Fossil remains of chondrichthyan tooth bases (roots) were found in Lower Permian beds exposed along the forest road between Dovje and Plavški Rovt. These layers are part of the clastic development of ...the Trogkofel Group beds. They are composed of an alternation of dark to light-grey shales, siltstone, and sandstone with rare beds of the conglomerate. Within the clastic succession, layers or lenses of dark-grey to black limestones (biosparitic, biomicritic and oolitic) and limestone breccias occur. The limestone consists remains of algae, fusulinids, brachiopods, and mostly crinoids (Palermocrinus and Entrochus). Detail study has shown that two remains of tooth bases belong to the genus Petalodus, one of them to the species Petalodus ohioensis. The bases are tongue-shaped and come to a rounded point in the distal (base end) edge. On the surface of the base, the typical oval-shaped foramina are visible. In addition, the osteodentine is visible on the cross-section of one specimen. Teeth of Petalodus are often the most common chondrichthyan fossil vertebrate remains reported from the Carboniferous and Permian rocks of the USA, Europe, and Russia. In Slovenia, Petalodus ohioensis has been recorded only from Upper Carboniferous beds. The new record of Lower Permian remains contributes to the knowledge of this cosmopolitan but still common genus of Late Paleozoic chondrichthyans.
The taxonomy of marine ostracod assemblages from Belca section in the Karavanke Mountains, northwestern Slovenia, is discussed, adding to the scientific understanding of marine ostracods during the ...Carnian stage, Late Triassic. In Belca, the ostracod assemblages include 39 species, among which two are newly described: Dicerobairdia buseri Forel, n. sp. and Pontocypris? karavankensis Forel, n. sp. The recovery of abundant juvenile and adult specimens facilitated the illustration and discussion of the ontogenetic series of several typically Triassic species including Renngartenella sanctaecrucis Kris-tan-Tollmann inKristan-Tollmann & Hamedani, 1973, Leviella bogschiKozur, 1972 and Leviella veghaeKozur, 1972. The occurrence of sexual dimorphism is furthermore confirmed for Renngartenella sanctaecrucis. Ostracods in Belca record a major shift from low diversity and high dominance assemblages at the base of the section to higher diversity and lower dominance with diversification of stable open-marine taxa in the upper part. This pattern might illustrate low salinity levels related to high land-derived input at the base of the section and a return to relatively normal marine salinity in the intermediate sublittoral zone in the upper portion of Belca section.
Crossborder Karavanke/Karawanken UNESCO Global Geopark was established in 2011, and in 2013, it became a member of the European- (EGN) and Global Geopark Network (GGN). Its administrative boundary ...follows the boundaries of 14 municipalities on the Slovenian and Austrian sides. Since the early beginning, the sustainable tourism throughout the region has been developed. An important component of the Geopark activities is applying for various funding to support the regional development through the transnational cooperation between European Geoparks or through Geopark-specifi projects. An example of the transnational cooperation is the project Valorisation of geo-heritage for sustainable and innovative tourism development of Danube Geoparks. Eight Geoparks of the Danube region participate in this project with the acronym Danube GeoTour, implemented in the INTERREG Danube Transnational Programme 2014-2020. The main goal of the project is establishment of the joint Danube GeoTour designed to strengthen cooperation between the regions’ Geoparks and act as an innovative tourism product to accelerate visibility and tourist visits in the Geoparks. Common strategy for sustainable management of tourism pressures will form the basis for creating innovative geoproducts. Sharing experiences, testing pilot geotourism products and new interpretative approaches should increase local inhabitants’ engagement, Geopark management capacities and lower the quality gap between Danube and other European Geoparks. Within the Danube GeoTour project, Karavanke/Karawanken UNESCO Global Geopark implemented a research “New competences in geoheritage interpretation”. The aim of the project is to fid out how to improve skills and quality of the heritage presentation in the participating Geoparks by transnational learning interaction, and to complement the uniqueness and character of the overall Danube GeoTour product. The main research objective was the introduction of new interpretation trends, techniques and methods which are used in the presentation of geoheritage, observed within and outside the participating Geoparks.
