3d velocity model of crust beneath the zagros collision zone from ambient noise tomography

Zagros collision zone was formed by collision between the arabian plate and central iranian micro-continent. the zagros belt is important in terms of one of the youngest and most active continental collisions while interactions with its deformation zone continues. in order to study the crustal structure across the northern part of the zagros collision zone, we process continuous vertical-component seismograms recorded by ~85 broad-band stations situated in the east of iraq,zagros mountains, central iran and western alborz (figure 1-a). to estimate the inter-station green functions by crosscorrelation, we employed a method described by bensen et al. (2007).
