“…However, the dip of the sampled terraces is indicating the sediment supply from the south. Regarding these two contradictory arguments, we propose that ether i) these metamorphic clasts are resedimented from older (possibly Miocene; Ivančič et al, 2017) deposits from the south of the CB, which were originally deposited from the north or that ii) the present day dip of the terrace surfaces is a result of post-sedimentary tectonics and does not correspond to the direction of the drainage system in the Plio-Early Pleistocene.…”

“…Glede na nasprotujoča si argumenta se porajajo dodatne interpretacije, in sicer i) da so prodniki omenjene litologije resedimentirani iz nanosov starejših paleopritokov, ki so prihajali s severa (miocenski sedimenti? ; Ivančič et al, 2017) ali pa ii), da je današnji nagib teras rezultat post-sedimentacijske tektonike in ne ustreza smeri drenaže v plio-zgodnjempleistocenu.…”

This study presents the results of the first systematic morphostratigraphic and provenance analyses of the Pliocene-Quaternary fluvial sediments in the Celje and Drava-Ptuj intramontane basins. Based on the degree of terrace preservation, the dip of the terrace surfaces and fans, and the composition and degree of weathering of the sediments, low-, middle-and high-level terrace groups were constrained and tentatively attributed to Late Pleistocene, Middle Pleistocene and Plio-Early Pleistocene, respectively. The provenance analysis focused on the sediments from the high-level terrace (Plio-Early Pleistocene) and encompassed clast lithological analysis and microfacies analysis of the clasts. The results indicate a local provenance with relatively short transport, which is consistent with the morphology of the clasts. The source rocks of the Plio-Early Pleistocene deposits in the Celje Basin are attributed to the formations outcropping in the southern Pohorje Massif and the Upper Savinja River Valley corresponding to the paleo-Savinja. The possibility of resedimentation of the clasts from Miocene clastic sedimentary rocks located north of the Celje Basin also needs to be considered. The sediments of the Drava-Ptuj Basin originate from the Pohorje Massif, the Kozjak mountain range, and the area south of the Pohorje Massif which were deposited by the paleo-Drava and paleo-Dravinja rivers. Our study indicates that the drainage systems of the paleo-Savinja, paleo-Drava and paleo-Dravinja during the Plio-Early Pleistocene roughly correspond to those of the present day. Izvleček Predstavljamo prve sistematične analize morfostratigrafije in provenience pliocensko-kvartarnih rečnih sedimentov na območju Celjskega in Dravsko-Ptujskega medgorskega bazena. Na podlagi stopnje ohranjenosti morfologije teras, naklona terasnih površin in sestave ter stopnje preperelosti sedimentov so bili opredeljeni trije terasni nivoji in interpretirane starosti teras in vršajev. Spodnjemu terasnemu nivoju je bila interpretativno določena poznopleistocenska starost, srednjemu terasnemu nivoju srednjepleistocenska, zgornjemu terasnemu nivoju pa plio-zgodnjepleistocenska starost. Analiza provenience je bila osredotočena na sedimente višjega terasnega nivoja (pliocen-zgodnji pleistocen) in je temeljila na litološki analizi klastov in analizi mikrofaciesov klastov. Rezultati nakazujejo, da gre za lokalno provenienco proda, kar dodatno potrjujejo sedimentološka opazovanja morfologije klastov. Izvor plio-zgodnjepleistocenskih sedimentov v Celjskem bazenu so domnevno formacije, ki izdanjajo na območju južnega Pohorja in Zgornjesavinjske doline, pri čemer pa moramo upoštevati

“…It is surrounded by tectonic units of the Eastern and Southern Alps, toward which the contacts are normal or reversely reactivated faults, and it belongs to the PBS by origin (Trajanova 2011(Trajanova , 2013. The basin is underlain by Old-Paleozoic formations, Mesozoic carbonate rock (Mioč & Žnidarčič 1976;Mioč 1978), and Oligocene tonalite (Ivančič et al 2018), and filled with the Middle Miocene typical molasse sedimentary succession named Ivnik beds. They consist of alternating beds of conglomerates, sandstones, siltstones, marlstones, and claystones, and are overlain by Pliocene-Quaternary clastic sediments (Mioč 1978;Mioč & Žnidarčič 1983;Ivančič et al 2018).…”

