The Caledonian one produced much of the topography of Great Britain while the Appalachians have not experienced this process since the end of the Permian though the western US has been heavily impacted by the subduction of the Farallon plate causing the Nevadan, Sevier and Laramide ones.
They come in hercynotype, alcinotype, and cordellian varieties depending on the cause.
