the global ocean — cobalt-rich crusts and ferromanganese nodules are of bacterial origin and identified as stromatolites and onkolites. Pillar structure of ferromanganese stromatolites and festoon-shaped structures of onkolites represent the bacterial mats, formed by interbedding of fossilized bacterial biofilms. The appearance of ore-forming types of procaryotic family and their evolution are defined by major biosphere events. On the case study of the ferromanganese nodules of Magellanic mountains and cobalt-rich crusts of the province of the Clarion-Clipperton, the main stages of the evolution of structural forms of bacterial communities have been revealed. It has been shown that the change of phases happened due to the influence of major tectonic, volcanic and other geological events. |
