DISTRIBUTION AND FEATURES OF MINERAL INDICATORS OF KIMBERLITES FROM INTERMEDIATE RESERVOIRS OF THE VORONEZH ANTECLISE

The mineral indicators of kimberlites (MIK) within the Voronezh anteclise (VA) are distributed unevenly, both along the section and over the area. In the Devonian sediments, the MIK content is low, except for the rocks of the Mamon series in the southeast of the anteclise. Formations of the Aptian and Albian stages contain a record amount of indicator minerals. The Paleogene and Neogene deposits from the MIK are characterized by pyropes and, to a lesser extent, Cr-spinels.

Keywords: Voronezh anteclise, diamonds, Cr-spinels, pyropes, intermediate reservoirs

PETROGENETIC MODEL OF THE SOUTH TATAR ARCH BASEMENT (STA) — THE MAIN PETROLIFEROUS STRUCTURE OF THE SEDIMENTARY COVER OF THE VOLGA-URAL PETROLEUM PROVINCE

The aspects of the deep structure and sedimentary cover of Tatarstan are considered. Scientific material handling of deep and ultra-deep wells has confirmed theoretical assumptions that on the significant depth crystalline basement is not a solid massive. It is an open system, in which gas-saturated solutions can circulate. South Tatar granite- gneissic dome spatially controlling oil bearing area of Tatarstan is characterized by the maximum perspective.

Keywords: athenolithic diapir, gassaturated solution, granite-gneissic dome, crustal granite formation, crystalline basement, oil fields, ultra-deep wells, heat and mass transfer, energy drain system.

INTERPRETATION FEATURES OF THRUST-FOLDED STRUCTURES IN THE AFFORESTED AREAS OF THE BAIKALIA AND PRIMORSKY REGION BASED ON REMOTE SENSING

Thrust-folded structures were identified in the afforested areas by means of structural and tectonic interpretation of remote sensing data using data of spectral bands of the multi-spectral satellite Landsat and calculated vegetation indices NDVI, NDWI. Thrust-folded structures with a Southern and Eastern dip of the thrust surface planes were first identified with a high degree of reliability.

Keywords: Earth remote sensing, Landsat, afforested area, spectral anomalies, NDVI, NDWI, interpretation, thrust, folding.

THE PROBLEMS OF THE GROUNDWATER DEPOSIT SARANSKOE AND THE RESULTS OF ITS OPERATIONS

The article reveals: problems of depletion and pollution of carbon deposits of water-bearing complexes in the exploited areas of the water intakes of «Saranskvodokanal»; changes in the hydrodynamics and geochemical conditions of indicated water intakes as a result of long-term and massive water withdrawal from the deposits of the carbonic complex in the indicated areas; mass water withdrawal as a factor of changes in the geochemical composition of groundwater in these areas. One of the options for identifying patterns of these phenomena and a way to predict further dynamics is 3D modeling.

Keywords: head, piezoisogypsum, depression funnel, mineralization, operational load, depletion

EXPERIENCE OF APPLICATION OF ORE PRECONCENTRATION WITH THE IMPLEMENTATION OF MODERN SENSOR TECHNIQUES

The article provides an overview of the application of modern methods of preliminary concentration of various ore types using sensor techniques and, above all, X-ray absorption (X-ray transmission) sorting (XRT). The physics of the method, limitations, and areas of application are presented. The XRT technology is compared with other methods of preliminary concentration. In addition, numerous examples of the application of the XRT concentration and sorting technique to various types of ores are given.

Keywords: pre-concentration, XRT, X-ray transmission sorting.

ОN TECHNOGENIC CONCENTRATION OF NATURAL RADIONUCLIDES IN DRILL SLUDGE

The problems associated with the increased content of natural radionuclides in the sludge accumulators of the oil-producing enterprise are considered. The forms of finding and concentration of radionuclides affecting the technology of decontamination and utilization of oil-contaminated soils are determined. The main radionuclide, that generates increased γ-radiation, is Ra-226 and its daughter decay products, is isomorphically included in the crystal lattice of the newly formed radiolarite. To solve the issues of oil sludge disposal it is necessary to solve the problem of their radioactive safety.

Keywords: oil sludge, radionuclides, activity, radium, barite, isotope, decontamination, utilization.

THE ROLE ROLE OF THE RELIEF IN THE DEVELOPMENT OF SLOPE PROCESSES ON THE EXAMPLE OF THE ELEGEST-KYZYL-KURAGINO RAILWAY CONSTRUCTION AREA

This article is devoted to the analysis of the relief and its influence on the development of sloping geological processes in the area of the designed Elegest-Kyzyl-Kuragino railway. The territory under study is poorly understood, and therefore there is a need to study natural conditions, as well as to analyze the possibility of slope processes and the possibility of their negative impact on engineering structures. In the work, space images are analyzed and maps of slopes and slope expositions are constructed.

Keywords: Kyzyl, Kuragino, railway, geotechnical processes, space images, slope, slope exposure.
