Flysch (/ flɪʃ /) 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.

Jul 1, 2017 · 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.

flysch, sequence of shales rhythmically interbedded with thin, hard, graywacke-like sandstones. The total thickness of such sequences is commonly many thousands of metres, but the individual beds are thin, only a few centimetres to a few metres thick.

Flysch is a typical geosynclinal formation that marks the pre-orogenic phase of the development of eugeosynclines, miogeo-synclines, or both. In the preorogenic phase, a cordillera emerged along a flysch trough.

The waste products that accumulate as a deposit flanking mountains and built in part of the deformed flysch make up the molasse. In field practice the groups of sediments called flysch and molasse, or facies of them, are formations in the American sense.

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.

Flysch refers to a type of sedimentary rock formation consisting of mixed terrigenous siliciclastic and calcareous sediments deposited as deepwater turbidites in a proto-trench along continental margins, indicating the initiation of convergence and subduction in geological processes.

Flysch and Molasse are terms that describe different sets of sedimentary facies associated with orogenic belts. Molasse is defined as terrestrial and shallow marine deposits formed nearest the rising mountain front.

Scientifically-speaking, the Zumaia flysch is our ensign. Its international importance has been recognised by UNESCO and the International Union of Geological Sciences (IUGS), but there is much more to the park than the flysch.

Dec 1, 1997 · It is demonstrated that during the development of the North Alpine foreland basin neither inherited paleobathymetry nor changing lithospheric strength of the underthrust European passive margin played a significant role in the flysch to molasse transition.
