On the basis of the analysis of the literature sources, we determined the possible range of using the method of the Earth`s natural pulse electromagnetic field. As a result of detailed analysis of domestic and foreign research, we demonstrated the relevance of conducting research focused on development of the Earth'snatural pulse electromagneticfield (or ENPEMF). Using the results of theoretical studies, the advantages and disadvantages of the ENPEMF method were determined. A complex of physical processes which preceded the development of the pulse electromagnetic field of the Earth was characterized, and the impact of mechanical deformations of rocks on the change in the condition of the electromagnetic field was experimentally proven. The main fundamentals on the determination of depth range of the ENPEMF method were examined and a new approach to interpretation of the data was suggested. We conducted an analysis of methods developed earlier of calculating geometric parameters of the sources which generate electromagnetic impulses. Their practicability at a certain stage of solving the data of geological tasks was experimentally tested. We determined the factors which affect the depth range of the ENPEMF method. A mathematical solution of the effectiveness of the ENPEMF method was suggested and determined the relations between the depth parameter of the study and the frequency of measuring and effective value of specific electric resistance. On the example of different objects, the effectiveness and correctness of the suggested method of determining the depth range parameter was proven. In particular, the theoretical results of the study were tested and confirmed on objects of different geological-morphological and engineering-technical aspects, i.e. Novo-Holyn mine in the Kalush-Holynske potash deposit and the multi-storey educational building of the University in Ivano-Frankivsk. The practicability of using the ENPEMF method in combination with other methods of electrometry for solving practical geological tasks was experimentally proven.
The purpose of the article is to carry out a complex analysis of conditions and natural factors forming the hydrogeological regime as well as to integrate the existing information and groundwater monitoring data in Ivano-Frankivsk region for further creating the unified automated system to collect, process, analyze and store the monitoring observation data. The authors offer methodology, which is based on the geoinformation approach, for organizing and monitoring of the groundwater. The structure of spatial and attributive data that afford to systemize the existing schemes of the hydrogeological zoning as well as the results of long-term observations over variability of the groundwater levels and factors forming the hydrogeological regime were developed. The new approaches for improving the techniques to forecast the groundwater level with due consideration of temporal patterns for changes in water level, the Moon phases and seismic activity, are proposed. The obtained results are considered as an informational basis for reorganization of the state hydrogeological monitoring on the example of Ivano-Frankivsk region.
Abstract:In order to restart the state hydrogeological network and adhere it to European standards in the shortest possible terms, the following top-priority tasks shall be performed: an inventory of the observation stations, assessment of their representativeness, development of the concept for the monitoring system reformation, as well as creation of a single database with GIS-technologies. To solve the abovementioned tasks, we have carried out a geoinformation analyses concerning the locations of ground water monitoring stations within the largest hydrogeological structure in Ukraine (which is the water exchange basin of the Dnieper River). In the course of the study, a geodatabase has been created that includes digital cartographic layers of the topographic base, hydrogeological zoning under the geological structural, and water exchange principals as well as the surface and groundwater monitoring stations of different aquifers.The obtained results establish the grounds for developing the concept and introduce a system of hydrogeological monitoring in Ukraine based on the geoinformation approach and integrated water resource management in the river basins.
The purpose of the work is to determine the state of study and the prospects for further research on the vertebrate animals remains from the Mesozoic deposits of the Lugansk region. To achieve this goal, collection and generalization of information on the locations of vertebral remains among the Mesozoic deposits of Lugansk region were made. Despite the considerable amount of findings of various groups of Mesozoic vertebrates remains in the Donets Basin territories adjoining them, their systematic and purposeful study, unfortunately, was not conducted in Lugansk region, although indications of the findings of the Mesozoic vertebrates remains in the Luhansk region occur quite often. As a result of the processing of published materials and preliminary interpretation of field observations, a list of 20 sites located mainly on the right bank of the Siversky Donets within the Lugansk region is compiled. Almost all the places are confined to the Upper Cretaceous deposits, much less – to the basal layers of the Paleogene and only one to the Triassic. The vast majority of the locations of the Upper Cretaceous are confined to the area in contact with an array of coal deposits (the so-called "open Carboniferous"). Outwards from it, the rocks are more open-sea and they drastically reduce the diversity of the fossil fauna. Therefore, outlining the range of promising areas regarding finding vertebrate animals remains one should be aware of the above-mentioned pattern of their placement. Triassic deposits of the Donbas are not at all investigated for finding the remains of vertebrates, although their potential is very significant. Nevertheless, due to the small area of the Triassic deposits outcrop in the Lugansk region, searches need to be directed to the west – in the Donetsk and Kharkiv regions.The problem of solving the ecological and geological issues which arise as the result of working off in natural resources (in particular the deposits of potassium salts) is actual at this time. Specificity is in easy solubility of salts and therefore the creation of artificial cavities and karstic phenomena. The article examines the ways to solve the problems of mapping the salt karst and forecasting creation of dips and subsidence of the earth's surface by the example of Kalush-Holyn potassium salt deposit which is located in Ukrainian Precarpathians. As the basis of the research, the complex geophysical methods were considered. It was proved that the method of natural pulsed electromagnetic field of the Earth (NPEMFE) can be selected as a reliable evaluation method of stress-strain state of rocks and prediction of karst processes and deformations which is associated with the presence of extracting chambers. The article describes the physical preconditions for applying the method, sets out the basic postulates of field intensity anomalies classification and proposes the methodology for depth evaluation. Using the real examples - the profile and planar research of potassium salt deposit - the succes of the NPEMFE method is shown, along with its effectiveness to solve some ecological and geological problems, as well as feasibility of using the method in other areas.
