Late Campanian (74–71 Ma) Arabia–Eastern Anatolia Collision and Its Geodynamic Implications

Tectonics, Volume 45, Issue 7, July 2026.
Abstract The East Anatolian Plateau is a major collisional feature within the Tethyan realm formed as a late‐stage result of the collision between East Anatolia and the Arabian Platform. The timing of this collision is highly debated, with estimates from the Late Cretaceous to the Miocene.
