3D characterization of the Mila 18 archaeological site in Warsaw, Poland: From imaging to excavation

Archaeological site investigations in urban environments are often beset with challenges such as (1) an absence of buried artifacts due to recent disturbance from infrastructure development or (2) community concerns about potential site impacts from excavations. Noninvasive geophysical surveys that use a combination of methods can help mitigate the risks of uncertain outcomes by identifying areas where culturally significant features are more likely to be uncovered. We show how new technology and traditional geophysical survey methods were used to characterize the subsurface of the Mila 18 Memorial site in Warsaw, Poland. This site is one of the most important places of remembrance for the Holocaust and coincides with the location of an underground bunker that was used by Jewish resistance groups during the 1943 Warsaw Ghetto Uprising. In this case study, we showcase the use of drone multispectral imaging and handheld lidar scanning in conjunction with other geophysical techniques including electrical resistivity tomography, ground-penetrating radar, magnetic gradiometer, twin-probe resistance, and fixed-frequency electromagnetic surveying. The geophysical results were included in an interactive 3D site model to help identify a suitable site for excavation. To document the excavation and to validate and further interrogate the geophysical survey results, we used lidar-based photo-textured scans of the excavation that were incorporated into the 3D site model.

Multichannel GPR and multi-depth electromagnetic surveys for the study of Villa Eucheria and Aquinum at Castrocielo (Frosinone, Central Italy)

The municipality of Castrocielo (Frosinone, Italy) is a historically significant center which includes several centers of great archaeological importance, including part of the archaeological site of the ancient Roman city of Aquinum. In this work, we show the results of geophysical surveys performed in two different areas: the first area is close to the Monacato of Santa Maria al Palazzolo, built on the foundation slab of a Roman villa dating back to the 1st-2nd century BCE; the second area is close to the charging station Casilina Est, where several burials, dating back to different periods from 4th century BCE to 4th century CE, were found. The aims of geophysical investigations is to identify structures linked to the ancient Roman villa (Villa Eucheria) in Area 1, and to identify the tombs of the necropolis in Area 2. The two areas were investigated in two different days, on 27th and 28 th March 2023 respectively, through a multi-channel georadar system (GPR). In the second area, an electro-magnetometric survey was also performed. This choise is to address the heavy rain developed during the night before the acquisition. Infact the GPR survey performed during the second day of the geophysical campaign did not provide good results.Based on the geophysical results, the archaeological excavation in Area 1 confirmed the detected anomalies, documenting a section of wall and other structures and elements brought to light over a length of approximately 9 m. The results obtained in Area 2 confirmed the cropmarks visible in the aerial photo, highlighting the traces of buried structures.

Development of software for automated digitisation of geophysical survey results of underground gas storage wells

The purpose of the work is to store, process and analyse the materials of geophysical surveys of wells (GSW) of underground gas storage (UGS) facilities. In order to reduce the time needed to analyse paper-based GSW data accumulated during the operation of gas storage facilities, it is important to transfer them to electronic form for storage. A set of application software solutions has been developed to achieve the goal.The paper presents approaches to the operational analysis of geophysical information, including its verification, correction and accumulation in digital format. A software package (SP), “Karotazh”, was developed for automated recognition of the results of geophysical surveys of wells, which are important for solving various geological and technological problems by means of prompt processing, systematisation, accumulation of initial information, graphical and documented display of this information. The software for preparation of well logs is designed to enter them into the archive for storage, viewing and further automated recognition (digitisation).In order to solve the tasks set out in the study, it has been used such general scientific methods as systematisation (when selecting the necessary sources of information), generalisation (in the process of defining general terms that highlight the main features), formal logical method, method of systematic analysis of information, descriptive method and modelling method.Implementing the developed software for automated recognition of logging results can increase the efficiency of processing geological and geophysical information on wells and productive horizons to analyse their condition and eliminate complications promptly. Forusers’' convenience, an interface for Ukrainian UGS conditions has been developed, allowing specialists to increase their work’s efficiency. The proposed software solution can be used by oil and gas companies in Ukraine to digitise and provide information support for the analytical processing of geophysical survey results.The approach enables to quickly digitise and analyse well logs and then store them in an electronic archive of geophysical surveys.In order to solve problematic issues in gas storage wells on time, it is necessary to promptly analyse the results of geophysical surveys using modern software tools to predict possible complications and take appropriate measures in a timely manner.Implementation and use of the developed software solution for automated recognition of GSW results at UGS facilities enables to reduce the time for analysis of information in paper form and increase the efficiency of obtaining the necessary information for timely action in case of complications.The authors propose relevant and up-to-date software solutions for the automated processing of GSW results and their storage and use in an electronic archive. Implementing the approach in production enables specialists to quickly analyse information and solve problematic issues.

