The paper looks at the structural tectonic location of Kharkiv oblast, its geological and geomorphological structure, which form the underlying features of nature’s variety and beauty, the development of the Nature Reserve Lands (NRL) of the region, the rich potential of the region’s natural complexes and objects, which have conservation, scientific, aesthetic, recreational and other values. It is shown that Kharkiv oblast, despite having a smaller area under the NRL than most other oblasts of Ukraine, has in fact great prospects for expansion in this respect, and also for improving the structure of the qualitative and quantitative distribution of Nature Reserve Lands objects. We analyzed the results of implementing the programme of forming an ecological network for the oblast and we emphasize the integral connection of biological and geological diversity. The protection of both the biological and geological elements is the path to stable development. We determined the historical preconditions for the necessity of preserving both inanimate nature and wildlife, beginning with the establishment in 1910 of the Khortytske Society for Nature Protection, the first such organization in Russia, to Ukraine’s joining the European Association for the Conservation of the Geological Heritage (ProGEO) in 1997. We evaluated the existing potential of the objects of geological heritage, had they been included in the NRL, the level of protection would have been extended and improved. For the first time, we provide a listing of the geological monuments of Kharkiv oblast, taking maximum account of the results of a revision of research, which was conducted in 2003-2004; and further monitoring and research, which was conducted in different years by scientists of V. N. Karazin Kharkiv National University for compiling a list of the geological heritage of the region. We identified the objects of geological heritage which have lost their significance as valuable objects of geological heritage due to natural and technological factors and thus should be excluded from the register. We determined the most valuable geosites, worthy of being included in the General European Register of Geological Heritage according to the criteria developed for the international project GEOSITES.

Геологічна спадщина, як невід’ємний елемент природно-заповідного фонду Харківської області

Розглянуто особливості структурно-тектонічного положення Харківської області, геологічної і геоморфологічної будови, сукупністю яких визначені головні риси різноманіття і краси природи, формування природно-заповідного фонду (ПЗФ) регіону, зумовлений потужний потенціал природних комплексів і об’єктів, що мають особливі природоохоронну, наукову, естетичну, рекреаційну та інші цінності. Встановлено, що Харківська область попри те, що посідає передостаннє місце в Україні за питомою вагою площі ПЗФ, насправді має надзвичайно великі перспективи щодо суттєвого їх збільшення та вдосконалення структури якісного і кількісного розподілу об’єктів природно-заповідного фонду. Проаналізовано результати виконання програми формування екологічної мережі області та зазначено невід’ємність зв’язку біоі георізноманіття, охорона яких є шляхом до сталого розвитку. Визначені історичні передумови необхідності збереження неживої природи в Україні так само, як і живої, від створення у 1910 р. першого в Росії Хортицького товариства охорони природи до прийняття e 1997 р. України в члени Європейської асоціації зі збереження геологічної спадщини (ProGEO). Оцінений дійсний потенціал об’єктів геологічної спадщини, включення яких до ПЗФ області суттєво розширить і покращить рівень заповідання. Вперше надається узагальнений список геологічних пам’яток природи Харківської області з максимальним урахуванням результатів ревізійного обстеження, проведеного у 2003-2004 роках, подальшого моніторингу та досліджень різних років, здійснених науковцями Харківського національного університету ім. Каразіна і спрямованих на інвентаризацію геологічної спадщини регіону. Встановлено перелік геологічних пам’яток, які втратили своє значення, як цінні об’єкти геологічної спадщини через природні і техногенні чинники і мають бути виключені з перспективних реєстрів. Визначені найбільш ціні геосайти, гідні включення до загальноєвропейського реєстру геологічної спадщини у відповідності із критеріями, розробленими для міжнародного проекту ГЕОСАЙТИ.

Introduction. Kharkiv oblast is situated in the water shed of the Siverskyi Donets river and only in the south is its landscape formed by the nearest tributaries of rivers Orel and Samara. From a geomorphological perspective, the oblast is situated mainly within the Prydniprovska lowlands, partly in the Central Russian uplands (in the north) and Donetsk uplands (to the southeast). But despite the great potential of the natural complexes and objects, which have special nature conservation, scientific, aesthetic, recreational and other values, Kharkiv oblast has one of the lowest levels of nature protection in Ukraine. Only 2.35% of the oblast is under the protection of the Nature Reserve Fund (NRF), the second lowest proportion in Ukraine, being larger only than Vinnitsa Oblast (2.1%) (Nature Reserve Land of Kharkiv oblast, 2016). The protection of so called inanimate nature, which is understood as objects of geological heritage which are important components of the Nature Reserve Land, is no better than that of biologically valuable sites.

