Devonian Clastic Wedges of the Acadian Orogeny
The Catskill Clastic Wedge
In the Mid-Atlantic region the Acadian orogeny took place in two separate impacts, one in eastern Pennsylvania, New Jersey and New York (the Catskill), and the second in southern Virginia (the Pocono). Each of these created a foreland Basin that filled with a clastic wedge (maps below).
Of the two clastic wedges, the Catskill was the largest, and has the most significant stratigraphic record. It was thickest in New York and Pennsylvania and thinned westward and southward.