Characterization of Underwater Landslides in Krui Waters, Lampung-Indonesia using Shallow Seismic and Sonar Data

Abstract Krui Waters, Lampung, Indonesia, is an area that has the potential for a tsunami disaster. Local tsunamis can be caused by underwater landslides owing to ground movement and gravitational forces. Imaging underwater conditions using sonar and shallow seismic systems is an interesting research topic for geological disaster researchers. Underwater landslides are very important for disaster mitigation, especially for tsunami prediction. This research aims to identify the characteristics of underwater landslides around Krui Waters, Lampung, Indonesia, using imaging analysis methods from sonar data and a sub-bottom profiler (SBP). The underwater landslide phenomenon in this area is still not known in detail, and therefore requires further research. All data were obtained from the results of hydrographic, geological, and geophysical surveys of RV Baruna Jaya IV in 2020. The sonar data shows surface characteristics such as the presence of Furrows (Gravel Waves), Cobble (Boulder), as well as Canyons and landslides or mass movements rocks. SBP data show the characteristics of the seabed in the form of a canyon with a slope greater than 160. Finally, the morphological characteristics and features obtained could possibly be a potential source of local tsunamis owing to the high slope.

Використання комплексу газогрунтової зйомки та геофізичних досліджень у задачі окреслення території грязьового вулканізму в межах Розвадівської площі Львівської області

The purpose of the research was to substantiate the scientific basis behind the formation of a mud volcano within a specific section of the Precarpathian depression. It also aims to examine the existence of a near-fault shallow gas deposit in the Rozvadiv area and its possible impact on gas-soil surveying and electrometry fields. The relevance of the work is determined by the need to solve the ecological problem of environmental pollution with hydrocarbon gases, as well as to establish and forecast the degree of emissions of the gas-mud mixture. At the same time, the problem of the presence (or absence) of the relationship between the influence of the Rudnyk gas-prospecting area, which is impacted by drilling, and the Rozvadiv deposit mentioned above is solved by comparing the results of gas-soil and geophysical surveys on a significant territory covering the specified areas. The research methodology consists of the following: 1) application of research with different physical justifications (gas-soil survey and electrometry); 2) comparison of the survey results from the same area and the same grid of observations; 3) detection of anomalies within the studied territory and their interpretation from the point of view of the development of mud volcanism. Research results. The information basis of gasometry involves direct measurements of free gas in a observation regular system in the soil environment atmosphere, their statistical characteristics, and calculated indicators of gas contamination. Therefore, the gas distribution maps are informative. The applied research using the method of Earth’s natural pulsed electromagnetic field made it possible to differentiate the area according to the intensity degree of electromagnetic radiation, taking into account the different depths of the sources, and, thus, identify areas of stressed-strain state of rocks and qualify them by the causes. The scientific novelty lies in the following: 1) indicating the absence of connections between the massif impacted by drilling and a natural disaster; 2) specifying the causes of the natural disaster and its substantiated mechanism and classifying the event as a mud volcano. Practical significance. Interpretation of the obtained results makes it possible to determine the causes of the extraordinary geological event in the Rozvadiv area of the Lviv region, classify the event and its consequences as a manifestation of elements of mud volcanism, and establish the absence of a relationship between the specified event and man-made impact (drilling) of the geological environment in the neighbouring areas.

Перспективы использования инженерно-геофизических методов на гидроузле реки Ирелях (Западная Якутия)

The construction of hydraulic structures in the permafrost zone leads to the formation of local sources of hydrogenic thawing. The process of formation and expansion of subchannel natural-technogenic talics requires permanent study and monitoring, including the use of new and adaptation of existing methods of engineering geophysical research. The paper examines the results of engineering geophysical surveys aimed at studying the actual engineering, technical and cryohydrogeological state of the drinking water reservoir on the Irelyakh River. The scope of the work included following methods: electrical profiling, natural potential, vertical electrical sounding, dipole sounding, and thermometry. Based on the results of the study, it was determined that the natural-technogenic talic in the terrigenous-carbonate rocks at the base of the reservoir currently continues to develop. Continuous development in the infiltration zone, as well as at the discharge front and observed flow rates has been observed. The thickness of the thawed rocks in the upper reaches of the river, according to the results of geophysical data, does not exceed 20 m, and in the lower reaches of the dam is already at least 100 m. The dynamic nature of the development of the object under study requires continuous engineering and geophysical monitoring to be carried out on a regular basis.

