The East Balkan offers picturesque mountain landscapes predetermined by а remarkable geological diversity: caves, waterfalls, karst springs and precipices, fossil deposits, stratigraphical, paleontological, tectonic and fossil slump phenomena. In its most attractive part, the Kotel Balkan, there are 28 natural landmarks, 3 protected areas and 2 reserves. Expanding the inventory with purely geological sites, such as fossils, olistostromes, thrusts, geological cycles and events, complemented by many historical sites and intangible cultural heritage (Karakachan minority traditions, craft and folklore festivals), the region of Kotel has excellent preconditions for a geopark development.
Fossil deposit first described by Franz Toula in 1890, in the Garnyovitsa area near Kotel is estimated as a geosite of a national significance with historical value for the Bulgarian geology. Here is cropping out a huge marl olistolith embedded among Middle Jurassic turbidites of the Kotel Olistostrome Formation. It contains Late Triassic (Norian) hydrozoa and corals, identified by the first explorers of the Bulgarian lands as early as the end of the 19th century. Given the high geodiversity of the area and the proximity to Kotel, this geosite has great potential for geotourism within the future geopark “East Balkan”.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