On 1.04.2015, Kharkiv oblast was considered to have 242 territories and objects of NRL with a total area of 74.15 thousand ha. Similarly to other Ukraine regions, Kharkiv oblast confirmed the "Programme of Forming the National Ecological Complex for 2002-2015", which included analyzing, improving and developing the Ukrainian law according to the recommendations of the European strategy of protecting biological and landscape diversity for formation of a European ecological complex as a single space system of European countries' territories with natural or partially altered landscapes (Manyuk Vad. & Manyuk Vol., 2010). Adopting the Law of Forming Ukraine's Ecological Complex in 2000 had fundamental significance for the development of relations within society for preserving, restoring, protecting the single territorial functional system of territories with natural landscapes, protection of biological and geological diversity and for stable development (Manyuk, 2003).

The necessity of preserving the geological component of the NRF in Ukraine has deep historical roots - from 1910, after the establishment of the Khortytsa Society of Nature Protection, the first such society in pre-revolutionary Russia, to 1991 after the foundation of the European Association for the Conservation of the Geological Heritage (ProGEO). After its establishment in Europe, nature protection communities all over the world began to place geological diversity on an equal footing with biological diversity (Manyuk, 2005, 2006). The ruination or destruction of rare rocks and mineral

outcrops, remains of fossil fauna and flora, manifestations of glacial activity, signs of volcanism, or other evidences of the history of geological development, will lead to the irreversible disappearance of unique objects which took millions and billions of years to develop, but which can be destroyed instantly. Trees can be replaced with new ones, but geological objects cannot be renewed, therefore they become lost to humanity forever (Manyuk, 2007, 2014).

Presentation of the general material. The geostructural location of Kharkiv oblast provides good prospects for discovering and protecting the objects of geological heritage. The territory of the oblast is situated within the juncture of the Dnieper-Donetsk depression with the Donetsk fold structure in the southeast and the Voronej anteclise in the north. Therefore, its structure is developed by a complicated complex of deposits in a wide stratigraphic range (Gurskyi & Kalinin, 2011). The Precambrian rocks and Paleozoic rocks lie deep, but due to salt tectonics within Petrivskyi and Krasnooskolskyi diapirs, terrigenous coal outcrops of Devonian and bituminous coal systems appear on the surface. An important role in developing the geological structure of the region was played by the Mesozoic and Cainozoic deposits, which now have more than one outcrop. They are an important part of the natural and artificial outcrops (Fig. 1).

Fig. 1 Pre-Mesozoic map.

But this is only the potential, i.e. the variety of potential objects of natural geological heritage which have never been included in the official register of natural heritage. Currently Kharkiv oblast has only one object of geological heritage included in the NRL - the Protopopivskyi Geological Reserve of Local Significance. The resolution of the Rada (Council) of Kharkiv oblast of 17.11.1998 provided protection for an area of 14.6 ha which has protected natural outcrops of carbonate rocks of the Middle and Upper Jurassic, exposed by the Ploska Vodiana ravine and a small quarry in Protopopivka village (Leonenko, Stetsenko, and Wozniak (2003). The excellent paleontological quality of the limestone of the Izium and Donetsk Jurassic rock formations (Callovian, Oxfordian and Kimmeridgean stages), corals, brachiopods, Echinoidea and other fossil fauna allows one to consider this reserve a paleontological natural relic of stratigraphic value (Kosmachova, 2008).

According to the results of the revision of research of geological monuments (geosites) of Ukraine, which the author conducted in 2003-2004 as a part of the project of the State Geological Service of Ukraine, 23 geosites (including the Protopopivskyi reserve) were identified in Kharkiv oblast. The time limits of the study did not allow full evaluation of the oblasts geological heritage, therefore this list includes only 50 % of the geological monuments that are worth being protected. Using the results of the study, the 4 volume edition "Geological Heritage of Ukraine" in Ukrainian and English (Gurskyi & Kalinin, 2011) was published. The fourth volume covered 19 of the 23 studied geosites with correction of mistakes made during publication. The object «Zavodski Hutory» is mentioned in the book under numbers 11(incorrectly marked) and 19 (rock outcrops of Upper Jurassic limestone near the Dnipro-Donbass Canal). Everything is fine with its position on the map, but these are the abovementioned "Zavodski Hutory". It should be mentioned that unlike the objects situated on Ukrainian shield and which are represented correspondingly, mostly by hard crystalline Precambrian rocks, the geological monuments of Kharkiv oblast are mostly composed of loose sedimentary deposits, which are especially vulnerable to contemporary geological processes and have a short lifespan. Apart from the crumbling of fragments, landslides, blocking by dealluvial-proluvial sediments, erosional wash-out, the influence of technical loading, the process of clearing, excavating, and renewing a geosites is becoming impossible due to the growth of brushwood on the sections.

• Ilmenite placer deposit in the Romanovi Rovtsi tract near Nyjniy Bishkin village in Izium district.

• The location of silicified wood in Savyntsi urbantype village in Balaklava district.

• The outcrops of rocks of Beretska rock formation with osseous breccias in Kniazove tract between villages Nyjniy Bishkin and Suha Homolsha in Zmiiv district.

• The outcrops of Beretska and Mejyhirska rock formations in Kruhlyk ravine in the town Zmiiv.

• The outcrops of sandstones of the Kharkov geoseries in Kamyana Yaruha village in Chuhuyev district.