Investigation of Ambient Seismic Noise in Different Region of Georgia

Georgia, like the whole South Caucasus, is a tectonically and structurally complex region. It is one of the active segments of the Alpine-Himalayan belt, therefore it is important to assess the seismic hazard for Georgia. At the regional scale, this assessment is evaluated by applying probabilistic seismic hazard analysis that identifies the annual probability of exceedance of various ground motion levels defined in terms of selected ground motion intensity measures, such as PGA or spectral accelerations (SA) corresponding to various return periods related to possible future earthquake scenarios for a site represented by soil classes A according to EC8, Euro-code 8-EN 1998-1 (1998). At the local scale, seismic hazard assessment is made by analyzing the geological, geomorphological, geotechnical and geophysical characteristics of the site, as it is well established that the incoming seismic motion can change in amplitude, frequency, and duration due the site-specific local characteristics. That is the subject of micro-zonation investigation. Site – specific local characteristics are presented by the following parameters: Dominant frequency, Vs,30 (average shear-wave velocity to a depth of 30 meters) and amplification factor. In this work, we presented results of geophysical survey assessing local site conditions by dominant frequency that allows identification of similar seismic response areas. For this purpose, seismic noise records have been used first time in Georgia.

Heat Flow Prediction in Songliao Basin Based on Deep Neural Network

The heat flow is the key data for accurately predicting the contribution of underground heat, but due to the high cost of measurement, the spatial difference is huge, and the heat flow information in some areas is little known. This paper uses deep neural network technology to perform machine learning on a large number of relevant geological and geophysical features and heat flow measurements on a global scale. In addition, the model uncertainty quantification process is introduced, and the reliability of the prediction results is discussed based on the global sensitivity analysis and correlation calculation of the deep learning method. Finally, for the distribution map of heat flow and absolute difference in the Songliao Basin in the study area, the measured data error is less than 11%, and the predicted absolute difference is less than ±20 mW/m2. The results prove the accuracy of the method and the abnormal high heat flow in the central region of the basin. The existence of, further combined with the results of geophysical surveys, provides evidence for the analysis of regional thermal causes.

Geophysical investigation of Gnezdilovo-12 burial mound necropolis (Suzdal Opolie)

We present the results of geophysical survey of the burial mound necropolis Gnezdilovo-12, which has been completely destroyed by ploughing. The results of geophysical data interpretation are compared with the results of archaeological excavations, XIX c. maps and surface artefacts distribution, showing good correlation between the datasets. For the European part of Russia the investigation of Gnezdilovo-12 is one of the first examples of full-scaled geophysical survey of the destroyed burial site, which enabled the confident interpretation of the site structure and 3D reconstruction of the burial mound landscape.

Geodynamic Aspects of Magnetic Data Analysis and Tectonic–Paleomagnetic Mapping in the Easternmost Mediterranean: A Review

The Easternmost Mediterranean is a transition region from the ocean to the continent where the spreading and collision zones of the lithospheric plates join. The methodology of paleomagnetic mapping of the transition zones is based on combining geological and geophysical techniques for continental and oceanic platforms: magnetic data interpretation, paleomagnetic reconstructions, results of magnetized rock radiometric dating, satellite data analysis, tectonic–structural reconstructions, biogeographical studies, and utilization of different geophysical survey results. The satellite-derived gravity map reflects practically all significant tectonic units in the region, which assists us in the supposed paleomagnetic mapping. The satellite-derived and aeromagnetic maps with the tectonic features and the map of Curie discontinuity of Israel indicate the complexity of this region. Advanced magnetic data analysis supported by paleomagnetic data attraction and other geological–geophysical methods allowed the revealing of the block of oceanic crust with the Kiama paleomagnetic zone relating to the Early Permian age. A narrow reversely magnetized Earth crust block was revealed in the Lower Galilee. Some examples of advanced magnetic anomaly analysis are presented for several areas where the magnetization vector inclination is other than the modern direction: the Sea of Galilee, Carmel, Rosh-Ha-Ayin, Malqishon, and Hebron. In Israeli land, for the combined paleomagnetic mapping, the well-studied using paleomagnetic and radiometric methods (as well as tectonic–structural) areas were selected: (1) Makhtesh Ramon, (2) the Sea of Galilee with the adjoining zones, (3) Carmel, (4) Hula, and (5) Hermon. It is shown that the regional analysis of paleomagnetic data distribution played an essential role in detecting the influence of the recently recognized counterclockwise rotating mantle structure on the near-surface layers.

