Mount Ararat lies within a complex, sinistral pull-apart basin that originally was a single, continuous depression. The growth of Mount Ararat partitioned this depression into two smaller basins, the Iğdir and Doğubeyazıt basins. This pull-apart basin is the result of strike-slip movement along two en-echelon fault segments, the Doğubeyazıt–Gürbulak and Iğdir Faults, of a sinistral strike–slip fault system. Tension between these faults not only formed the original pull-apart basin, but created a system of faults, exhibiting a horsetail splay pattern, that control the position of the principal volcanic eruption centers of Mount Ararat and associated linear belt of parasitic volcanic cones. The strike-slip fault system within which Mount Ararat is located is the result of north–south convergence and tectonic compression between the Arabian Platform and Laurasia that continued after the Tethys Ocean closed during the Eocene epoch along the Bitlis–Zagros suture.