The cross-border Geopark Karawanken/ Karavanke was established in 2011 to reflect the diverse geological composition and varied and rich natural and cultural heritage of the area. The wealth of ...geological heritage is reflected in numerous, already existing geosites, exceptional and unique on a global level, as well as in newly determined mineral and fossil sites. An example of the latter is the fossil site with rare Valanginian-Hauterivian heteromorphic ammonites, located in the SE part of the Karawanken/ Karavanke UNESCO Global Geopark, near Leše village above Prevalje. It is the first and newly discovered locality of heteromorphic ammonites Himantoceras trinodosum Thieuloy, 1964 and Crioceratites cf. nolani Kilian, 1910 in Slovenia. We explore the importance and potential of good cooperation between the local community, paleontologists and other geoscientists, geoheritage (paleontological heritage) conservation and UNESCO Global Geoparks.
The paper deals with newly discovered Valanginian-Hauterivian fauna of heteromorphic ammonites (Ancyloceratina) from locality south of the village of Leše above the Meža River valley (North Karavanke ...Mountains). Fossils were recovered from the pelagic limestone. Among the studied heteromorphic ammonites are Lower Cretacaoeus species Himantoceras trinodosum (Upper Valanginian) and Crioceratites cf. nolani (Hauterivian). Based on the accompanied ammonites (Ammonitina) from the outcrop, we biostratigraficaly confirm the presence of Lower Cretaceous ammonites fauna in the Northern Karavanke Mountains. This is also the first report on heteromorphic ammonites in Slovenia.
The Brsnina Permian–Triassic nearshore marine sediments were deposited on the Adria carbonate platform in tropical latitudes at the western end of the Neotethys Ocean. Continuous channel samples ...across the boundary show no consistent change in element or element/Al ratios, except that most element/Al ratios increase in the top 0.5 m of the Permian strata. Though there are sporadic higher values of some element/element ratios, such as Ti/Zr, Th/Sc, Zr/Sc, Cr/Ni, Y/Ni, Co/Th, Cu/Zn, and Nb/Ta, La/Sc, the overall geochemistry indicates that the sediments were derived from dominantly silica-rich continental rather than silica-poor sources though with some more silica-poor inputs at times. Sporadic high Ti/Zr ratios indicate periods of increased aridity, but no overall increase across the boundary. Various geochemical redox proxies suggest mainly oxic depositional conditions, with episodes of anoxia, but with little systematic variation across the boundary. Geochemical proxies for productivity indicate little change up the section with values two orders of magnitude less than elsewhere. The lack of consistent element geochemical changes across the boundary accompanied by significant C, S, and other isotopic changes suggests that atmospheric and oceanic chemical variations drove the Permian–Triassic boundary environmental changes at least on the sabkha environments of the tropical Adria platform.
PURPOSE: The management of cross-border natural resources has been the focus of research in different disciplines. Nonetheless, beyond theoretical insights, empirical evidence of successful ...cross-border management or governance of natural resources is still limited, even in the European Union (EU), where a range of instruments are provided to foster cross-border cooperation between its Member States. This is where our paper departs, providing evidence from an example of cross-border cooperation between two Member States of the EU, Austria, and Slovenia, adding to the analytical framework to identify the drivers of successful cross-border cooperation. METHODOLOGY: Drawing from the example of the European Grouping of Territorial Cooperation (EGTC) Geopark Karawanken we evaluate the success factors and limits for transboundary cooperation encompassing different forms of cooperation. Furthermore, based on empirical evidence of workshops with local, regional, and national stakeholders, we investigate the potential of the EGTC organizational framework to provide for the successful cross-border management of water resources within the Geopark area. FINDINGS: Our analysis of project bundles, joint ventures/consortia, and EGTCs as possible forms of transboundary cooperation indicates that EGTCs have various advantages over looser forms of cooperation. Higher operational costs for the organization are contrasted by enhanced governance of transboundary activities, in accordance with legal frameworks and representation on both sides of the border. This increases acceptance and facilitates decision-making. Furthermore, it increases the potential for receiving funds in accordance with planned activities and regional requirements, while decreasing the individual financial risk for partners. The genesis of the Karawanken/Karavanke UNESCO Global Geopark (Geopark Karawanken) indicates that looser forms of organization, for instance, project bundles, enable stakeholders to get to know each other without