Tectonic stresses governed by the Arabia – Central Iran collision are transferred throughout Iranian Plateau. The orientation of maximum horizontal stress (σ 1 ) significantly changes (~90°) in Persian block NW Iran. However, exact spatial extent and boundary conditions for these poorly defined. This study investigates late Cenozoic regime a key region including Mahneshan Mianeh Basin (MMCB), G...
