Remediation of the subsurface contaminated with petroleum products is the ecological problem on a world scale and a foreground direction of geoecological research in Ukraine. Remediation of contaminated vadose zone can be provided with the activity of microorganisms, mainly micromycets, whose features of location and vital activity depend on a depth, the level of contamination, aerobic conditions, etc. Practically, it is complicated to use artificial microbiological methods and natural remediation of contaminated subsurface due to microorganisms should be taken into consideration. Microorganisms oxidizing hydrocarbons are of particular interest. Field investigations were carried out within the fuel storage of the Boryspil airport where subsurface contamination with petroleum products was revealed in 1998. The research included sampling at contaminated and uncontaminated sites, quality analysis of petroleum product contains in soils and determination of the species composition of micromycets. Soil samples were taken in three wells at different depths – in the center of the contamination source at the depths of 0,1 m and 2,0 m (unsaturated zone) and 4,0 m (saturated zone), in the northern part of the fuel storage in the unsaturated zone at the depths of 0,1 m and 1,0 m, and out of the contamination source in the unsaturated zone at the depth of 3,7 m. Fungus culture determination data in soil samples indicate that variety of their forms depends on a contamination degree, a depth of sampling, lithology and water saturation. Regular monitoring should be carried out including soil sampling and determination of petroleum product contains to specify conclusions about natural remediation of contaminated soils due to life activity of microorganisms oxidizing hydrocarbons.

The main source of germanium sequestration in Ukraine is coal. According to modern requirements, the content of germanium in coal should be more than 10 g/t (air-dry weight), in coking - 3 g/t. Germanium can be obtained from mine water and coal rocks, as well. In Ukraine, germanium carbonate rocks are distributed in the sediments of the Lviv-Volyn and Donetsk basins. The distribution of germanium in the rocks of coal basins is different and rarely obeys laws. All coal layers tested are more or less germanium. Tectonic disturbances had no controlling effect on the accumulation and spread of germanium in the coal basin. The highest content of germanium is found in the central and western parts of the Donetsk coal basin district. The search and reconnaissance work on germanium has been widely disseminated since 1954. The work was carried out at various mineral deposits in order to identify raw materials for the related extraction of germanium. The degree of study and industrial development of these areas are different. The content of germanium in the coal of different layers varies in a wide range. Germanium is used in many industries and demand for it is constantly increasing. The scope of the metal is quite wide; it is used for the manufacture of transistors and circuits, for engineering and electronics. Radar installations use thin germanium films that are pre-applied to the glass substrate. The subsequent withdrawal of germanium is one way to improve the economic performance of the coal industry. Concomitant extraction of germanium from coal, products of its processing and mine waters of Donbass is now quite realistic and can help to increase the profitability of coal enterprises.

The stratigraphic scheme of the Early Precambrian of the Ukrainian Shield bears a number of differences from the traditional regional stratigraphic schemes: 1) along with stratified subdivisions it includes intrusive and ultrametamorphic complexes that are not accounted for in the “Stratigraphic Code of Ukraine”; 2) The leading role in creating the regional stratigraphic scheme was played by isotopic dating results; 3) The Stratigraphic Scheme does not include the taxon “complex”, as it is described in the “Stratigraphic Code of Ukraine”. According to “Stratigraphic Code of Ukraine”, “Complex” is the largest regional stratigraphic unit that corresponds to a large geo-historical period. Due to the absence of the taxon of “complex” in the regional Precambrian stratigraphic scheme, the main stages of geological development of the region in the Precambrian have not been identified for the Ukrainian Shield. The first article of the cycle is devoted to the feasibility of introducing the taxon of “complex” in the regional stratigraphic scheme on the materials of the Ukrainian Shield. It notes that most of the series in the current stratigraphic scheme correspond to complexes by their level of study and their historical and geological content. Such units are Konkska, Kryvorizka, Teterivska, Ingulo-Inguletska and some other series. Each of them can be separated into several series. The Dniestrovsko-Bugska and Bugska series, the West-Priazovska and Central-Priazovska series of granulite-gneiss complexes are artificially separated and shown as different age subdivisions in the current stratigraphic scheme. These series should be included in the Bug Area and Azov Area complexes, but their volumes and names need clarification. Amphibolite-gneiss complexes can be included in the stratigraphic scheme without dismemberment into series, since they correspond to a large geohistoric stage marked by the peculiarities of their material composition and structural-tectonic position.

