| Tartalmi kivonat: | The widely distributed manganese deposits of the world had earlier been classified genetically by PARK [1956]. VARENTSOV [1964] classified principal manganese formations of exogenetic type on the basis of paragenetic associations of rocks. Both the classifications have their limitations. An attempt has been made in this paper to present a genetic-associational classification of manganese deposits. Accordingly the principal manganese deposits of the world can be classified into three broad genetic types e.g. hydrothermal, sedimentary and superficial. The sedimentary type has been genetically subdivided into nonvolcanogenic and volcanogenic types depending upon their source of the metal. Both the nonvolcanogenic and volcanogenic deposits have further been subdivided according to characteristic rock associations. It has been shown, however, that no generalized conclusion can be drawn to relate the associational subdivisions to particular genetic types or any unique tectonic set up, and thus the associational subdivisions have only a descriptive value. |
