If the extension activity is extensive and deep enough, a backarc basin can develop into a continental rifting zone. When a layer of magma moves over a crystalline structure in the crust, a volcanic eruption occurs. Igneous rocks containing magnetic minerals like magnetite typically provide the most useful data. Identify convergent boundaries, including subduction and collisions, as places where plates come together. The eruption threw 1, 000 cubic kilometers of ash and magma into the atmosphere, some of which was found as far away as Mississippi. In rare cases, such as a few locations in Iceland, rift zones display the type of volcanism, spreading, and ridge formation found on the ocean floor.

The Persian Gulf is possibly the best modern example, created entirely by the weight of the nearby Zagros Mountains. When a subducting slab becomes stuck and cannot descend, a massive amount of energy builds up between the stuck plates. Eventually, plate sections located between large faults drop into deep depressions known as rift valleys, which often contain keystone-shaped blocks of down-dropped crust known as grabens.
