(Geological Science) (sometimes not capital) a marine sedimentary facies consisting of a sequence of sandstones, conglomerates, marls, shales, and clays that were formed by erosion during a period of mountain building and subsequently deformed as the mountain building continued. The phenomenon was first observed in the Alps

The study area is covered by the rocks ranging in age from Triassic to recent/subrecent, and can be divided structurally, into three domains, Tungi-Ahmadun Syncline Area, Khanozai-Torkhula Ophiolite Segment and Murgha Zikriazai Flysch Segment.
A good example are the Flysch Carpathians, where so far almost 58,000 landslides have been inventoried in the Polish part of the area, and their approximate number here may exceed even 100,000 (Wojcik and Wojciechowski, 2016).

These carbonate platforms tectonically overlay a pile of Mesozoic-Tertiary pelagic basin successions belonging to the Lagonegro unit, Neogene flysch deposits, and shallow-water and slope facies carbonates of the Apulian Platform ([40-43] and references therein).
The most widespread lithotypes are limestones and dolomites (34%), alluvial sediments and clays (22%), volcanic rocks (18%), and flysch deposits and arenaceous assemblages (17%) (Geoportale Nazionale, 2016).