In situ bottom sediment temperatures in the Siberian Arctic seas: Current state of subsea permafrost in the Kara sea vs laptev and East Siberian seas

Features of sediment temperature on the shelf and continental slope areas of the Russian Arctic seas and its physical properties are important for understanding the current state of subsea permafrost and the gas hydrates stability zone. New data are reported for the Kara Sea region where the bottom sediment temperatures are influenced by warming effects from great Siberian rivers and the Atlantic currents. The data collected during marine expeditions in 2019–2022 are combined with results of earlier marine studies, drilling operations, and geophysical surveys in the Laptev and East Siberian seas, in order to identify major trends of in situ temperature and properties distribution of bottom sediments in the Russian Arctic region.Most (85%) of bottom sediments in the Kara Sea shelf, as well as in the Laptev and East Siberian shelves, consist of water-saturated silty clay and silt with rather uniform particle size distribution. The obtained thermal conductivity and heat capacity values for the Kara Sea sediments agree with the values of 1.0 W/(m·K) and 2900 kJ/m3, respectively, obtained previously from other Arctic seas. Thermal conductivity becomes up to 40% higher depthward from 0 to 2 m subbottom depth, possibly, because of lower moisture content and porosity in more lithified sediments.The bottom sediment temperatures in the Arctic seas are distributed unevenly, especially in the Kara Sea shelf (from +5.0 °C in the west to −1.4 °C in the east), where the high sediment temperatures in the western and central parts of the Kara Sea being due to the effect of warm water inputs. The distribution of bottom sediment temperatures correlates well with distribution of relic subsea permafrost. Ice-bearing permafrost in the Siberian Arctic shelf extends from the shoreline till sea depths of 80–100 m, within the respective offshore distances of ∼800–1000 km in some areas, but permafrost remnants may exist locally at sea depths within 120 m. Buried 100–600 m thick continuous subsea permafrost may occur in the Kara, Laptev, and East Siberian shelves under unfrozen (cryotic) saline shallow sediments. However, subsea permafrost is discontinuous and sporadic at sea depths ∼70 m and more. Thus, the bottom sediment temperature features in the Arctic seas can be used as a proxy of subsea permafrost extent contenting intrapermafrost and subpermafrost gas and gas hydrate accumulations.

About the application of modern geophysical research methods and the problems solved Summary

The vast majority of oil and gas fields in Azerbaijan are at the final (late) stage of development, and therefore a natural decline in production is expected. Despite the long-term development of fields, their reserves are of great industrial importance for ensuring the stability of the energy balance of our country. Therefore, it became necessary to introduce new technologies in order to maintain or partially increase production at fields that are in long-term development. Before carrying out geological activities, it is necessary to apply a new type of more modern borehole geophysical research in order to involve in the processing of zones with residual resources of these depleted fields. From this point of view, the article considers the application and results of modern borehole geophysical surveys, and analyzes the possibilities for expansion.

Geophysical survey at the frontier of medieval Iberia: The castles of Molina de Aragón and Atienza (Guadalajara, Spain)

AbstractThis paper presents the results of geophysical surveys conducted within two castles in central Iberia: the fortifications of Molina de Aragón and Atienza, both located within the modern province of Guadalajara in Spain. They represent essential case studies for understanding the transformations of the frontier societies of medieval south‐western Europe, because both were founded during the Andalusi period, both played a fundamental role at the time of the military confrontations between opposing Islamic and Christian states, and both became capitals within the feudal dependencies of the Crown of Castile during the Late Middle Ages. At present, these castles are uninhabited and protected archaeological sites, with no modern developments within their wards; the adjacent towns have developed on the outskirts of their outer walls. Although both castles have been the focus of uneven amounts of archaeological research, geophysical surveys, the first conducted at these sites, have proved to be a fundamental tool not only for planning future archaeological investigations but also for the data that they have provided on the potential roles of these castle wards.

