Popis: | The important role of the biogenic factor in sedimentary ore genesis now, after more than a hundred years after the publication of V. I. Vernadskys and Ya. V. Samoylovs papers, has become an indisputable fact for everyone. Discussions mainly take place as to how productive the activity of organisms was in the formation of specific exploitable minerals. In 2004, a joint monograph of Russian geologists Biomorphic Structures in Bauxite was published. Using the examples of dozens of deposits of a huge stratigraphic range from the Late Proterozoic age to the Quaternary period and wide geographic range (Africa, Eurasia, Australia and America), active participation of various microbial communities in the bauxite formation was shown in the monograph. This article demonstrates new results of electron microscopic study of ores from Eva bauxite deposit, which is little known in Russia, and continues researching this topic, which was initiated by E. L. Shkolnik. |
