“…2); these have also been folded and fractured. The overlying carbonate rocks are intensively fractured along the thrust contacts and within wide zones of NW-SE trending strike-slip faults (the Predjama, Vipava and Raša faults) that cut the thrust contact (pLacer, 1981;1998;2008;čar & gospodarič, 1988;janež et al, 1997).…”

“…In tectonic terms, the investigated area is part of a south west verging, Eocene to Oligocene foldand-thrust structure in the External Dinarids (pLacer, 1981;1998). The Šumljak sedimentary bodies are located in the upper part of the Vipava Valley, which belongs to three different nappes (from structurally lowest to highest): The Komen Thrust Sheet, the Snežnik Thrust Sheet and the Hrušica Nappe (Fig.…”

The Rebrnice area forms the north eastern slopes of the Upper Vipava Valley and is located between Karst plateau to the southwest and the Nanos plateau to the northeast. The Rebrnice slopes are geomorphologically defined by a thrust front of Mesozoic carbonates over Tertiary flysch deposits and are characterised by a variety of polygenetic landslides (being the most prominent geomorphological features). Among them, the three Šumljak sedimentary bodies of fossil landslides (approximately 0.56 km² in area) comprise carbonate gravels and breccia. The most distinctive geomorphological element is the planation surface of the carbonate breccia blocks positioned in the hinterland of the Šumljak sedimentary bodies. Another feature is the presence of local escarpments (steep scarps) defining the border between the planation surface in the hinterland and sedimentary bodies.Our research suggests that the whole area in the hinterland of the Šumljak sedimentary bodies form part of a deep-seated rotational landslide formed of carbonate breccia. On the basis of the dipping of the breccia beds, in particular parts of the rotational blocks, the rotation can reach up to 60°. Planation surfaces developed above the curved, sliding plane in the central part and/or slightly outer part of the landslide. Steep scarps on the external parts of the planation surface represent the main scarps of the Šumljak sedimentary bodies. We propose that these bodies originated from the remobilization of material accumulated in outer parts of large-scale rotational slides and its transportation further downslope, mostly by rock avalanches. IzvlečekObmočje Rebrnic predstavlja severnovzhodna pobočja Zgornje Vipavske doline, ki se nahajajo med kraško planoto na jugozahodu in Nanosom na severovzhodu. Topografijo območja Rebrnic opredeljuje čelo narivnega robu mezozojskih karbonatov, ki so narinjeni na terciarne kamnine fliša, kontakt pa prekrivajo kvartarni pobočni sedimenti, med katerimi so najpomembnejši fosilni in recentni poligenetski plazovi. Med fosilnimi plazovi izstopajo tudi tri sedimentna telesa Šumljak (velikosti 0,56 km²), sestavljena iz karbonatnega grušča in breče in imajo specifične geomorfološke značilnosti. Najbolj značilen geomorfološki element so planarne (izravnane) površine blokov karbonatnih breč v zaledju sedimentnih teles Šumljak in prisotnost lokalnih morfoloških stopenj v obliki strmih robov, ki opredeljujejo mejo med izravnano površino v zaledju in sedimentnim telesom.Raziskave kažejo, da je celotno območje v zaledju sedimentnih teles Šumljak lahko del globokih rotacijskih plazov karbonatnih breč. Na podlagi plastnatosti breče na posameznih delih rotacijskih blokov, ugotavljamo, da so bloki rotirali do 60°. Izravnana površina je razvita predvsem v osrednjem delu planarnih površin, na zunanjih delih izravnav pa se pojavljajo strmi robovi, ki predstavljajo glavne odlomne robove sedimentnih teles Šumljak. Menimo, da so telesa, predvsem v zgornjem delu pobočja nastala kot posledica remobilizacije materiala z zunanjih delov v...

“…Two possible variants of its course from there towards northwest are found in the literature. According to the first one (HERAK 1999, PREMRU 1980, 2005, the frontal parts of the Snežnik Thrust Block and of Hru{ica and Trnovo Nappe are connected with a single thrust zone, against which is supposed to lean the Hru{ica and Trnovo Thrust Fault; whereas according to the second variant (BUSER et al, 1967;BU-SER, 1968;PLACER, 1999PLACER, , 2008b, the unique frontal zone has supposedly split into the Hru{ica and Trnovo Thrust Faults. The first variant is based on sedimentological-paleontological research that resulted in the hypothesis of existence of two separated carbonate platforms, the Adriatic and the Dinaric one.…”

Izvle~ekPrispevek prikazuje geolo{ke razmere na Kobli v osrednjem delu Bohinjskega grebena ter zgo{~en zgodovinski pregled raziskav.Prve podrobnej{e raziskave tega prostora so povezane z izgradnjo 6334 m dolgega železni{kega predora med Bohinjsko Bistrico in Podbrdom, odprtega v letu 1906. Ta predor poteka prav pod vrhom Koble in zajema 8 litolo{kih ~lenov. Drugo obdobje raziskav v letih 1969-1987 predstavlja izdelavo Osnovne geolo{ke karte lista Tolmin v merilu 1 : 100.000, v okviru katere je bil ugotovljen obstoj Slovenskega bazena in dveh platform v ~asu od srednjega triasa do konca krede v zahodni Sloveniji. V zadnjem obdobju pa so bile geolo{ke raziskave na prostoru Koble osredoto~ene na podrobno stratigrafijo in litologijo. Analize konodontnih združb in foraminifer kažejo, da pripada del apnencev, ki so bili v okviru OGK uvr{~eni v spodnjo juro, {e zgornjemu triasu.Jurski sedimenti na Kobli so se odlagali v globljevodnem okolju Slovenskega bazena, apnen~eve bre~e in kalkareniti pa z gravitacijskimi tokovi v pregibni coni in v robnem delu bazena. V kalkarenitnem paketu liasne starosti so {tevilni naplavljeni ooidi in krinoidi.
