The radial growth of the trunks of the following flora species which do not have special protection on the southern hillsides of Greater Caucasus was studied in the article: Georgioan oak- Quercus iberica M.Bieb Common hornbeam - Caprinus betulus L. Common chestnut - Castanea sativa Mill. Black walnut - Juglans nigra L., Heart leaved alder - Alnus subcordata C.A.Mey. During the dendrochronological analyses, the dynamics of growth over the years were analysed based on the distances between the tree rings. The impact of the climatic factors on the growth of the trees was analysed and the ages of tree species were investigated. Based on the dendrochronological historical application, according to the numbers of tree rings, the ages of the trees were defined in the studied species. According to the numbers of tree rings, the oldest type of the rare and scanty flora types which have no special protection was identified as Caprinus betulus L. in the Zagatala region. The tree was taken from Zagatala district, planted in 1944, was 75 years old and had 330 cm diameter. The observation of dendrochronological researches indicates the formation of a new microclimate. It was observed that in the investigated species, radial growth was more intense during matureness, then it was weakened with age. In the comparative analysis, it was observed that the minimum radial growth was in 2010 and 2015, and the maximum growth was between 1973 and 1985 in the Zagatala region

<p>Natural geosystems of the south-eastern slope of the Greater Caucasus are genetically related to the large morphostructural units that constitute the territory, as well as to the aerodynamic condition of the lower layer of the troposphere. The study revealed that there are contradictions in the geosystems formation of various local morphostructures. Thus, the differentiation of geosystems may either be intensifi or weakened, depending on the height of mountain areas and ridges. The slope and direction of visibility of the area are the basic elements that play a decisive role in the shaping of structural and genetic features of the area in question. The article features the structural changes that are observed in natural geosystems based on the slope and direction of visibility maps and charts of the contemporary geosystems in the south-eastern slope of the Greater Caucasus. The research also features the infl of morphometric parameters of the relief on the agriculture development in the mountain geosystems of the south-eastern slope of the Greater Caucasus in GIS.<strong></strong></p>

Like other mountainous regions of the Caucasus, the South-Eastern Caucasus is an epigeosynclinal mountain system formed by the first and middle alpine folds. Between the Alpine fold stage and the orogenic stage, the South-East Caucasus Mountains were denuded and turned into hilly, low mountain plains in the Oligocene and Miocene. Wrinkled structures were destroyed by denudation and a mostly neutral relief type was formed. Key words: Greater Caucasus, southern slope of the Greater Caucasus, morphostructure, wrinkled relief, geological development

The aim of the work was to study the geopolitical processes in the South Caucasus, representing the “Eurasian Balkans”. Based on the discourse analysis, the geopolitical position of the region and the geopolitical interests of its main actors were considered. The transformation of the Karabakh knot of geopolitical contradictions from a regional confrontation into a special “chess game” with the active participation of Western countries is shown. In this game Turkey is trying to become the leading center for development a new geopolitical structure of interaction between the Eurasian Turkic-speaking states as opposed to the Russian Eurasian project. It is concluded that only Russia can become the guarantor of peace and exert geopolitical influence on the wider region of the Greater Caucasus.

В статье рассмотрены условия формирования складчатой системы Большого Кавказа в альпийскую эпоху. Показано, что главная зональная линейная складчатая структура региона была сформирована на ранне- и среднеальпийской стадиях развития в результате проявления батской и пиренейской фаз складчатости. Установлено, что причиной складкообразования было активное столкновение Черноморско-Закавказского микроконтинента на юго-западе с пассивной окраиной Большого Кавказа. Определено, что позднеальпийская стадия в регионе проходила в условиях субмеридионального тангенциального давления, во время проявления плиоцен-четвертичных фаз складчатости. В это время на Большой Кавказ воздействовал не целостный Черноморско-Закавказский микроконтинент, а слагающие его мелкие плиты и блоки-шоли. Выяснено, что они в процессе тектогенеза перемещались и косо вдвигались в складчатую систему Большого Кавказа, вызывая преобразование первичной структуры и возникновение интерференционной складчатости. В результате повторного деформирования отдельных участков региона в его пределах образовалась неоднородная складчатая структура. Изучена основная особенность складчатой системы Большого Кавказа, выраженная структурной неоднородностью складчатости в поперечном и продольном направлениях. Установлено, что она отражает поэтапную и разноплановую деформацию отдельных участков, возникающую в результате последовательного проявления в регионе локальной и региональной геодинамики микроконтинента, а также связанных с ними общих и частных механизмов его формирования. Структурный анализ морфологии складчатости БК действительно показал неравномерную дислоцированность его – С-З и Ю-В сегментов, сложенных в основном ранне- и среднеальпийскими структурами, выраженную в разной степени осложненности коллизионными деформациями. Так, в пределах мальм-эоценового структурного этажа С-З Кавказа, раннеальпийская структура которого меньше всех остальных сегментов усложнена коллизионными деформациями, четко проявлена латеральная асимметричная зональность его складчатой структуры.  Она выражена в последовательной смене с юго-запада на северо-восток интенсивной линейной сильно сжатой складчатости линейными гребневидными, а затем слабо вытянутыми типичными брахиморфными складками, переходящими, в свою очередь, в полого наклонную на северо-восток моноклиналь The article considers the conditions of formation of folded system of the Greater Caucasus in the Alpine Epoch. It is shown that main zonal linear folded structure of the region was formed at the early and middle Alpine stages of the evolution in the result of manifestation of Bathonian and Pyrenean stages of folding. It was established that the cause of the folding was an active collision of the Black Sea-Transcaucasian microcontinent in the south-west with the passive margin of the Greater Caucasus. It was also determined that the Late Alpine stage in the region took place under the conditions ofsubmeridional tangential stress, during the Pliocene-Quarternary folding phases. During this period the Greater Caucasus was affected not by the whole Black Sea-Transcaucasian microcontinent, but by its smaller plates and blocks. It was found out that during the process of tectogenesis they drifted and obliquely moved into the folded system of the Greater Caucasus, causing the transformation of the initial structure and the occurrence of interferential folding. In the result of repeated deformation of separate areas of the region the heterogeneous folded structure was formed. The main feature of the folded structures of the Greater Caucasus (expressed by a structural heterogeny in transversal and longitudinal directions) was studied. It was determined that it reflects the gradual and diverse deformation of individual sections, resulting from the consistent manifestation of the local and regional geodynamics of the microcontinent, as well as the common and specific mechanisms of its formation associated with them. The structural analysis of the morphology of folding of the Great Caucasus really showed its uneven dislocation, i.e. the N-W and S-E of the segments, composed mainly of early and middle Alpine structures, expressed in varying degrees of complication by collisional deformations. So, within the Malm-Eocene structural floor of the northwestern Caucasus, the Early Alpine structure of which is less than all the other segments, is complicated by collimated deformations, the lateral asymmetric zonality of its folded structure is clearly manifested. It is expressed in a successive change from the south-west to the north-east of intensive linear highly compressed folding with linear ridge-like, and then slightly elongated typical brachymorphic folds, which turn into a hollow sloping to the north-east monocline
