WebApr 13, 2024 · Flysch (Melloussa, Tisirene, Numidian) It mainly consists of a stack of nappes of turbiditic sediments, deposited within the Liguro-Maghrebian basin and moved after the closure of Maghrebian Tethys (between the former microcontinent and Africa) and the detachment from the basement. Flysch is a sequence of sedimentary rock layers that progress from deep-water and turbidity flow deposits to shallow-water shales and sandstones. It is deposited when a deep basin forms rapidly on the continental side of a mountain building episode. Examples are found near the North American Cordillera, the Alps, the Pyrenees and the Carpathians.
