“…Thus, it is possible that the mid-Langhian flooding was triggered by this global sea-level rise. The rise is in agreement with the fact that the fully marine water transgressed far over the platforms next to the foredeeps, rapidly transformed lakes into marine basins (Kovačić et al 2016;Krézsek and Bally 2006;Pavelić and Kovačić 2018) and spilled over into the Eastern Paratethys via the Carasu strait (Goncharova and Il'ina 1997;Holcová et al 2018;Palcu et al 2019) (Fig. 6b).…”

“…In addition, the use of ambiguous formation names and/or regional fossil assemblages may result in a variable and contradictory correlations (Melinte-Dobrinescu and Stoica 2014;Săndulescu 1988;Mărunţeanu 1999;Beldean et al 2012;de Leeuw et al 2013;). All of the factors above complicate correlation of the stratigraphy from different regions to each other, and to the global time scale (Paucă 1976;Krézsek and Bally 2006 and references therein;Beldean et al 2013;Gozhyk et al 2015;Holcová et al 2018;Kováč et al 2018) hampering paleogeographic and paleoenvironmental reconstructions of the whole Central Paratethys system.…”

The mid-Langhian ("Badenian") flooding fully reconnected the semi-isolated Central Paratethys realm with the Mediterranean and, thereby, drastically changed the middle Miocene paleogeography of Central Europe. Due to the scattered stratigraphic record and scarcity of independent age constraints in some areas, the precise age and underlying mechanism are still debated. We present integrated chronostratigraphic data from five sections in the eastern part of the system to reconstruct the flooding event distal from the strait to the Mediterranean. By applying modern Mediterranean biochronology (planktonic foraminifera and calcareous nannofossils), supplemented by an 40 Ar/ 39 Ar age on a tuff, we demonstrate that the widespread open marine settings in the NW Transylvanian Basin were definitely installed after 14.9 Ma (MMi4d biozone), and in most areas before 14.4 Ma. In the marginal study area in the SE Carpathian Foredeep, fully marine conditions likely set in slightly later (14.6-14.4 Ma). There, short-lived marine incursions into the brackish environment occurred since the latest Burdigalian ("pre-flooding phase"). The new ages overlap with the flooding in the majority of the Central Paratethys (~ 14.9-14.4 Ma), and with marine overflow into the Black Sea (14.85 Ma). We suggest that the transgression was driven by subsidence of the Pannonian Basin, by creating accommodation space and diminishing barriers between sub-basins, but was likely enhanced by a global sea-level rise. Finally, we speculate that the scarcity of all calcareous material in the SE Carpathian Foredeep before the mid-Langhian flooding might be related to pulses of nutrient-rich brackish and low pH water from the neighboring Black Sea Basin.

“…This period is characterized by the third transgression in the SGB, the second in the Badenian, correlated with the cycle TB 2.4. It is defined by the occurrence of H. waltrans, which is significant for the base of this transgression (Holcová et al 2018). At that time, the main extensional phase in the PBS was still in progress (Royden et al 1982).…”

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.
