**Magnetism of environmental objects in oil and gas promising fields in Western Ukraine***(A. Menshov, R. Kuderavets, I. Chobotok)*Existence of local magnetic anomalies with a few nT amplitudes upon oil and gas deposits proportionate with structure contours was approved in practice by magnetic measurements in different hydrocarbon structures and can be one of the searching criteria for hydrocarbon traps. Hydrocarbon migration and microseepage effect change composition of magnetic minerals including nearsurface areas and soils. The results of magnetic studies on Vizhomlya and Sudova-Vyshnya gas fields in the Ukrainian part of Carpathian Foredeep are shown. Specific features of structure of the local magnetic field and the magnetic susceptibility of soil are analyzed. The local magnetic anomalies with amplitude of 4–7 nT and a width of about 3 km were detected upon the investigated geological structures. Magnetic susceptibility investigations of soils on the Sudova-Vyshnya gas field showed close correlation with landscape changes. Soils are not very magnetic. The interpretation of the local magnetic and soil magnetic susceptibility anomalies upon hydrocarbon fields is a complex problem and needs further researching, including the integration of other geophysical methods in solving problems of petroleum geology.

**Deep structure and metallogeny Kirovograd ore district***(G.M. Drogitska)*The present study demonstrates spatial links between surface structures of the polymetal Kirovograd ore district and the middle-scale heterogeneity of crust and crust-mantle boundary. The architecture of the Kirovograd ore district is dominated by the Novoukrainsk-Korsun’-Novomirgorod pluton. The localization of uranium, lithium, gold deposits in the Novoukrainsk-Kirovograd granitoid massif is determined by the existence of a deep-seated mantle trough, which is going across the pluton. Based on the accumulated data we regard the Kirovograd ore district as a Paleoproterozoic center of mantle-crustal magmatism and endogenous ore formation.

**Stable solutions of inverse problems of gravity-magnetometry on shilds***(P.O. Minenko, R.V. Minenko, Yu.P. Mechnikov)*The results of the solutions of inverse problems with different ratios of the area map of the field to the area of interpretation model. It was found that the equality of these areas have the highest stability of the solutions. The field is recovered almost completely with very small standard deviation and its very low balances at any point after the solution of the inverse problem. For any excess of this ratio, especially in the two or more times, the inverse result distorted, appear on large area anomalies of one sign that can not be explained distribution of the field. Despite certain difficulties, to get some quantitative and spatial validation of the interpretation of the magnetic field geological data after drilling wells in geological sections, the structure of the iron ore deposit crosses. Dedicated area of high magnetization ferruginous rocks, which according to the drilling layers correspond with the highest iron content of magnetite. In general, the structure and location of the magnetization oscillations in it reliably established, contour magnetization traced over large areas. Set the border zone of oxidized ferruginous rocks, which coincides almost exactly with the border, dedicated to geological data. Failure to observe the ratio of the areas of the field maps and interpretation model leads to instability of the solutions of the inverse problem with the violation of the actual distribution of the magnetization in the layers of maps and vertical sections of the magnetization of rocks.

**The linear interpolation on triangulated region as a method of 2D parameters modelling in the case of a priori information absence***(I.P. Dolinsky, O.P. Lobasov, V.M. Ogarkov)*The paper is devoted to developing the method of iterative linear interpolation on triangulated region for building of 2D parameters models in the conditions of data insufficiency and irregularity without a priory information. The approbation results using synthetic and real geological data are shown. In the regions of rare data the method, reveal more adequate structural model in comparison with other interpolation methods. The synthetic model example shows that result doesn’t depend on the mean of triangulation. The model doesn’t gain the properties that are not absent in intial data and rule out the border effects. The modelling of parameters that naturally rule out thinning (layer pressure and temperature, mineralization, chemical components of rocks and bed fluids etc.) is the sphere of use the method in the first place.

**Assessment of the corrosion processes impacton the pipeline natural-technical systems by the electrical methods***(R.N. Hloba, E.M. Ivanik, Ya.N. Hloba, S.A. Vyzhva)*Physical, physics-chemical and chemical types of influence are defined as a result of the impact of geological environment on the pipeline system. Corrosion is significant physical and chemical process that affect on the functioning of the pipeline transporting systems. Successful protection of pipeline systems may be effected at timely detection of corrosion damage, determining of its size and choice of protective measures. Geophysical investigations are the most important among the various methods that used to identify areas of corrosion. Electrical geophysical investigations are most informative among the optimal methods to determine the corrosion activity of soils. Electrical methods, such as vertical electrical sounding, symmetrical electrical profiling, gradient potential method and self-potential method were used to identify possible areas of corrosion on the underground pipeline of filling station “Kiev-4”. The low apparent resistivity and high negative spontaneous potential values are indicated that the soil is very corrosive and there is the possibility of the pipeline failure in the future. Electrical geophysical investigations along buried pipelines should be undertaken for the early detection and prevention of pipeline failure with its negative environmental and economic consequences.

**Model truncated distribution of content hydrochemical data***(A. Klypa, M. Zhukov)*The object of the study was modeling distributions of trace elements in natural waters based on the truncated normal and lognormal distribution. To accomplish this goal was necessary to develop a method for estimating the parameters of both models and implement it for hydrochemical data processing. The method makes possible to extrapolate the density distribution curve in the left side of the cutoff point based on evaluation of the available parameters observations on the right side. Extrapolation in the left side of the cutoff point has been done based on symmetric method, method of the least squares and method of Kolmogorov. As a result, the method for estimating the parameters of both models was developed and implemented for hydrochemical data. The use of these models to handle hydrochemical data helped to solve metrological problem associated with insufficient sensitivity of measuring device. Proved that the truncated distribution models gives accurate estimates of numerical characteristics of distributions as a result integral characteristics of the ecological state of water bodies are more accurate. The software module provides a stable evaluation of function and density of distributions without distortion, which is usually practiced in similar situations. The method can be used to solve such problems in the study of other geological objects. The software module allows make all the necessary calculations in automatic mode.

**Modern peatlands formation modeling***(N.V. Vergelska)*Processes of modern peat deposition within the Ukrainian Shield and Dnieper-Donets basin as constituents of recent continental sedimentation as deeply inherited development of tectonic settings favorable for coal formation during the whole Phanerozoic history. The degree of organic matter transformation was estimated by macro- and microscopic petrographic studies and spectral analysis of turf samples. A possible impact of a hydrogen-hydrocarbon-bearing fluid on recent formation of peatlands is estimated upon results of residual gas content in the turf samples. It was revealed that during deposition and maturation of organic matter within the studied areas of peat-bog sedimentogenesis the processes of oxidation, humification, beginning of gelification and sorption of gases in the system involving organic matter (vegetation remains) – groundwater table – H-HC-bearing deep fluid are actively developed. A similarity of processes governing organic matter transformations in a turf-bearing layer in different peat-bog complexes and various structures of the same landscape zone is evidenced. Detail study of organic matter transformation in modern geological structures will facilitate recognition of new contributing elements and geological and geochemical peculiarities of coal and coal-hydrocarbon systems development. Geochemical studies of interaction within the deep fluid – organic matter system will expand the set of criteria to predict coal-hydrocarbon complex accumulations in the sedimentary column.