“…Marginal parts of the western Central Paratethys with Southalpine / Dinaric basement are cropping out in the sedimentary successions of eastern Slovenia, including the area east of Celje, and the wider Laško and Krško area, whereas the basins of north-western Slovenia, including the herein investigated Slovenj Gradec Basin (SGB), have ALCAPA basement (Mioč & Žnidarčič 2001;Hasenhüttl et al 2001;Rižnar et al 2002;Otoničar & Cimerman 2006;Schmid et al 2008;Vrabec et al 2009;Poljak et al 2016;Ivančič et al 2018). The sediments were formed in two main basins: the Mura-Zala, and the Styrian Basins (Mioč & Žnidarčič 1989;Stingl 1994;Ebner & Sachsenhofer 1995;Piller et al 2004Piller et al , 2007Hohenegger et al 2009;Vrabec et al 2009;Fodor et al 2011).…”

It is related mostly to the Mura-Zala Basin, but similarly to the Lavanttal subbasin, it also shares characteristics with the Styrian Basin.…”

The Miocene evolution of the area transitional from the Eastern Alps to the Pannonian Basin System was studied through the paleogeographic evolution of the Slovenj Gradec Basin in northern Slovenia. It is based on mapping, section logging, nannoplankton biostratigraphy, and petrography. The results are correlated with the lithological column of the borehole MD-1/05. The evolution of the basin is connected with the development of the Pannonian Basin System, and the global 3rd order cycles, which influenced the connection with the Mediterranean Sea. Sedimentation started in the Karpatian in a fluvial to lacustrine environment and terminated at the end of the Early Badenian. During this period, three transgression–regression cycles were recorded. The first transgression occurred in the Karpatian and corresponds to the TB 2.2. cycle. The sediments reflect proximity of the hinterland. After a short break in sedimentation, the Early Badenian deposition followed. It marks the second transgression into the SGB, the first Badenian, correlated with the TB 2.3 cycle. There are signs of a transitional environment, which evolved to marine in advanced stages. At the high-stand system tract, the sea flooded the entire Slovenj Gradec Basin. Subsequent reduced quantity and diversity of the microfossils marks the onset of the second regression stage. It is followed by the third transgression, the second in the Badenian, correlated with the TB 2.4 cycle. The late Early Badenian deposition continued in the lower-energy, though occasionally still turbulent environment. Silty sediments with upward increasing content of organic matter indicate shallowing of the basin, until its final diminishing. Layers of fresh-water coal already bear witness to the existence of restricted swamps. After the Early Badenian, the area of the Slovenj Gradec Basin became dry land, exposed to erosion.

This study focuses on the Plio‐Pleistocene fluvial deposits preserved in the terrace staircases in the south‐eastern Alpine foreland of the Mislinja (MV) and Upper Savinja valleys (USV) in northern Slovenia. The area is located at the north‐eastern margin of the Adria microplate, where neotectonic activity is the prevailing driving force for the terrace formation. The aim of this study is to determine the morphostratigraphy and provenance of the Pliocene to Early Pleistocene gravels using geomorphic and clast lithological analysis. The established morphostratigraphic framework encompasses three terraces in the MV and five terraces in the USV. Due to the lack of age‐relevant data, the morphostratigraphy of the MV and USV is based on the results of geomorphic analysis, clast petrography and data from the literature. Low‐level, middle‐level and high‐level terrace groups were tentatively attributed to the Late and Middle Pleistocene, Early Pleistocene–Pliocene and Pliocene, and compared with the traditional Quaternary stratigraphy of the Alpine foreland. The results of the clast lithological analysis revealed major provenance areas. Moreover, the evolution of long‐term drainage from the Miocene onward was inferred, which suggests that the system reached conformity with the present‐day drainage pattern at the Miocene to Plio‐Pleistocene transition.