Application of the Magnetic Geophysical Method to Exploration of the Potassic Zone in Some Porphyry Copper Deposits (Iran)

Haftcheshmeh, Masjeddaghi and Nowchun are three giant porphyry systems located in Iran. Because of the presence of potassic alteration outcrops in the Haftcheshmeh ore deposit (NW Iran), we decided to detect borders of this alteration zone by a ground magnetic method. Goal of exploration is to understand the distribution of concentration in porphyry systems, as the level of magnetization commonly differs across alteration boundaries. Further, 3D interpretation of magnetic data is important to improve our understanding of geology and alteration in the system. In this paper, qualitative and quantitative results of geophysical surveys are presented in the form of total field intensity, second derivative, upward continuation and pole reduction maps. Comparison of magnetic results with borehole logging provides a good pattern to a field geologist to assign and guide an exploration project. According to this pattern, all drill holes in Haftcheshmeh, Masjeddaghi and nowchun porphyry system were designed. According to the results for the mentioned copper systems, anomalous magnetic features are related to the sub-volcanic intrusions and high anomaly zones over the potassic alteration probably show the existence of magnetite. The potassic zone pattern can be used as a key in all further exploration of porphyry systems.

Origin and Forming of Hacham Island in Khor Al-Zubair Channel, Southern Iraq

The marine geophysical survey was conducted using Sub Bottom Profiler and Side Scan Sonar techniques, integrated by petrographic analyses including grain size distribution, mineralogical and fauna analyses of the Hacham island and surrounding area. The island is located in the south part of the Khor Al Zubair channel southwest of the Basrah, Southern Iraq. The study aims to determine the origin and stages of the island formation. This study concluded that there is more than one factor that contributes forming this island represented by tectonic, morphological and sedimentological factors. The results of marine geophysical surveys revealed that the island and its surroundings were affected by the neotectonic activity that exposed the lower part of the Mesopotamian Basin, which in turn caused the lower part of the Khor Al-Zubair channel to meander eastward because of its impact by the fault that separated Warbah island from the Iraqi coast, forming Khor Shaitanah. The meandering of the Khor Al-Zubair course was accompanied by a decrease in flow velocity and thus a decrease in the channel’s ability to carry more sediments, therefore the Khor has to take another course, this waterway separated the island from the main east Iraqi coast. The results of the grain size distribution, mineral identification and fauna analyses indicated a variety of sediment supplying sources of the island, represented by the floods deposits of rivers and side drifts of the surrounding area, in addition to the aeolian deposits transported from the west and northwest Dibdibba Formation. The present study also concluded that the central East shore part of the island is exposed to erosion as a result of a submerged wreck in the waterway that separates the island from the coast.

Noble gases in shallow aquifers preserve signatures of boiling events beneath Weishan volcano of Wudalianchi volcanic field, northeast China

The study on whether there is a magma chamber under Wudalianchi is a hot topic recently, as it holds great significances for the theory of plate tectonics, early warning of volcano eruption and geothermal exploration. There is no near surface geothermal abnormality reported in Weishan, the widely used and well-studied tool, geochemistry of geothermal fluids and geothermal gases, cannot be applied to this area. To reveal the thermal conditions under Weishan, we conducted a study about the abundances and isotope ratios of dissolved noble gases in shallow groundwater and springs of Weishan. The concentrations of noble gases display obvious Ne excesses and mass-dependent differentiation, the isotopic ratios indicate that Ne, Ar, Kr, and Xe are atmosphere-derived noble gases (ANGs). We apply the closed-system equilibrium (CE) model to process the data of noble gases, and indicate that the excess ANGs are not caused by the increased hydrostatic pressure or diffusive influx. Neither meltwater mixing nor oxygen consumption alone could generate sufficient noble gas excesses in our samples. Based on the reconstructed abundances of noble gases in vapor phases produced at different boiling temperatures, which are calculated according to the boiling model established on Henry's law, we conclude that the abundances of noble gases in these samples were influenced by vapor–liquid partition caused by underground boiling. The diagrams of 84Kr/36Ar, 20Ne/36Ar and 130Xe/36Ar confine the temperature range where the boiling events occur in ∼100 °C–300 °C. We argued that the excess ANGs in shallow groundwater are geochemical evidence of boiling events, which seems to be continuously happening during the time range confined by the young groundwater in basalt aquifer and old groundwater in sandstone aquifer. Our findings also corroborate the recent results of geophysical survey works that a potential magma chamber exists under Weishan area. We suggest that noble gases dissolved in shallow aquifers represent a reliable geochemical tool to unveil subsurface geothermal state, where no near-surface thermal anomaly occurs.

