Tartalmi kivonat: | Sedimentary and volcanogenic-sedimentary manganese ore formation for the determination of main manganese formations characterized by specific features (lithologie, voîcanogenic, facies, tectonic) is discussed. Manganese formations are divided into three main types: platform, transitional (subplatform and subgeosynclinal) and géosynclinal corresponding to large tectonic elements of the earth crust. According to lithologie features every type is subdivided into subgroups of manganese formations — terrigenous, carbonate and voîcanogenic the quantitative correlation of which is different. Taking into consideration difficulties of ascertainment of the true nature of manganiferous solutions main attention was paid to paragenetic connections and rock assemblages accompanying manganese ore-formation during the study of sedimentary manganese ores and metallogeny in different tectonic parts of the earth crust. A genetic classification of sedimentary manganese formations is suggested. Its scheme is: types of manganese formations—subgroups — manganese formations — deposits. |
