Abstract
Potočka zijalka was a station of Aurignatien hunters and the site of rich fossil remains of Pleistocene large mammals. Clastic sediments were deposited in Würm and are an intimate mixture of gravel, sand, silt and clay occurring in various proportions. The fractions form distinct populations, which were transported by different agents, like rockfall, flowing water, ephemeral torrent flows and cryoturbation. The sediment constituents are petrologically rather diverse and indicate that they were derived from different parent rocks - Mesozoic limestone, Permian-Carboniferous shales, Tertiary fine-grained sediments and fluvial pebbly deposits. Bulk chemical composition is strongly influenced by the limestone component, but the majority of trace elements, like Ti, Li, V, Fe, Co, Zn, Ga, Y, REE, Zr, Nb, Cs, Hf and Th originates from clay and fine silt, and Mn, Pb, Ni, Cu and Sn mainly from the heavz minerals in the sand fraction. Ca, Mg, Br, Rb, Sr and U show strong correlation with the amount of carbonate component. Rare earth elements, normalised to PAAS are not appreciable fractionated and show light positive europium anomalies.
Highlights
Poto~ka zijalka is located on southwestern flanks of Mt
Clastic sediments were deposited in Würm and are an intimate mixture of gravel, sand, silt and clay occurring in various proportions
The cave became famous after the remains of Pliocene mammals, the cave bear, and the traces of Aurignacien culture were found in its Polona Kralj & Bernarda Bole
Summary
Poto~ka zijalka je bila postaja aurignacienskih lovcev in je zato tudi bogato nahajali{~e fosilnih ostankov velikih pleistocenskih sesalcev. Klasti~ni sediment je nastal v würmu in predstavlja me{anico gru{~a, proda, peska, melja in gline v najrazli~nej{ih razmerjih. Ki so bile transportirane z razli~nimi dejavniki transporta kot so prosti pad, teko~a voda, ob~asni hudourni{ki tokovi in krioturbacija. Ki izvirajo iz razli~nih vrst kamnin – mezozojskih apnencev, permokarbonskih skrilavcev, terciarnih drobnozrnatih sedimentov in re~nih prodov. Ve~ina slednih prvin, kot so Ti, Li, V, Fe, Co, Zn, Ga, Y, prvine redkih zemelj, Zr, Nb, Cs, Hf in Th izvira iz gline in melja, Mn, Pb, Ni, Cu in Sn pa iz te‘ke frakcije peskov. Normalizirane na PAAS, ne ka‘ejo mo~ne frakcionacije, temve~ le manj{o pozitivno evropijevo anomalijo
