The final major orogeny, the Alleghanian Orogeny, occurred around 325 to 260 million years ago during the [[Carboniferous]] and [[Permian]] periods. This orogeny was the result of the collision between [[Gondwana]] and Laurentia, leading to the formation of the supercontinent [[Pangaea]]. The immense tectonic forces generated during this collision caused significant folding, faulting, and metamorphism of the Appalachian rocks. | The final major orogeny, the Alleghanian Orogeny, occurred around 325 to 260 million years ago during the [[Carboniferous]] and [[Permian]] periods.
