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.
Deseti Dan slovenskih planincev, 10. 9. 1978, je PD Luče združilo z odprtjem obnovljene Koče pod Raduho. To je bila prilika, da se srečamo planinski prijatelji od blizu in daleč. Izpod Snežnika nas ...je prišel poln avtobus planincev. Skupaj z domačini smo se iskreno veselili lepega dogodka. Na sliki smo pred novo planinsko postojanko nekateri znani organizatorji mladinske planinske dejavnosti v Sloveniji. Z leve stojijo: Milan Mahovne iz PD Sevnica, Dragica Onič iz PD Poljčane, pred njo sedi soprog Franček s sinom Tomažem, zadaj Filip Matko Filutek iz PD Luče (oblikovalec planinskega grba in prapora PD Snežnik) in Vojko Čeligoj iz PD Ilirska Bistrica.Tekst Vojko Čeligoj, foto Sonja Čeligoj
Volcanic rocks occurring in Ladinian (?) marls, interstratified with limestone (Solčava beds), at Grohat Alpine Meadow and Lipni plaz, Mt. Raduha, are shallow intrusives bodies with porphyric ...structure, and basaltic andesitic, acid andesitic and dacitic composition.Abundance of major oxides and trace elements in the studied rocks is similar to those observed in the Tertiary Smrekovec volcanic rocks suggesting contemporaneous formation and close genetic relationship.
