Flysch is a sequence of sedimentary rocks that is deposited in a deep marine facies in the foreland basin of a developing orogen. Flysch is typically deposited during an early stage of the orogenesis. When the orogen evolves the foreland basin becomes shallower and molasse is deposited on top of the flysch. It is therefore called a syn-orogenic sediment (deposited contemporaneously with mountain building).

 

Les flyschs sont des formations rocheuses syn-orogéniques (qui se forment en même temps que les montagnes) formées par des alternances de bancs de grès à la base de la formation et de schistes vers le haut de la formation.

Ils se forment par dissolution des fragments rocheux arrachés aux montagnes dans les mers périphériques : ce sont des turbidites.
