JOINT INTERPRETATION RESULTS OF GRAVITATIONAL AND THERMAL FIELDS FOR THE URAL REGION
Аннотация
A method for solving conjugation problems for the Poisson equation is implemented, which makes it possible to interpret potential fields (gravitational and stationary thermal fields) based on unified grid algorithms. A numerical algorithm has been developed for recalculating the mantle component of the heat flow from the level of the earth’s surface to the “crust–mantle” boundary through a layered medium inhomogeneous in thermal conductivity. Paleoclimate corrections were introduced into the measured values of the temperature gradient and heat flux for the northern territories. In the axial part of the Ural geosyncline, it was possible to exclude the negative depression of the mantle component of the heat flow, obtained from the results of geothermal modeling; taking into account the Pleistocene-Holocene warming of the preceding interglacial paleoclimate cycle leads to positive values of the heat flow recalculated to the “crust–mantle” boundary. It is shown that the use of heat flow data can significantly increase the geological information content of gravity modeling.

EVALUATION OF THE GEOMECHANICAL PROPERTIES OF BASHKIRIAN CARBONATE ROCKS AT THE TATARSTAN REPUBLIC FOR OPTIMIZATION OF HYDRAULIC FRACTURING
Аннотация
Every year, the percentage of development of complex and unconventional hydrocarbon reservoirs is increasing, which is associated with the depletion of traditional oil and gas reserves. Carbonate reservoirs are hard-to-recover reservoir rocks due to the high degree of heterogeneity. A more detailed study of the lithological features and physical properties of carbonate rocks is an important and integral part of the complex reservoirs development. In the present work has done a comprehensive analysis of the lithological and geomechanical properties of the Middle Carboniferous strata deposits of the Dachnoye oil field, located in the southeast of the Republic of Tatarstan. The main attention in the research was focused on the estimation of the britleness of rocks. Britleness index is necessary for correct prediction of hydraulic fracturing. The result of the research is the identification of carbonate facies and their geomechanical characteristics, as well as the estimation of the britleness of rocks by various methods.

LOCAL SEISMICITY ANALYSIS OF THE WESTERN PART OF THE TAIMYR PENINSULA ACCORDING TO THE DATA OF THE SINGLE SEISMIC STATION “KOLBA”
Аннотация
In recent years, active development of coal deposits and works related to the creation of appropriate infrastructure (ports, roads, etc.) have been carried out in the western part of the Taimyr peninsula. The main objects are the port Buhta Sever (oil loading terminal), the Syradasay coal deposit and the port Yenisei. Work is also underway in the Lembersk coal mine and the associated port Dixon. The single seismic station “KOLBA” of the Arkhangelsk seismic network installed in October 2020 near Dixson regularly registers local seismic events, the natural nature of which is questioned. From October 2020 to February 2023, 150 seismic events with a magnitude range of ML from 0.4 to 2.4 were registered at distances up to 200 km from the seismic station. The purpose of our research is to give a reasonable answer on the basis of selected criteria about the nature of registered local events: earthquakes or man-made events. Cleaning seismic catalogs from man-made events has always been an urgent task, especially after the installation of each new seismic station in a little-studied area of the Arctic. The difficulty in determining the event nature lies in the absence of a regional hodograph and any reference data such as samples of waveforms, reliable information about the place, time and methods of industrial explosions, the absence of these events on the records of other seismic stations. In this regard, we have defined a set of criteria for determining the nature of events, which are reduced to the consideration of indirect signs. These are the location of an event near an industrial facility, the analysis of spectral-time diagrams and waveforms of seismic events, the analysis of the amplitudes ratio of volume and / waves, the daily distribution of seismic events and the magnitude range of recorded events. Despite the fact that individually each criteria is not a direct proof of the man-made events nature, their totality can be taken as a decision to exclude the event from the seismic catalog. In the process of determining the epicenters of events, we identified several groups related to various industrial facilities. The daily distribution diagram shows that local seismic events were recorded in the daytime with peak values at 13–14 hours and at 19–20 hours, which indicates the technogenic nature of events. The / ratio is < 3.0 for all events, which most likely also indicates a technogenic nature, as with the presence of “bands” in the high frequency range on the spectral-time diagrams. The developed set of criteria for the identification of technogenic events allowed us to clean up the seismic catalog and attribute all 150 events to the manifestation of technogenic seismicity. The most effective criteria are the analysis of spectral-time diagrams, the / ratio and the daily distribution of events. In some cases, by the waveform types, it is also possible to determine whether an event belongs to a certain industrial facility (in particular, to the port of Buhta Sever).

REE SPECIATION IN FLUORIDE-CARBONATE-CHLORIDE COOLING HYDROTHERMAL FLUIDS IN THE PRESENCE OF BARITE AND CELESTINE (THERMODYNAMIC MODELING)
Аннотация
A thermodynamic study was carried out in order to determine the forms of transport for the entire series of lanthanides and their ratio with changing parameters of a hydrothermal fluid of moderate concentrations of chloride, carbonate and fluoride components. Hydrothermal solution, cooling from 500 to 100 ∘C, affected barite and celestine, which are used as a source of sulfate sulfur, monazite as a source of rare earth elements (REE) and phosphorus, and calcite as a source of calcium. It has been established that, under weakly acidic (pH about 4.1) conditions, the equilibrium mineral association is represented by rare earth fluorite, monazite, rare earth fluorapatite, and strontiobarite. In the high-temperature region for light and medium REE, the leading is the first chlorocomplex LnCl+2. For heavy REE, the second fluorine complex LnF+2 takes the first place, except for terbium and dysprosium, for which a sharp predominance of the sulfate complex is revealed. A special picture is observed at 100 ∘C: the leading position is occupied by Ln+3 for both light and heavy REE. In the case of a near neutral weakly alkaline fluid (pH about 7.1), the equilibrium mineral association is represented by calcite, monazite, REE-fluorite, REE-fluorapatite, strontiobarite, and strontianite. The appearance of the latter in natural associations may serve as an indication of the increased alkalinity of the ore-forming environment. In an equilibrium weakly alkaline fluid up to 200 ∘C, hydroxocomplexes are prevalent for all REEs with the ratio Ln(OH)03> Ln(OH)+2. The first chloro complex for light REE at 500–400 ∘C, and the second fluoro complex for medium and heavy REEs follow them. At 100 ∘C, the concentration of hydroxocomplexes sharply decreases, and fluorine and carbonate complexes come to the fore. In general, there is an increased stability of the first chlorocomplex in the high-temperature region, and with decreasing temperature, the role of REE fluorocomplexes increases. Two variants of acidity-alkalinity calculations presumably correspond to modeling of two types of fluids: greisenizing – weakly acidic and carbonatite-forming – weakly alkaline.
