The coals of the region are characterized by high rare metal potential. Numerous rare metal-coal deposits and manifestations different in composition and nature have been identified. Germanic and scandinous coals are of economic importance. Potentially promising are germanium and scandium containing, gold-bearing and complex rare metalcoal deposits. Coals are characterized by increased REE content compared to carbon clark. The main regularities of distribution and conditions of REM accumulation in coal deposits have been studied. Keywords: coal, rare and rare-earth elements, patterns of distribution, storage conditions, forms of location, metallicity, complex deposits, Uzbekistan. P. 14-19 |

Isotope-gas-geochemical indicators have been determined, the values of which indicate the dominance of epigenetic (migratory) gases from various gas sources in bottom sediments. It has been established that the indicators of the isotopic composition carbon of methane and ethane, molecular weight and gas-geochemical coefficients of hydrocarbon gases of the studied bottom sediments are close in values to hydrocarbon gases of coal-gas-bearing formations, magmatic formations, solid bitumen, condensate-gas, gas-condensate, oil and gas, gas-oil, oil accumulations and coal-oil reservoirs East of Russia.

((Institute of Hydrogeology and Engineering Geology, Uzbekistan, Tashkent) // hydrouz@inbox.uz FEATURES OF HYDROSULFURIC WATERS FORMATION AND TECHNIQUE FOR FORECASTING PROSPECTIVE AREAS OF THE REPUBLIC OF UZBEKISTAN The method of forecasting prospective areas of hydrogen sulfide water formation is described. Geological factors were studied and analyzed in order to clarify the features of the formation of hydrogen sulfide water. Specific natural geological features were identified for each artesian basin. Features of the formation of hydrogen sulfide water in each artesian basin are given. It was clarified that hydrogen sulfide waters are formed due to a biochemical process in the Ferghana and Surkhandarya artesian basins, and in the Bukhara-Khiva due to a thermochemical process. Promising areas of hydrogen sulfide water formation with a complex of specific natural features are recommended. The perspective areas of the southern part of the Ferghana basin, the South-Eastern part of the Surkhandarya basin, as well as almost all the territories (the main Charjou stage) of the Bukhara-Khiva basin are outlined.

The scientific novelty consists in the development of a generalizing characteristic of the ranking of hydrocarbons by classes, taking into account 10 parameters at once, and the combination of the results obtained with the identification of objects by the method of composite indicator of hydrocarbon composition. As a result, it becomes possible, by the geometric position of the new object, to determine the belonging of the hydrocarbon to the saturation class and to resolve controversial questions about the belonging of the identified hydrocarbon in the reservoir to a specific class.

(Labware LLC) // vladstulov@yandex.ru CHEMICAL AND RADIOACTIVE CONTAMINATION OF NATURAL ENVIRONMENTS DURING OIL PRODUCTION The article is devoted to the assessment of chemical and radioactive contamination of natural environments during the production of hydrocarbons (HC). At the same time, the main emphasis is placed on the pollution of ground and surface water, bottom sediments and soils. This article examines little-known facts of direct and indirect impact of hydrocarbon production with long-term consequences for the natural environment. Radioactive contamination was traced in soils, ground and surface waters, and in the Republic of Bashkortostan also in drinking waters. It has been established that in the areas affected by oil production, the aspects of chemical pollution include: deterioration of the quality of groundwater as a result of the ingress of associated water and oil products into aquifers in violation of the technology of drilling oil and gas wells, soil salinization as a result of frequent gusts during the operation of technological equipment. Aspects of radiation pollution of natural environments during oil production include the intake of radionuclides with associated waters, and sometimes with heavy HC fractions (resins, asphaltenes, etc.); the consequences of underground nuclear explosions at oil fields, as a result of which the territory in the zone of their influence has an increased radioactive background. Keywords: chemical and radioactive pollution, oil production, associated waters, radionuclides, consequences of underground explosions, radium, deposits of drinking water. Р. 60-65 |

УДК 539.16 (091) Pechenkin I.G. (VIMS) // pechenkin@vims-geo.ru ABOUT THE HISTORY DISCOVERING OF RADIOACTIVITY It believed that the 1903 Nobel Prize in physics was deservedly award to Henri Becquerel, who «accidentally» discovered previously unknown rays and to the Curies, who selflessly paved the way systematically for future generations of researchers of the secrets of radioactivity. Almost 40 years earlier, Niepce de Saint-Victor described a more correct understanding of the process, ahead of time. Studying various substances to obtain a stable photographic emulsion, he immediately decided that the effect of uranium salts on a photographic plate caused by invisible radiation of matter, not associated with their fluorescence. Nowadays, many give priority in the discovery of radioactivity to Niepce de Saint-Victor. Keywords: radioactivity, Becquerel, Niepce de Saint-Victor, Curie, Brauner. Р. 65-71 |
