the Tisza-Dacia mega-tectonic unit, but also the allochthonous flysch nappes of the Pienides, i.e. the eastern tip of the ALCAPA mega-tectonic unit. Well-documented opposed rotation of the re-mainder of ALCAPA necessitates a detachment of this eastern tip of ALCAPA after 18.5 Ma. The most likely location for this detach-ment zone is along the margins of the Transcarpathian depression. During a second (post-12 Ma) stage, counterclockwise rotations of up to 30 ° affected the entire working area. Regarding timing and magnitude, these second stage rotations are similar to rotations documented for the East Slovak basin, but different from those re-ported from the South Apuseni Mountains and the Central and In-ner West Carpathians located west of the East Slovak basin. Western Outer Carpathians consist of several north-verging Nap-pes. The Silesian Nappe, the subject of the present study, is situ-ated between tectonic units from which there are a number of Ter
