Look at the geography of the western United States because that is exactly what happened. The Farallon plate was subducted under the north American plate a couple million years ago. The rift zone from the Farallon plate is actually stretching the continental crust of the North american plate creating features such as the Baisin and Range, Colorado Plateau, or even possibly the Yellowstone volcanic chain.
