Clastic wedge

They begin at the mountain front, thicken considerably landwards of it to a peak depth, and progressively thin with increasing distance inland.

[1] Some examples of clastic wedges in the United States are the Catskill Delta in Appalachia and the sequence of Jurassic and Cretaceous sediments deposited in the Cordilleran foreland basin in the Rocky Mountains.

They are also a characteristic of passive continental margins such as the Gulf Coast; these are quiescent environments, where sediments have accumulated to great thickness over a long period of time.

Inversely, as for that of the autogenic sedimentary process, it relates internal or intrinsic mechanisms that directly effect geological structures and systems.

[4] As of how such methods relate to that of sedimentary cycles and clastic wedges, they come into effect by shaping and weathering surfaces (allogenic) that will conclude in becoming compacted and cemented (autogenic) to the area of crust.
