V. Lomonosov”, Moscow, [email protected] ABSTRACT. Geosite “Iron Gate” (“Demirkapiya”) is situated on the territory of Samokov Municipality, Sofiа District. It is in the glacier valley of Beli Iskar River between the summits of Golyam Skakavets (2705.9 m) and Musala (2925.4 m). Geosite “Iron Gate” is of aesthetic and scientific value. It includes the deepest part of the largest glacier valley on the Balkan Peninsula carved out by the Beli Iskar glacier during the Würm Ice Age. This is the deepest place in the valley called "Demirkapiya" or "Iron Gate", due to the impressive displacement of 1250 m between the riverbed and the surrounding peaks. The Beli Iskar River valley is a typical U-shaped glacier trough valley with steep slopes and rounded bottom and a length of 21 km between Kanara Cirque and Beli Iskar village. Side glacier moraines on both slopes of the valley are formed during the ice age and covered later by supraglacial moraines (scree slopes). They consist of angular or somewhat rounded particles, ranging in size from large boulders to glacial flour, obtained as a result of the rocks disintegration. The monolith granite of the Musala Body of the Rila-West Rhodopean Batholith is cut by numerous pegmatite, aplite and quartz veins, vein-like granite bodies and dykes of diorite and granite porphyry, suitable for demonstration of the principle of cross-cutting relationships in geology. Other important geoconservation features of the site are the glacial and periglacial landforms and deposits, which may serve for demonstration of the manner in which glaciers work. The area is on the territory of the National Park Rila with restricted measures, according to the requirements of such category protected areas.

Геотоп "Желязна врата" ("Демиркапия") се намира на територията на община Самоков, област София. Той e в ледниковата долина на р. Бели Искър между върховете Голям Скакавец (2705.9) и Мусала (2925.4). Геотоп "Желязна врата" е с естетическа и научна стойност. Той включва най- дълбоката част от най-голямата ледникова долина на Балканския полуостров, издълбана от белиискърския ледник по време на Вюрмската ледникова епоха. Това е най-дълбокото място в долината "Демиркапия" или "Желязна врата", поради внушителната денивелация от 1250 м между речното корито и околните върхове. Долината на река Бели Искър е типична U-образна ледникова долина със стръмни склонове и заоблено дъно и дължина 21 km между Канарския циркус и с. Бели Искър. Страничните ледникови морени по двата склона на долината са образувани по време на ледниковата епоха и покрити по-късно от супраглациални склонови морени. Те се състоят от ръбати или леко заоблени късове, вариращи от големи блокове до ледниково брашно, получени в резултат на разпадането на скалите. Монолитният гранит на Мусаленското тяло на Рило-Западнородопския батолит се пресича от множество пегматитни, аплитни и кварцови жили, жилоподобни гранитни тела и дайки от диорит и гранит-порфир, подходящи за демонстриране на принципа на секущите взаимоотношения в геологията. Други важни консервационни характеристики на територията са ледниковите и периглациалните ландшафти и отложения, които могат да служат за демонстрация на начина, по който действат ледниците. Районът е разположен на територията на Национален парк "Рила" с ограничени мерки, съгласно изискванията на тази категория защитени територии.

It is in the glacier valley of Beli Iskar River between the summits of Golyam Skakavets (2705.9 m) and Musala (2925.4 m). Geological setting Coordinates of the moraines near the road to Beli Iskar Dam are: 34Т 0710994 E, 4673564 N. This point is situated 14 km The area has a simple geological structure. The first data south of Samokov town and 8 km south of Beli Iskar village. about the native rocks belong to Viquenel (1852) who noted that the granite forms peaks with a height of 2500-3000 m and occupies the heights from which Maritsa River expires. On the Category watershed between Maritsa and Iskar, the author described white coarse-grained granite and gray granite. Geosite “Iron Gate” is of aesthetic and scientific value. This is the deepest place of the deepest and longest glacier valley on Hochstetter (1870) also noted Rila granite as the largest the Balkans - the Beli Iskar River Valley with a displacement of granite massive in the old crystalline body of the Rhodopes. 5 JOURNAL OF MINING AND GEOLOGICAL SCIENCES, Vol. 61, Part I, Geology and Geophysics, 2018 Entering the Beli Iskar River Valley from the north, he phases of postmetamorphic pluton with high potassium- described mica gneiss with layers of amphibolite gneiss, calcium-alkaline character. crystalline
