investigation of mantle kinematics beneath nw iran with the comparison of teleseismic direct s waves and sks

The present tectonics of iran results from the continental convergence of the arabian and eurasian plates. our study area, nw iran and west alborz, is located in the central part of arabia-eurasia collision zone, consists of an assemblage of distinct lithospheric blocks such as part of the central iranian plateau, the south caspian basin, talesh mountains, alborz mountains.in order to understand the kinematics and dynamic of continental deformation, the state of deformation and understand howupper mantle deform in between of each tectonic parts and in the transform boundaries between them along continental collision, it is important to have a very good estimate of the mantle flow and the mantle deformation. earth’s mantle deformation, can be inferred from observation of seismic anisotropy, revealed by the polarization of shear waves travellingthrough an anisotropic medium.
