(VIMS) // alexsandir@gmail.com PETROCHEMICAL AND STRUCTURAL-MATERIAL FEATURES OF GRANITOIDS OF THE DZHETSKIY MOLYBDENUM ORE CLUSTER (VOSTOCHNY SAYAN) The article briefly characterizes the geological structure, reviewed the material composition, features of the petrochemical composition of the granitoids of the Buedzhulskiy and Bellikskiy complexes of the Dzhetskiy molybdenum ore cluster. Based on the peculiarities of the geological structure and our own analytical studies of the distribution of rare earth elements in granitoids, it is shown that the granites composing ore-bearing stocks occupy an intermediate position and are largely independent magmatic formations. Keywords: molybdenum, granites, petrochemistry, Dzhetskiy ore cluster, Buedzhulskiy complex, Bellikskiy complex. Р. 3-7 |

(CNIIgeolnerud) // evbel2018@yandex.ru CLASSIFICATION OF NON-METALLIC MINERALS DEPOSITES OF CHECHNYA REPUBLIC The document below presents the classification of solid nonmetallic minerals deposites, their geo-industrial types and common brief characteristics. The research considers structural position of deposites into tectonic structure of territory of Chechnya Republic, including Skifean plain and nappe-foldblock structure of Great Caucasus. Skifean plate is presented by Caspean Coast and Ters-Sunjen zones. Great Caucasus is presented by Limestone Dagestan, Agvali-Khivean, Arguno-Andean and Major Ridge of Central Caucasus. Ters-Sunjen zone is the most perspective according to localisation of nonmetallic objects. Limestone Dagestan contains a huge amount of raw carbonate. Agvali-Khivean zone contains a few discovered non-metallic objects and some are also predicted in Arguno-Andian zone. Major Ridge of Central Caucasus does not present any industrial meaning. Keywords: classification, geo-industrial, type, position, tectonic structure, solid, nonmetallic, mineral, deposites, manifestations, Chechnya Republic, Russia. Р. 8-17 |

(MGRI-RGGRU, General Department of Geology and Minerals of Vietnam, Hanoi) // dominhphuong.dkt@gmail.com GEOLOGICAL ZONING IN CENTRAL VIETNAM AREA ACCORDING TO THE RESULTS OF PROCESSING MAGNETIC DATA USING «COSCAD 3D» COMPUTER TECHNOLOGIES The article presents the results of processing of magnetic data with the functional content of computer technology for statistical and spectral correlation analysis of data «СOSCAD 3D» for the purpose of studying the hidden magmatic formations and tectonic dislocations in the central Vietnam area. The analysis of the evaluation of the noise component of the magnetic field allows the correction of the available information on the geological structure of the study area. The gradient characteristics of the magnetic field confirm the presence of three main directions of development of the system of tectonic dislocations — southwestern, southeastern and meridional strikes. As a result of zoning the study area by the magnetic field and its attributes, 9 homogeneous areas were identified using cluster analysis algorithms. These are concealed igneous blocks characterized by high values of magnetic susceptibility in the central part of the study area and small geological formations concentrated in the southwest and south. The direct association of the main ore deposits with manifestations of latent magmatism provided an initial estimate of the reserves of mineral ores in the study of the area. Keywords: magnetic field, «COSCAD 3D», Vietnam, statistical attributes, geological zoning, noise component of magnetic field. Р. 27-33 |

(Institute of Hydrogeology and Engineering Geology, Uzbekistan) // elboy.qurbonov@mail.ru FORECASTING ZONES OF FORMATION OF HYDROGEOLOGICAL AND ENGINEERING-GEOLOGICAL PROCESSES IN CONNECTION WITH UNDERGROUND MINING OF SOLID MINERAL DEPOSITS OF THE NURATA-ZARAFSHAN MINING REGION The analysis and assessment of engineering and geological factors in underground development of deposits, predictive assessment of engineering and geological development in natural conditions. Plots are distinguished into three categories: monolithic; weakly fractured, moderately fractured and highly fractured. The stability of the roof and walls of horizontal workings is estimated, the categories of stability are distinguished by the values of the stability coefficient. According to the sustainability assessments, unstable, medium-stable and stable areas in mine workings are divided. The comprehensive accounting of engineering and geological factors and their comprehensive study during geological exploration are given. Keywords: fractured rock, coefficient of fractured voidness, fragmentation, mine workings, specific gravity, volume weight, collapse, collapse. Р. 34-39 |

(TsNIIgeolnerud) // semenovfeodor@yandex.ru) SAND AND GRAVEL RAW MATERIALS AS AN ELEMENT OF THE STRUCTURE OF THE FUND OF COMMON MINERAL RESOURCES — PROBLEMS AND DIRECTIONS OF SOLUTION Sand and gravel raw materials in the structure of the fund of common minerals occupy one of the leading places in terms of the number of explored and developed deposits due to its importance for the country’s construction complex. However, the existing problems: lack of harmonization in natural resource legislation, separate accounting for the extraction of conditioned raw materials and coarse gravel and boulders, the introduction into practice of mining from great depths in water areas; the application of a single tax rate for the extraction of minerals in the water areas of rivers and reservoirs and from the earth’s surface is a limiting factor for the development of a mineral resource base and does not initiate entrepreneurial activity of subsoil users. To resolve them, it is necessary to take a set of joint decisions on the part of the federal executive authorities. Keywords: sand and gravel raw materials, common minerals resource, mineral resource base, processing, construction complex, national project, separate accounting, differentiated production tax, subject of the Russian Federation.

(State Institution «Institute GIDROINGEO» at UGN State Committee for Geology of the Republic of Uzbekistan) // baxtul@mail.ru, hurshida_@rambler.ru HISTORICAL CHRONICLE OF THE FORMATION OF THE LANDSLIDE SERVICE OF THE REPUBLIC OF UZBEKISTAN It is known that the first information about landslides was published at the turn of the XVIII-XIX centuries. In Uzbekistan, studies of landslide processes until the mid-1950s had an episodic character. The mass occurrences of landslides and the tragic events of the spring and summer of 1958 on the territory of the Tashkent region gave rise to the beginning for a systematic study of landslides in the Republic. The impetus for the creation of a unified landslide service in the Republic (the State Tracking Service) was the tragic events of May 4, 1991, when a large landslide destroyed some villages Jigiristian. Keywords: landslide phenomena, landslide service, the origins of the formation, formation, creation of the State Tracking Service. Р. 58-65 |
