20.500.12556/DiRROS-14796 Strukturne razmere na stiku Južnih Alp in Dinaridov na zahodnem Cerkljanskem Structural setting at the contact of the Southern Alps and Dinarides in western Cerkljansko region (western Slovenia) Ozemlje med vasmi Reka v dolini Idrijce, Bukovo pod Kojco in Zakriž pri Cerknem pripada v geografskem in geotektonskem pogledu Dinaridom. Gradijo ga kamnine dveh obsežnih narivnih enot Trnovskega pokrova, ki so bile za več deset kilometrov narinjene od severovzhoda proti jugozahodu v današnjo lego. Preko njih so narinjene kamnine Tolminskega pokrova, ki je na obravnavanem ozemlju najnižja narivna enota Južnih Alp. Pokrov sestavljajo dve notranji narivni grudi in vmesna narivna luska. Narivne enote so bile narinjene od severa proti jugu. V zahodnem delu obravnavanega območja stik med Južnimi Alpami in Dinaridi poteka ob Sovodenjskem prelomu.Kljub temu, da so kamnine v obravnavanih narivnih enotah približno enake starosti, lahko prepoznamo dva različna stratigrafska razvoja. Posebej izstopa problematika razvoja ladinijsko-spodnjekarnijskih psevdoziljskih plasti, to je zaporedja klastičnih in karbonatnih kamnin, ki se je odložilo v globljemorskem okolju Slovenskega bazena. Tako v Trnovskem kot tudi v Tolminskem pokrovu najdemo psevdoziljske plasti razvite v podobnem, litološko značilnem zaporedju, a so v Tolminskem pokrovu razvite v precej večji debelini kot v Trnovskem pokrovu in navzgor zvezno prehajajo v amfiklinske plasti, medtem ko je debelina psevdoziljskih plasti v Trnovskem pokrovu precej manjša, v normalnem zaporedju pa na njih leži platformni cordevolski dolomit. The area between the villages of Reka in the Idrijca Valley, Bukovo and Zakriž near Cerkno belongs geographically and geotectonically to the Dinarides. The area consists of two large inner thrust blocks of the Trnovo nappe, which were thrusted for tens of kilometers in the direction of SW to their present position. They are overlain by the Tolmin nappe, the lowest thrust unit of the Southern Alps. The Tolmin nappe was thrusted from N to S and consists of two inner thrust blocks and a smaller intermediate inner sheet. In the western part of the area the contact between Southern Alps and the Dinarides runs along the regional Sovodenj fault.Although the rocks in the considered thrust units are about the same age, different stratigraphic settings could be recognized. The lithostratigraphic features of the Ladinian-Lower Carnian Pseudizilian beds are particularly striking. Succession of clastic and carbonate rocks was deposited in deep-marine Slovenian basin. In both the Trnovo and Tolmin nappe, Pseudozilian beds occur in the lithologically characteristic sequences but, in the Tolmin nappe, they are developed in a much greater thickness than in the Trnovo nappe and pass continuously upwards into Amphyclina beds, while in the Trnovo nappe, on the other hand, the succession of Pseudozilian beds is much thinner and is overlain by the platform Cordevol dolomite. narivna zgradba Trnovski pokrov Tolminski pokrov Južne Alpe Dinaridi Slovenski bazen trias psevdoziljske plasti thrust structure Trnovo nappe Tolmin nappe Southern Alps – Dinarides contact Slovenian basin Triassic Pseudozilian beds true false true Geološki zavod Slovenije Slovenski jezik Angleški jezik Delo ni kategorizirano 2022-03-09 09:26:39 2022-03-09 10:03:39 2022-08-20 03:37:57 0000-00-00 00:00:00 2021 0 0 str. 189-203 no . 2 vol. 64 2021 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 551.7 0016-7789 10.5474/geologija.2021.011 92516611 1816-Article_Text-12342338-1-10-20211227.pdf 1816-Article_Text-12342338-1-10-20211227.pdf 1 95F76F817C725BE86926F9FCC7ED81FB 7d28695d1ac3f0da399dac9a170d4d3b02c15592c2547212e437c20b41fc558d d58f9bba-17b6-11ed-b6b8-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=19077 Geološki zavod Slovenije 0 0 0
