“…However, considering that the Dinarides were affected by regional Middle Miocene extension (e.g. Erak et al ., 2017; Matenco & Radivojević, 2012), followed by a Late Miocene transpressional phase, it is assumed that observed third phase faults correspond to the Late Miocene transpressional phase, likely occurring after 10–8 Ma (Schefer et al ., 2011; Mladenović et al ., 2014, 2019; Andrić et al ., 2015, 2017; Krstekanić et al ., 2022). Following the deformation development, the thermal springs emerging along relay‐ramp related faults led to the deposition of travertine on the slope and depressions (smooth and terraced slopes and pool facies associations) which is also observed in Pamukkale, Keykaya and Ballik, in Denizli Basin in Turkey (Özkul et al ., 2002; Kele et al ., 2011), and Mammoth Hot Spring in Yellowstone National Park, US (Chafetz & Folk, 1984; Pentecost, 1990).…”

The Carpathian slab retreat resulted in the opening of the Pannonian Basin (in the north and north‐east) and a clockwise rotation around the Moesian platform (in the east, Kräutner & Krstić, 2003; Krstekanić et al ., 2022). This rotation was accommodated by the Černa–Timok dextral strike–slip zone.…”

“…Previous studies suggested that the regional extension started in the middle Oligocene, ca 29 to 27 Ma (Erak et al ., 2017) and was controlled by a combined effect of Carpathian and Dinaridic retreating slabs (e.g. Matenco & Radivojević, 2012; Krstekanić et al ., 2020, 2022; Kostić et al ., 2021). Stratigraphic data show that the alluvial to lacustrine deposition in the Morava Corridor and marginal basins (for example, Levač Basin, Popovac Basin) started several million years later in the Early Miocene ( ca 17.0–16.2 Ma, Marković, 2016; Sant et al ., 2018a).…”

Travertines are terrestrial carbonates that are commonly associated with fault activity in extensional and transtensional basins. The faults serve as conduits for the rise and mixing of carbonate enriched fluids with thermal and meteoric CO2 inputs promoting travertine precipitation at the surface. Therefore, travertine successions provide key constrain on the faulting, depositional environments, fluid flow and climate. This work focuses on the travertine succession in the Miocene Levač Basin, the marginal basin of the Morava Corridor situated at the junction of the Dinarides and the southernmost Carpathians. Detailed sedimentological, geochronological (U‐Pb age, laser ablation – inductively coupled plasma – mass spectrometry) and structural analyses of the travertines are used to reconstruct the evolution of the feeding hydrothermal system. Furthermore, these data were used to understand the controlling factors governing alternation of fluid flows enriched in thermally generated and meteoric CO2, and precipitation of travertines in Levač Basin, and finally to elucidate the late stage of basin evolution. Four facies associations are distinguished within the succession, i.e. travertine slope, ridge, flat, and travertine flat under the fluvial influence. The results demonstrated that travertine deposition was controlled by north‐west/south‐west and north‐east/south‐east normal fault arrays. Stable isotope data show positive δ13C values (with δ18O being negative) shifting to negative in the distal and stratigraphically younger deposits implying dilution of deep hydrothermal fluids by mixing with meteoric waters. Finally, travertine deposits yielded a new U‐Pb age of ca 14 Ma indicating that the Middle Miocene extensional phase known from other intermountain basins in the Dinarides reached as far east as the Levač Basin and Morava Corridor.

“…The coexistence of thrust, strike-slip, and normal faulting has been documented in thick orogenic regions reaching crustal thicknesses above ∼60 km (e.g., Molnar and Tapponnier, 1978;Giambiagi et al, 2016) and in oblique convergent settings associated with strain partitioning (Chemenda et al, 2000;Krézsek et al, 2013). It is also observed in areas of indentation tectonics and lateral escape (Tapponnier et al, 1982(Tapponnier et al, , 2001Ratschbacher et al, 1991), synorogenic foreland rifting/transtension settings, where extension-transtension takes place in close spatiotemporal relation with plate-margin shortening (Sengör, 1976;Dèzes et al, 2004;Gianni et al, 2015), and in regions undergoing oroclinal bending (Allmendinger, 2005;Gutierrez-Alonso et al, 2012;Johnston and Acton, 2003;Krstekanić et al, 2021Krstekanić et al, , 2022 (Fig. 1).…”

