This paper presents the deep structure features resolved across four profiles of Zagros 2001, Kopeh Dagh, Zagros 2003 and Iran-China. The absolute S-wave velocity map (obtained from joint inversion of receiver function and dispersion curve) and geometry of intra-lithospheric boundaries (obtained from migration of receiver functions) are presented for the three first profiles and the relative velocity variation of P-wave velocity is displayed for the fourth one. The models show that convergence in northern portion of the Zagros (Lorestan arc) is accommodated by underplating of Arabian plate beneath Central Iran while it is partly accommodated by internal deformation of Arabian plate in southern part of the Zagros (Fars arc). Teleseismic tomography across Iran-China profile confirms existence of a high velocity feature, probably a broken slab, beneath the Central Iran.
