Short summary

We use numerical models to study the stresses arising from gravitational potential energy (GPE) variations and shear tractions associated with mantle convection in the Zagros–Iran region. The joint models predicted consistent deviatoric stresses that can explain most of the deformation indicators. Stresses associated with mantle convection are found to be higher than those from GPE, thus indicating the deformation in this region may primarily be caused by the mantle, except in eastern Iran.