Results of complex research of different age ancient weathering crusts in various rocks (terrigenous-carbonate rocks of Lower Paleozoic, dolerites, tuffs and tufogene formations, kimberlites) within the main diamondiferous regions of the Siberian platform indicated that complicated multicomponent composition of initial formations (with the exception of terrigenous-carbonate rocks), containing di- and trioctahedral minerals, the structure of which has tri- and bivalent rock-forming elements, stipulated decelerated transformation of the initial material. Development of incomplete weathering profiles is first of all caused by weak ejection of bivalent cations from primary minerals. That is why newly emerging phases will be dioctahedral and often preserve mixed composition of cations. The most important typomorphic indications of clay formations in the studied weathering crusts are as follows: a) omnipresent dioctahedral hydromica (2М1) in the weathering crust of terrigenouscarbonate rocks and its association in the most mature profiles with kaolinite of relatively ordered structure, than of kaolinite, having been formed at the expense of other rocks; b) constant availability of trappean formation (tuffs, tufogene rocks, dolerites) in sections of crusts of weathering together with di- and trioctahedral montmorillonite, as well as disordered vermiculite-montmorillonite mixed-layered formation, to this or that degree disordered kaolinite, associated in the weathering crust of tufogene rocks with halloysite (at complete absence of micaceous minerals in the products of weathering); c) the content in the crust of weathering of kimberlites together with polycationic montmorillonite of a significant quantity of trioctahedral chlorite (packets δ and δ'), serpentine (structural types A and B) and altered to various degree phlogopite, including related with it hydromica 1M.

The mineral base of iron ores is characterized by intensive use and includes explored and pre-explored reserves, most of which belong to a distributed subsurface fund. The objects of accounting (deposits) are grouped according to the size of stocks and on the basis of involvement in industrial development. The allocated groups of deposits, for which the volumes of reserves are set, make up 100 million tons, 100–500 million tons, 500–1000 million tons. and more than 1000 million tons. The grouping of reserves of iron ore deposits by size allows us to state that about 80 % of the reserves of iron ores for the developed deposits are provided with reserves of 500 million tons. and more, which confirms the average level of their exhaustion. The degree of provision of iron ore reserves according to the existing special permits for the use of subsoil and project output for production was introduced. Groups of fields for which the terms are set are up to 30 years, 30–50 years, 50–100 years and over 100 years. It has been determined that financing of exploration works (GAR) for iron ores in the framework of the current National Program for the Development of the Mineral Base of Ukraine until 2030 is provided exclusively at state cost and non-state funding is not taken into account. In order to identify the optimal distribution of financing for exploration works by stages, comparison of funding rates under the Program up to 2030 with the distribution of the main geological risks and general risks of mining business has been made. At the stage of search and search-and-appraisal, a high level of geological risks of 50 % and mining risks in 70 % is accompanied by public funding for iron ore and reaches a critical value of 80 % with a similar indicator for the entire program at 65,7 %. The level of financing of the III stage of exploration for iron ore accounts for 20 % of the total volume, with a rather low level of geological risks of 10 % and mining risks at 10 %, respectively.

Features of structural conditions of occurrence, gas accumulation, lithofacies, petrophysical and geochemical parameters, shielding factor, character-bearing shale gas saturation are fundamentally different from traditional gas deposits. Stratigraphic shale formation considered as a potential gas deposit. Considering this specificity its allocation and mapping must be executed at an early stage. To delineate gas bearing shale formations of Volyno-Podillia and allocation the most perspective areas offered a complexation of regional seismic survey 2D for great depths (two longitudal profiles of north-western stretch as it continued from the Lublin basin in Poland and 5 crosssections from southwest to the northeast with its total length of about 1500 linear kilometers) with electric prospecting methods of different modifications, caused polarization, electromagnetic methods of regional seismic exploration grids profiles, large-scale atmogeochemical shooting and other direct methods. As the completion of regional stage must be drilling of vertical parametric pilot wells with solid coring from perspective shale strata, laboratory studies of organic matter, of katagenesis, lithofacies and mineralogical composition of shales, their petrophysical and geochemical properties, modeling and testing perspective shale strata using multistage hydrogaps.

Stratigraphic shale formation considered as a potential gas deposit. Considering this specificity its allocation and mapping must be executed at an early stage. To delineate gas bearing shale formations of Volyno-Podillia and allocation the most perspective areas offered a complexation of regional seismic survey 2D for great depths (two longitudal profiles of north-western stretch as it continued from the Lublin basin in Poland and 5 crosssections from southwest to the northeast with its total length of about 1500 linear kilometers) with electric prospecting methods of different modifications, caused polarization, electromagnetic methods of regional seismic exploration grids profiles, large-scale atmogeochemical shooting and other direct methods. As the completion of regional stage must be drilling of vertical parametric pilot wells with solid coring from perspective shale strata, laboratory studies of organic matter, of katagenesis, lithofacies and mineralogical composition of shales, their petrophysical and geochemical properties, modeling and testing perspective shale strata using multistage hydrogaps.

The article describes the approaches to the implementation of hydrogeological zoning of Ukraine according to the structural-hydrogeological principle. In accordance with modern geostructural zoning in the Ukraine, the authors identified 10 hydrogeological regions of the first order. Each of the identified regions is characterized by its own peculiarities of the geological and hydrogeological structure, and as well as regional peculiarities of hydrogeological conditions. These patterns determine the conditions for the formation and distribution of the predicted groundwater resources and their quality indicators. The features of Ukraine’s hydrogeological regions of the first order are briefly characterized.
