Short summary
We studied Middle Triassic calc-alkaline rocks from the Alps–Dinarides transition zone to clarify their origin and tectonic provenance. Zircon geochronology dates them at 246 to 240 million years. Phengitic muscovite geobarometry reveals high-pressure, low-temperature (HP–LT) metamorphic overprint, indicating deep burial during Cretaceous Eoalpine subduction. Their present tectonic position reflects large-scale post-metamorphic extrusion, revising present understanding of the tectonics of the Alps–Dinarides transition zone.