Paleomagnetic-Geodynamic Mapping of the Transition Zone from Ocean to the Continent: A Review

The easternmost Mediterranean is a distinct transition zone from the ocean to the continent located at the junction between the largest Earth’s lithospheric segments: Eurasian and African. The methodology of paleomagnetic mapping of such transition zones is based on integrating the mapping techniques for both continental and oceanic platforms: paleomagnetic reconstructions, results of radiometric dating of magnetized rocks, tectonic-structural reconstructions, biogeography, and utilization of the results of various geophysical surveys. The geodynamic-paleomagnetic mapping makes it possible to reveal the multilevel structural heterogeneity and display complex elements of the geodynamics of different ages inherent in this transition zone. The region of northern Israel is the most complex area in the easternmost Mediterranean. For the combined paleomagnetic mapping, well-studied paleomagnetically and radiometrically areas were selected: (1) the Carmel area, (2) the Atlit area (internal part of the Carmel area), (3) the Sea of Galilee with the adjoining zones (primarily, the Kinnarot Valley), and (4) the area of the Hula Basin with adjacent areas of the Golan Plateau, Hermon Mt., and Galilea uplift. The constructed paleomagnetic profiles for the Carmel area (on the top of the accumulative surface of the Lower Cretaceous traps) and the Kinnarot Valley—Sea of Galilee—Hula Basin, evidently indicate the complex history of the paleogeodynamic evolution of the region. These studies demonstrate the effectiveness of paleomagnetic mapping integrated with paleomagnetic profiles crossing these geologically complex areas.

Comparative study of gravimetric and well data in Khidirli-Bendovan structures

The discovery of new oil and gas deposits depends on the right drilling direction, which, in its turn, is associated with the results of geophysical surveys and their appropriate estimation. In this view, a comparative analysis of the results for the wells drilled in Khidirli-Bendovan structures with up-to-date gravimetric data (performed via high accurate “Scintrex-CG-5 Autograv” device of Canada) has been carried out and can play a significant role in the selection of appropriate location of the wells to be drilled in the future with the purpose of discovery onshore oil and gas deposits in Azerbaijan.

Ways to improve the reliability of interpreting the results of geophysical surveys performed for the local forecast and prospecting for solid minerals: a geodynamic approach

Background. The geodynamic approach is effectively used in regional forecasting and prospecting works. However, its application for local forecasting and prospecting for solid minerals is limited and sometimes impossible. One of the key problems of local forecasting and prospecting for minerals (solid, liquid, gaseous) is the presence of non-standard (flickering) geophysical anomalies, which complicates the interpretation of the results of geophysical surveys performed at different times at different stages of geological exploration. The article is devoted to clarifying the possibility of using geodynamic research in local forecasting and prospecting for solid minerals on the basis of attracting the latest scientific knowledge from the field of studying the spatio-temporal patterns of the development of modern geodynamic processes and their influence on the Earth’s geophysical fields. Aim. To increase the reliability of interpreting the results of geophysical surveys performed for local forecasting and prospecting for solid minerals.Materials and methods. The research was carried out on the basis of a comprehensive analysis of literature data, fund materials and the results of many years of the author’s own research in the fields of modern geodynamics and prospecting and exploration geodynamics. The initial data were based on the monitoring data of various Earth’s geophysical fields (deformation, seismic, and surface magnetic).Results. A geodynamic reason for the appearance of flickering anomalies in the Earth’s geophysical fields (in particular, magnetic) has been established, and a mechanism for their formation under the influence of modern geodynamic processes has been proposed. The possibility of using the geodynamic approach in the prospecting for solid minerals has been expanded, and ways to increasing the efficiency of local searches have been proposed.Conclusions. The research demonstrates the possibility of using geodynamic studies in local prospecting for solid minerals, which helps to increase the reliability of the results of interpretation of geophysical survey data, and, as a result, to reduce the overall financial and time costs involved with searching for mineral deposits.

Some features of prospecting work in the oil and gas region of Ganja

Extensive exploratory investigations and borehole surveys have confirmed the high prospect of oil and gas potential of the Upper Cretaceous-Maikop deposits in numerous structures in the Ganja oil and gas region. The structures identified in the OGR have a complex structure and are also complicated by multidirectional fractures. Although the regularity of field formation has been clarified, an individual approach to prospecting and exploration operations at each block is necessary. It is necessary to direct prospecting and exploration operations to obtain direct geophysical parameters representing oil and gas potential in other blocks, taking into account the results of recent comprehensive geophysical surveys at the Gazanbulag-Chaily and Naftalan-Godakboz fields. Taking into account the available geophysical data and using appropriate geophysical complexes for predicting of oil and gas potential in anticlinal and non-anticlinal structures, determination of their boundaries and depths, elements of traps and stratigraphic affiliation is an effective way for further exploration of oil and gas.
