The segment has a rather complex geological structure. The Svydovets massif is characterized by a complex division of structural overthrust sheets – Dukliansky, Porkuletsky and Chornohirsky overthrusts. The northern part of the site is located in the Slavsko-Verkhovynsky subzone of the Krosno zone. The Dukliansky overthrust represents Svydivets and Blyznytsia subzones, the Porkuletsky overthrust represents the Luzhansky subzone, and Chornohirsky – Yalovychorsky or Hoverliansky subzones. Each overthrust sheet shows the presence of ridgelike anticlinal folds that are deformed by thrusts and faults in fold parts. The Krosno zone is blocked by the thrusts of the Dukliansky and Chornohirsky overthrust sheets. A significant area within the study segment is occupied by the Inner Gorgans (near the water divide), which are confined to the raised base of the Silesian sheet, where the Gorgan folds were formed. The main morphostructural element is the massive Bratkivsky ridge, whose structure is dominated by resistant rocks of the Paleocene and Eocene, in particular the sandstones of the Yamna and Vyhodsky suites. The territory of the Chorna Tysa basin upper part is located in a seismic zone where resonant earthquakes of magnitude 4-6 periodically occur. Slow tectonic movements in this area are +1.5 –2.0 mm per year. Apart from analyzing the geological structure of the Chorna Tysa basin segment, which is a promising area for recreation and touristic development, this paper aims to outline the possibilities of using the geological structure and relief to develop educational forms of tourism, including geotourism. It is most often the geological structure (tectonics, diversity of rocks, long history of geological development, formation of mountain relief, etc.) that creates attractive sites – picturesque landscapes, outcrops of rocks, peaks, relict landforms, waterfalls, gregots, i.e., massive rock stream accumulation, and others). It can thus be concluded that the geological structure is crucial in forming promising tourism and recreation proposals and in the development of prospective infrastructure. Therefore, it is imperative to keep in mind the geological structure and landforms, when planning the development of recreation and tourism. Key words: geological structure (tectonics and lithology); landform, recreation and tourism; geotourism; geotourism attractions; Chorna Tysa; Ukrainian Carpathians. |
