“…Tectonics 10.1002/2016TC004133 [Schneider et al, 2015] is aligned with the minima of the curves of fission track ages, suggesting that cooling of all three thermochronological systems resulted from one and the same process. The age difference between apatite and zircon fission tracks in the hinge of the dome is smaller than in the limbs (Figure 10b), suggesting faster cooling in the core, as expected for exhumation during folding and erosion.…”

“…The youngest ages along the dome‐perpendicular cross section (Figure b) are located within the core of the western subdome (Figures , , and b), close to the northern limb of the dome (Figure b), probably reflecting an asymmetric construction by antiformal stacking of the nappes during northward thrusting [ Lammerer et al ., ]. The minimum of the bell‐shaped curve of the U‐Pb on apatite data (Figure b) [ Schneider et al ., ] is aligned with the minima of the curves of fission track ages, suggesting that cooling of all three thermochronological systems resulted from one and the same process. The age difference between apatite and zircon fission tracks in the hinge of the dome is smaller than in the limbs (Figure b), suggesting faster cooling in the core, as expected for exhumation during folding and erosion.…”

“…The Cenozoic metamorphic history of the Tauern Window started with Eo-Oligocene subduction of the oceanic-derived units and the distal European margin [Schmid et al, 2013] below the (Austroalpine) Adriatic Plate. This phase was followed by a Barrow-type metamorphism [e.g., Bousquet et al, 2008], whose peak is inferred to have been attained between 30 and 28 Ma [Reddy et al, 1993;Selverstone et al, 1992;Christensen et al, 1994;Inger and Cliff, 1994;Thöni, 1999] or 34 and 30 Ma [Schneider et al, 2015]. Cooling and exhumation followed the peak of metamorphism from early Oligocene to late Miocene [e.g., Hoinkes et al, 1999;Handy and Oberhänsli, 2004].…”

“…These ages document the older exhumation history of the dome. Rb/Sr and K/Ar biotite [Most, 2003] and U-Pb apatite ages [Schneider et al, 2015] also show a bell-shaped curve on the age versus distance diagram of Figure 10b. However, these bell shapes are less constrained than for the other method because of the small amount of data.…”

Orogen‐parallel extension and orogen‐perpendicular shortening accommodated by folding acted at the same time to exhume the Tauern Window. In order to investigate the relative contribution of upright folding and erosion and of extensional denudation for exhumation, we provide compilations in map view of previous and new zircon and apatite fission track ages. These age maps show that isoage contour lines are subparallel to the axial planes of large‐scale, upright folds. On age versus distance diagrams, along a profile perpendicular to the dome axis, all thermochronometers show bell‐shaped curves with younger ages in the hinge area of the dome and age differences between different chronometers decreasing from the limbs to the hinge area. All these observations suggest that folding synchronous with erosion was largely responsible for exhumation of the Tauern Window. The younger ages and the higher fold amplitudes of the western subdome compared to the eastern one are corroborated by the results of inversion of cooling ages that show higher exhumation rates in the west. These reflect one and the same shortening and folding event that affected the entire Tauern Dome synchronously, but at higher rates than that in the western subdome. Only during Pliocene time were exhumation rates slightly higher along the normal faults bordering the window; hence, extensional unroofing may have dominated exhumation in the Pliocene. The northward displacement of the Dolomites Indenter was associated to a clockwise rotation, which caused increased amounts of shortening westward, hence higher uplift and exhumation rates in the western subdome.

Apatite (U-Th-Sm)/He ages from the Karawanken Mountains range between 12 and 5 Ma and indicate an episode of fault-related exhumation leading to the formation of a positive flower structure and an associated peripheral foreland basin. In the Southern Alps, apatite (U-Th-Sm)/He and fission-track data combined with previous data also indicate a pulse of mainly Late Miocene exhumation, which was maximized along thrust systems, with highly differential amounts of displacement along individual structures. Our data contribute to mounting evidence for widespread Late Miocene tectonic activity, which followed a phase of major exhumation during strain localization in the Tauern Window. We attribute this exhumational phase and more distributed deformation during Adriatic indentation to a major change in boundary conditions operating on the orogen, likely due to a shift from a decoupled to a coupled system, possibly enhanced by a shift in convergence direction.
