Description:
In the Reggiano mountains the surfacing of flyches, rocks formed by a regular alternation of calcareous layers and marly layers are very widespread; A classical example are the "Muri del Diavolo" (Devil walls) of the slopes of mt Duro of Casina, where the softer (marly) layers, have been profoundly eroded, while the calcareous ones, which are harder, have been conserved and appear quite evident. The flysch were formed by currents of alluvial matter which would fill a marine basin which was rapidly decreasing (geosynclinal); the sediment thus deposited subsequently surfaced because of the orogenetic thrusts of the earth's crust, undergoing at the same time bending and sliding on moveable sediments (clay), in such a way as to run, at time, great distances compared to the place of origin.
A spectacular example of flysches is in Val d'Asta, in the town of Villa Minozzo.
