Pankratiev P.V., Cotugno A.Y., Sharapov A.F. COPPER MOLIBDENPORFIROVOE GREISEN AND RARE-METAL-ORENBURG MINERALIZATION OF SOUTH URAL The large variety of types of rare-metal mineralization, is currently in the Orenburg southern Ural is not identified the objects of industrial value needed to create the foundations recomendarnos bases in the region. Clarification of regional and local regularities of formation and distribution of deposits of molybdenum will allow for targeted exploration. In article on the basis of generalization and analysis of published and archive materials, the author considers the pattern of distribution molybdenum mineralization in structural-formational zones of the East Orenburg region, distinguished by peculiarities of communication with volcanic and Intrusive magmatism, causing their metallogenic specialization. On this basis, the existence of molybdenum are United in two families: copper-molybdeniferous and rare-metal-greisen. The ratio of Cu:Mo varieties are defined by their (formation). Copper-molibdenovogo family. The ratio of Cu:Mo magnetorheology actually allocated, molybdenum-magnetorheology, copper-molybdeniferous, molybdenum porphyry types of manifestations. They are all associated with the Magnitogorsk volcanogenic troughs of the imposed deflection and the deflections of the East Ural uplift. Enclosing the ore field is confined to volcano-tectonic centers for a long period of development. Thanks polychronic and multi-formational nature of magmatism, mineralization is multistage, polychronic, and in the structure of ore bodies is planned to telescoping. The existence of rare-metal-greisen family is confined to the bodies dwonloding, two-feldspar leucogranites of late Paleozoic (late Permian?) age. Placing productive intrusions is controlled by major regional faults. The main components of this ore type mineralization is molybdenum and tungsten. The research results highlighted prospective areas that have the most favorable conditions for prognozirovanija and evaluation. The analysis of zakonomernostei razmesheniya molybdenum mineralization orenburgskoy region shows that the Orenburg region is highly prospective for the discovery of deposits of rare metals.Key words: copper-molibdenporfirovoe, rare-metal-greisen, patterns, structural and formational zone, family, sub-zone, type of mineralization, specialization, manifestations of mineralization.
