Compare the Taconic, Caledonian, and Acadian orogenies in terms of the tectonic forces that caused them and the
sedimentary features that resulted. What will be an ideal response?
All three orogenies relate to the closing of the Iapetus Ocean. The Late Ordovician Taconic
Orogeny in New England resulted from convergence with Laurentia; highlands shed the
Queenston clastic wedge westward onto the craton. Closing of the Iapetus in the Late
Silurian-Devonian caused the Caledonian orogeny and its North American counterpart, the
Acadian orogeny (which also involved the encroachment of Gondwana on Laurasia).
Resulting orogenic highlands shed the Catskill Delta (clastic wedge) to the west, and the Old
Red Sandstone clastic wedge to the east.
