Carpathian Flysch Belt
The Carpathian Flysch Belt is an arcuate tectonic zone included in the megastructural elevation of the Carpathians on the external periphery of the mountain chain. Geomorphologically it is a portion of the Outer Carpathians. Geologically it is a thin-skinned thrust belt or accretionary wedge, formed by rootless nappes consisting of flysch – alternating marine deposits of claystones, shales and sandstones which were detached from their substratum and moved tens of kilometers North. The Flysch Belt and the Neogene volcanic complexes are the only extant tectonic zones along the Carpathian arc.
