| Popis: | The conditions of the formation of nonmetallic and ore minerals in limnogenic structures are considered. It has been established that lakes are natural enriches of a wide range of useful components - silicate, carbonate, water-soluble, ore, organomineral. The most significant minerals of modern lakes, in addition to water, are: sapropel, diatomite, lime and mineral salts. Deposits of sand, clay, oil shale, oil and gas, coal, phosphorites, zeolites, evaporites, bauxites, ferromanganese, copper ores, placer minerals, and some rare and dispersed elements are associated with limnogenic complexes of different ages. It is shown that a greater variety of minerals of ancient lacustrine complexes compared to modern ones is associated both with variations of lacustrine lithogenesis in the past and with post-sedimentation transformations of sedimentary matter. In particular, epigenetic enrichment of ancient lacustrine complexes with ore components is noted. It was revealed that hydrocarbons and diatomites of lacustrine genesis are of a higher quality compared to similar minerals of marine genesis. It is noted that evolutionary changes in the processes of accumulation of limnogenic minerals have affected to the greatest degree biogenic and chemogenic components. An example of this is the progressive accumulation of caustobiolites and the sulfate evolution of evaporites in lacustrine structures during the Phanerozoic. An analysis of the genetic characteristics of lacustrine minerals makes it possible to develop new exploratory traits of a number of sedimentary deposits. |
