Mesas and buttes are formed by differential erosion where a tough layer of rock protects weaker ones below it. If the top layer of rock is a volcanic rock such as basalt, then it was formed as an indirect result of volcanic activity. The whole rock formation may not by volcanic, as lava may flow over sediment.