“…These studies allowed a better understanding of deformation at a crustal or lithospheric scale and basinformation processes simulating scenarios that reproduce a particular tectonic regime or a succession of these, such as in basin inversion experiments (e.g., Buiter and Pfiffner, 2003;Bonini et al, 2012). Simulation of more complex scenarios, where several tectonic regimes act in concert to produce intricate patterns of deformation, allowed us, for instance, to gain insights into thrust-wrench interferences (e.g., Duarte et al, 2011;Rosas et al, 2012Rosas et al, , 2015Fedorik et al, 2019), back-arc-convex orocline formation (e.g., Krstekanić et al, 2021Krstekanić et al, , 2022, regional deformation in the eastern Asian lithosphere triggered by the collisional far-field effects of India and/or Pacific subduction (e.g., Tapponnier et al, 1982;Davy and Cobbold, 1988;Fournier et al, 2004;Schellart et al, 2019), or the formation of the V -shaped south China oceanic basin (Le Pourhiet et al, 2018;Jourdon et al, 2020). In addition, brittle-ductile analog and 3D numerical experiments have been applied to understand complex regional deformation resulting from the close interrelation between the indentation of Arabia, the lateral escape of Anatolia, and back-arc extension in the Aegean region (e.g., Martinod et al, 2000;Sternai et al, 2014;Philippon et al, 2014) and lateral escape and extension in the eastern Alps resulting from the indentation of the Adriatic plate (Ratschbacher et al, 1991;van Gelder et al, 2017).…”

Abstract. Geological settings characterized by multiple coeval tectonic regimes provide a unique opportunity to understand complex interactions among different geodynamic processes. However, they remain comparatively less studied from an experimental point of view than areas with more simple patterns of deformation resulting from primary plate–boundary interactions. Here, we carried out analog experiments involving simultaneous shortening and orthogonal extension under different rheological conditions, including the effect of crustal inheritance. We performed brittle experiments and brittle–ductile experiments to simulate cases of “strong” and “weak” crusts, respectively. We present two types of experiments: (i) one-stage experiments with either shortening only or synchronous orthogonal shortening and stretching and (ii) two-stage experiments with a first stage of stretching and a second stage with either shortening only or synchronous orthogonal shortening and stretching. In our models, deformation is accommodated by a combination of normal, thrust, and strike-slip faults with structure location depending on boundary conditions and crustal inheritance. For brittle models, we show that the three types of structures can develop at the same time for intermediate ratios of stretching (extension) over shortening rates (1.4<Ve/Vs<2). For lower ratios, deformation is accommodated by in-sequence shortening-orthogonal thrust faults and stretching-orthogonal normal faults at the edges of the model (when Ve>0). For larger ratios and for the same amount of stretching, deformation is accommodated by normal faults at edges and in the center of the model as well as by conjugate strike-slip faults at the edges of the model. For brittle–ductile models, we always observe strike-slip faults that crosscut the entire model. They are associated with shortening-orthogonal thrust faults for models with low Ve/Vs and no initial extensional stage or stretching-orthogonal normal faults for models with high Ve/Vs and an initial extensional stage. Whatever the crustal strength, the past deformation history, and the stretching / shortening ratio, both normal and thrust faults remain with similar orientations, i.e., stretching-orthogonal and shortening-orthogonal, respectively. Instead, strike-slip faults exhibit orientations with respect to the shortening direction that vary between ∼0 and ∼65∘. Strike-slip faults parallel to the shortening direction develop in previously extended portions of models with a brittle–ductile crust, while strike-slip faults with a high angle form at the boundaries of the brittle model, their orientation being to some extent influenced by pre-existing or newly forming graben in the center of the model. We also show that extensional structures formed during a first stage of deformation are never inverted under orthogonal shortening but can be reactivated as normal or strike-slip faults depending on Ve/Vs. Our experiments reproduce V-shaped conjugate strike-slip systems and normal faulting during compression similar to structures observed in the Tibetan Plateau, the eastern Alps, western Anatolia, and the Central Asia orogen. Models with two-stage deformation show variable extensional to strike-slip reactivation of former extensional basins during basin-parallel shortening, which resembles synorogenic foreland transtensional reactivations documented in the Baikal and Golfo de San Jorge basins.
