This study reconstructs the Miocene tectonic evolution of the Western Tauern Window (TW) in the Eastern Alps, where indentation, extrusion, and exhumation interacted to expose deep crustal nappes. Using an integrated 2-D, 3-D, and 4-D modeling approach that combines geological, thermochronological, and geophysical data, the study retrodeforms the Western Tauern Window in 4-D. The results show that the initial upright folding of a flat-lying duplex structure (between ca. 23 - ca. 17 Ma) gave way to thrusting along the Sub-Tauern ramp (ca. 17 - 10 Ma). Different indentation directions (NW–NE) of the Dolomite Indenter eventually led to asymmetric detachment of the lower crust of the Dolomite Indenter, influencing the deformation style of the upper crust. The new quantitative models clarify long-debated aspects of the tectonic evolution of the TW.
