Tracing Pre-Mesozoic Tectonic Sutures in the Crystalline Basement of the Protocarpathians: Evidence from the Exotic Blocks from Subsilesian Nappe, Outer Western Carpathians, Poland

Pre-Mesozoic exotic crystalline blocks within the Outer Carpathian flysch have potential to unravel nature of their eroded basement source(s) and reconstruct Paleozoic–Precambrian history Protocarpathians. Strongly tectonized Campanian–Maastrichtian grey marls in Subsilesian Nappe Western Carpathians Poland contain a variety different lithology types, including granitoids andesites. Petrological investigations coupled with zircon apatite U-Pb dating were performed on (subvolcanic) from locality Nappe. yields magmatic crystallization ages c. 293 Ma for microgranitoid 310 andesite block, inherited cores yielding Archean, Paleoproterozoic, Mesoproterozoic Cadomian ages. Whole rock trace element Nd isotope data imply that melt source was composed significant Neoproterozoic crustal component both microgranite andesite. The Late Carboniferous–Permian activity likely continues outside Belt can be linked Paleozoic transtensional zone, which is continuation Lubliniec–Kraków Zone extends under Moesia. This zone probably reactivated during Cretaceous transpressional regime Żegocina tectonic caused uplift Ridge intensive erosion.