great institutional effort. In the course of increasing integration, the organizational form can be more complex. The experience in developing transboundary, water management instruments shows that even in a more sophisticated form of cooperation like an EGTC, there are remaining obstacles in managing transboundary natural resources. Obstacles result from e.g., national laws and regulations, data standards, monitoring techniques, and soft factors such as language barriers. IMPLICATIONS: The example of the Geopark Karawanken shows that cross-border public authorities can be significantly supported with the introduction of an EGTC. Still, an EGTC tends to exclude private companies or societal actors because they cannot be active members of the Board. Exploring further options for closer integration of the private sector in Public-Private-Partnership (PPP) models may be useful to maintain the opportunity to include much-needed private skills and resources. The experience of the Geopark Karawanken suggests that EGTCs can and will be a significant form of organization in Europe for a number of activities, for example, in the field of cross-border resources, cross-border protected areas, or cross-border predicate regions. This will support the achievement of the goals of EU programs to face the climate and biodiversity crises through transnational agreements, e.g., the Green Deal or the Biodiversity Strategy. ORIGINALITY AND VALUE: This article provides a concise overview on transnational water resource management in the European Union in the context of an EGTC, and raises points for practitioners about potential challenges for the successful introduction of an EGTC. While the analysis of common experiences of various EGTCs could lead to the development of a European standard and guideline for the successful foundation of this territorial cohesion tool, this paper provides the first step, paving the road for future research.
From the national digital elevation model DMV 5 of the Western Karavanke longitudinal profies of fitythree torrents were extracted. Longitudinal profies of torrential channels in study area have ...generally convex sections and do not correspond to equilibrium state. In this paper, changes in lithology across faults and other potential inflences are discussed as possible cause for observed convex longitudinal profies. Some typical cases where it has been found, that convex sections could be result of faults, are graphically showed. Also lithology of torrential stream bed could be one of main factors for convexity. This applies in particular if the torrent crosses from soft to solid rock.
The Periadriatic lineament extends from the Sesia zone in Italyacross southern Austria into Slovenia, in the area of the Karavankemountains. It continues eastwards into the Pannonian basin in ...Hungaryas the Balaton line. The Karavanke mountain range runs fromSlovenia in the east westwards into the Carnian Alps of Austria. Furthereast they extend beneath the Tertiary sediments of the Pannonianbasin into Hungary. The Karavanke mountains represent a boundaryzone between the Eastern Alps to the north and the Julian and Savinja-Kamnik Alps or Southern Alps to the south. The Periadriatic lineamentintersects the eastern part of the Karavanke mountains fromAustria, trending eastwards, dividing this unit into the Northern andSouthern Karavanke.Geologically, the Karavanke mountains consist of Palaeozoic,Mesozoic (moslly Triassic) rocks and Tertiary sediments. In the eastern part of the Karavanke mountains, along the Periadriatic lineament,there is a belt of magmatic rocks, granite in the north andtonalite in the south, with a narrow belt of metamorphic rocks inbetween.The tectonic structure of the aforementioned boundary zone isespecially interesting.

We analysed spatial development of traditional and modern settlements on active alluvial fans in the Upper Sava Valley (NW Slovenia), by using old cadastral data from the beginning of the 19th ...century, time series of aerial photographs from the middle of the 20th century and recent building cadastre. The valley is surrounded by the mountainous Julian Alps in the south and the Karavanke Mountains in the north where there is a lack of space for settlements due to steep slopes that are increasing the danger of slope processes, torrential processes and floods. By using a very high-resolution 1m LiDAR digital elevation model, we defined the morphometry of alluvial fans and the characteristics of the drainage system of contributing tributaries. We classified the areas according to the threat posed by the modelled torrents and debris flows. We analysed the resilience of settlement in different periods from this perspective and evaluated the integration of natural processes effects in modern spatial planning projects. We found that geomorphic processes threaten a relatively large proportion of some new and old settlements on alluvial fans and that safe planning of areas of settlement has been successful neither in the past nor in recent decades.