• The outcrops of Sarmatian layer rocks near Haydary village in Sahnowshyna district.

• The stepped fault on the slope of Monastyrska mountain in Haydary village in Zmiiv district.

• The Gotvald fault on the right bank of the Siverskyi Donets river near Zmiiv town.

• Section of Novoharkivska terrace in Buzynna ravine in Velyka Komyshuvata village in Barvynkivka district.

Out of 34 objects of natural heritage described in the guidebook "Geological Heritage of Ukraine" (Zaritskiy & Schyrytsia, (Eds.) 1985) including those that were recommended to be excluded and those which were included in the updated data base (Gurskyi & Kalinin, 2011), there are 9 more objects worth being included in NRL of Kharkiv oblast. The list of significant geological monuments can be enlarged by 8 important geosites included in the list, which were proposed by the leading researchers into the geological heritage of Kharkiv oblast, V I Kosmachov and M G Kosmachova, as monuments of national significance, and also the Chepilski Chalk Rocks and the Novomlynski Chalk Hills (Dvorichenski), which are not mentioned in any of the given sources, but which are becoming popular tourist routes (Lunyachek A. Encyclopedia of Travels. 2011). Therefore, Kharkiv oblast has only a single protected geological relic, but a number of potential geosites, which contains 40 objects of local and national value. Creating a unified register which would cover the full geological variety of Kharkiv oblast, bringing together information from scattered sources, requires providing a brief characteristic of the geological monuments of different categories and different types, obtained from the results of revised study and with the revisions mentioned above.

This is also necessary because the "Geosites" international project is not yet completed, therefore selection of geosites for the European list requires updated

and exhaustive information about the geological heritage of Ukraine (Wimbledon, 1997). The register is divided into three parts according to the possible category of conservation: local, national, and international value.

• Geosites of local level

◦ The outcrops of Sarmatian stage near Dar Nadiya village in Sahnowshina district. In a small quarry a section of loess alternation and fossils of Neopleistocene upper layers (7.5 m) and cross-bedding quartz sands of the middle Sarmatian substage (5.3 m) with carbonate and flint concretions have been excavated (Fig. 2).

◦ Hrekivske outcrop. On the left slope of the Hrekivka river, near its confluence with the Siversky Donets, there are outcrops of mottled clays of the Kimeridgian stage of the Upper Jurarrasic, oolitic limestones and limestone-coquina of the Callovian and Oxfordian stages of the Upper Jurarrasic, which are well characterized by the diversity of fossil fauna.

◦ Vovchanske outcrop of the Campanian and Maastrichtian stages chalk of the Upper Cretaceous on the right slope of the Vovcha river near the village of Tyhe in Vovchansky district. The snow-white chalk mountains, which extend through the Vovcha ravine from Vovchansk to the border of Bilhorodska oblast, form a unique object for creating the first geopark in the north of Kharkiv oblast (Manyuk, 2006, 2007). (Fig. 18, 19, 20).

◦ Novomlynski chalk mountains.

On a ledge of the high right bank of the Oskol river, over a length of 33 km, Upper Cretaceous deposits are exposed in numerous steep banks and erosion wash-outs, practically as a single, unified outcrop. They create a unique landscape and have great scientific value.

The Chalk Mountains are one of the main objects of the "Dvorichansky National Natural Park", which was created in 2009 expressly for the purpose of conserving these unique chalk mountains and their flora. In the XVIIIth century, a leading Ukrainian geology researcher

Petro Palas emphasized on the necessity of conservation of the Chalk Mountains and their flora.

Conclusions. The peculiarities of the geological formation of Kharkiv oblast, the relief and general distribution of sedimentary rocks, make it imperative to conduct regular monitoring of the objects of its geological heritage. In the considered list of geosites, 9 out of the 49 geological monuments are recommended to be excluded since they do not correspond to the criteria of the general register. We recommend 16 monuments of local value, 20 of national value, and 4 to be included in the European list. Among other problems, the main problem of conserving the geological heritage of Kharkiv oblast is to solve the problems connected with conferring conservation status on the selected objects. This includes writing an application about the necessity of protecting each newly recommended object of the NRL and presenting it to the Ecology Department of Kharkiv oblast. The application must include the appropriate scientific descriptions and cartographic materials and, following this, observance of the procedures for obtaining consent for the conferring of conservation status upon an object from stakeholders in the land at local, district and oblast levels. An important precondition for providing a geological object with protected status is recognition by all levels of state administration of the necessity of conservation of biological and geological diversity (Wimbledon, 1997). The concept of geological diversity was incorporated into European nature conservation practice due to the activization of the European Association for the Conservation of the Geological Heritage (Pro Geo), the increase in its authority around the world, realization of the necessity of conservation of inanimate nature and development of methodological programs for protecting biological and landscape diversity (Wimbledon & Smith-Meyer (eds), 2012). The problem of conserving biological and landscape diversity should be seen as a multilevel process, which includes legislative, scientific-methodological, socio-economic support for the programs and measures in the nature conservation sphere (Zinko, 2004).
