The area of the Pologivskiy deposit of kaolins and refractory clays is located on the border of two geological regions: the Azov crystalline massif and the Konksko-Yalynska depression. Precambrian crystalline rocks and sediments of the Cretaceous, Paleogene, Neogene, and Quaternary systems take part in the geological structure of the district. The geological structure of the district is based on the results of field exploration (23–25) and geological surveying works. Deposits of the Quaternary system are widespread in the territory and are similar to mantle on the underlying rocks. The lower border of the Quaternary system is formed at the base of the Berezanskiy climatolite in accordance with the Geological Map of Ukraine legend (the scale 1:200 000) of the 1996 Central Ukrainian series. The underlying rocks are red-brown Pliocene clays in most parts of the territory, in the rest there are rocks of crystalline basement of Cretaceous, Paleogene and Neogene systems. The thickness of the Quaternary deposits is 10–20 m. Deposits of the Novopetrivska Neogene suite are productive for the extraction of clays and kaolins, in the base of which the undivided deposits of the Upper Eocene (Kyivska suite) and Oligocene (Kharkivska suite) lie. These are coastal-marine deposits – marls, calcareous clays, siltstones, weakly cemented sandstones and glauconite quartz sands. The total thickness of the Kyivska and Kharkivska suites varies from 0,0 to 60–70 m. Clays and kaolins are characterized by almost the same mineral composition. Most of them are composed of fine-grained kaolinite, and quartz predominates among impurities. Accessory and ore minerals are represented by zircon, rutile, ilmenite and hematite. Quartz is present in clays and kaolins in the form of rolled, semirolled and unrolled grains. High-quality aluminosilicate products are obtained from the kaolins of the deposit. Pologivskiy kaolin can be used to make chamotte without the clay addition, as well as a binder. The ratio of chamotte and binder is 80–20 %. The refractories obtained in the laboratory meet the requirements of high density for Class A blast furnace bricks and other products of appropriate determination. Pologivskiy clays are recognized as suitable for the production of 100 % refractories, as well as a binder component instead of ChasovYarska clays. Products made entirely of semi-acid clay meet the requirements for semi-acid refractory products of class B. Pologivskiy kaolins and clays have long been used in refractory, machine-building, ceramic, cement and other industries.

Steppe landscapes, which are within Ukraine, over the last few centuries has undergone significant negative changes due to the unreasonable use of soil resources (excessive ploughing), soil salinity under irrigation in agriculture and other forms of anthropogenic impact. The territory of modern Zaporizhzhya region, which belongs to steppe landscapes, as a result of human activities is also dramatically changed. For the further organization of the rational environmental management, first of all, it is necessary to provide scientific-based recommendations for the reduction of anthropogenic human impact on the landscapes of the region. Nowadays, this is a topical and very important issue, but without a perfect research algorithm, the solution of the question is impossible. The main methods of studying the anthropogenic impact and the state of regional nature management have been considered in the article. On the basis of existing methods and rules the four main stages of the study have been identified and the algorithm that reflects the sequence and conditionality of the procedure for anthropogenic impact on the landscapes of Zaporizhzhya region has been developed. At the first stage, collection and systematization of the available information with a corresponding set of actions, including field studies, took place. At the second stage, the theoretical and methodological base of the research was formulated – from the generalization of theoretical foundations of the research, the definition of the object and subject, the analysis of the current state of the study of the issue to the development of its own solution of the scientific issue. The third stage envisaged the study of the structure features and functioning of the landscapes of Zaporizhzhya region – from the analysis of natural and anthropogenic factors of the formation of modern landscape structure, the specific features of natural conditions and resources, the anthropogenization processes to the analysis of the actual structure and peculiarities of natural and anthropogenic landscapes functioning. At the fourth stage, the current state of regional environmental management of Zaporizhzhya region has been analyzed, the features of the manifestation of unfavourable natural means, as well as the analysis of the dependence of their manifestation on the level of anthropogenic transformation, have been revealed. The author’s suggestions as to the organization of rational environmental management in the region and the basis of the management system of the landscape have been formulated through the procedure of accurate accomplishment of its stages such as planning, design, implementation and control.
