Geophysicists have made discoveries related to the movement of the earth's mantle and crust in various regions, including the Caucasus and the Iranian plateau. Research suggests that the process of subduction, where one tectonic plate is pushed beneath another, has a complex aftermath that can involve the relamination of crust, slab tearing, and changes to the mantle. The specifics of these processes and their effects on the surrounding geology are being studied in areas such as the Betic Cordillera and the Central Anatolian Plateau.
