V prispevku je predstavljeno proučevanje funkcijske preobrazbe starih mestnih središč na primeru Kranja, Kamnika in Škofje Loke. Raziskava temelji na analizi sprememb v rabi tal med različnimi ...izbranimi časovnimi obdobji. Rabo tal smo ugotavljali s pomočjo terenskega kartiranja in na osnovi različnih virov ter literature. S pomočjo anketiranja lastnikov in najemnikov poslovnih prostorov smo proučevali vrednotenje pogojev za poslovanje v starih mestnih središčih. Na ta način so bili identificirani različni procesi funkcijske preobrazbe.

Nine archaeological bituminous potsherds from the Neolithic of Maliq and Kamnik (5000–4500 BCE) in Albania were geochemically compared for the first time to four natural asphalts from the famous ...present-day mine of Selenicë. The bitumen on potsherds originates from Selenicë, a unique source in Albania and the southern Balkans. Carbon isotopes on the asphaltene chromatographic fraction confirm that the bitumen on the potsherds came from Selenicë. Carbon and hydrogen isotopes on saturates, aromatics, NSO, and asphaltenes show changes that may be due to biodegradation-oxidation effects and also the occurrence of organic remains from the content of the vessels mixed with bitumens. Steranes, terpanes, and aromatics confirm the increased biodegradation of bitumen on potsherds when compared to natural asphalts references.
In the Kamnik-Savinja Alps (Slovenia), the Lower Serla Dolomite laterally passes into a succession of thin- to medium-bedded bituminous limestones of the Velika planina member. The finely laminated ...lower part of this member contains well-preserved actinopterygian fish and sauropterygian remains. The research aimed to determine the sedimentological and palaeoenvironmental characteristics of the depositional basin on the basis of three detailed sedimentological sections logged atop the Velika planina plateau. The Velika planina member is underlain by a whitish to light grey, thick bedded to massive dolomite with oncoids, stromatolites, and lumachellas deposited under peritidal to shallow subtidal conditions. The lower part of the Velika planina member consists of thin, often platy, finely laminated beds of bituminous mudstone. The Chondrites ichnofossil is very common; however, in some beds numerous lingulid brachiopods, bivalves, and crinoids were observed. Fossil vertebrates and crustaceans are relatively rare and confined to a few levels. Ammonoids are very rare. Subordinate beds of intraclastic-peloid wackestone to packstone, intraclastic-bioclastic grainstone, and bivalve floatstone occur. Slumps are common. Upwards, bedding gradually becomes thicker and bioturbation more common. Finally, stromatolites, birdseye fenestrae, and oncoids reappear. The entire succession is confined to the early to middle Anisian by the foraminifer Citaella dinarica (KOCHANSKY-DEVIDÉ & PANTIĆ). The absence of breccias at the base of the Velika planina member, the gradual transition upwards into shallow marine carbonates, as well as the presence of sauropterygians of the order Nothosauroidea suggest deposition in a relatively shallow basin. The finely laminated facies of the lower part of the member indicates a stratified water column, with oxygenated near-surface waters and hypoxic to anoxic conditions near the sea floor.
Članek obravnava metodološke probleme vrednotenja geodiverzitete na primeru Krajinskega parka Logarska dolina. V njem sta predstavljeni in primerjani dve delno avtomatizirani metodi vrednotenja: prva ...združuje prostorsko odvisnost števila geomorfoloških in hidroloških elementov geodiverzitete s podatki o hrapavosti površja, druga pa upošteva tudi litološko sestavo. Indeksi geodiverzitete so bili izračunani z velikostjo rastrskih kvadratov 50 × 50 m z namenom primerjav in ugotavljanja posplošitev na preučevanem območju. Ugotovljeno je bilo, da vključitev litoloških elementov ni smiselna, če je litologija v vrednotenje že vključena preko geomorfoloških elementov, če z množenjem le poveča vrednost območij z visokim indeksom hrapavosti ali če so si tipi litoloških enot glede na značilnosti podobni.
Caves are important markers of surface evolution, since they are, as a general rule, linked with ancient valley bottoms by their springs. However, caves can only be dated indirectly by means of the ...sediments they contain. If the sediment is older than common dating methods, one has to use multiple dating approaches in order to get meaningful results. U/Th dating, palaeomagnetic analysis of flowstone and sediment profiles, cosmogenic dating of quartz pebbles, and mammalian dating allowed a robust estimate of speleogenesis, sediment deposition, climatic change at the surface, and uplift history on the Periadriatic fault line during the Plio-Pleistocene. Our dates indicate that Snežna jama was formed in the (Upper) Miocene, received its sedimentary deposits during the Pliocene in a rather low-lying, hilly landscape, and became inactive due to uplift along the Periadriatic and Sava faults and climatic changes at the beginning of the Quaternary. Although it is only a single cave, the information contained within it makes it an important site of the Southern Alps.
•We present a comprehensive dating approach to sediments of a Slovenian cave.•We interpret the results in the light of climatic change and tectonic uplift.•We show that collaborative work on one single cave can yield results of broader interest.
Debris floods can cause large economic damage and endanger human lives. This paper presents an extreme May 2018 debris flood that occurred in northern Slovenia near the Krvavec ski resort and caused ...large economic damage. The debris flood was initiated by an extreme rainfall event with a return period of over 50 years. There were large differences in the measured rainfall amounts using different equipment. The estimated volume of the debris material during the event was 4000 m

for the Brezovški graben. In order to mitigate the risk due to future debris flood and debris flow events, a check is planned to be constructed. The part of the design process is presented in this paper. Additionally, RAMMS model was used to validate the empirical equations that were used in the process of the check dam stability design. The model was calibrated using information about the deposition area. Two adjacent torrents were modelled, and we were not able to find a common RAMMS parameter set that would yield adequate simulation performance in both cases.
The area of the eastern Kamnik-Savinja Alps was glaciated in the time of the Last Pleistocene Glacial Maximum (LGM). The glacial landforms mentioned by the previous researchers and other landforms in ...the area were examined, gemorphologically mapped, morphographically and morphometrically analysed and a new map of the extent of the LGM was produced. The research revealed several glaciers in the area and that their sizes differed, primarily depending on the slope inclination direction.
The Skuta Glacier in the Kamnik–Savinja Alps (in northern Slovenia) is one of the two remaining glaciers in Slovenia. It is located in a cirque oriented toward the northwest, which shields it from ...sunlight for most of the year. The glacier lies at an average elevation of 2070m. In recent years, its average area has measured around 1.5 hectares. Monitoring of the glacier has been performed since 1946. In 1962, regular photographing of the glacier with various cameras started from various non-fixed standpoints. Using the single image interactive orientation acquisition method, in which a single photograph is compared with the projection of a modern digital terrain model, seventeen photographs covering the period from 1970 to 2015 were used to acquire the 3D-perimeters of the glacier. The data shows that the elevation of glacier’s upper edge decreased by approximately 40m in the last half-century. Changes in the glacier’s area and average upper edge elevation were compared with average annual temperature and maximum seasonal snow cover depth.
